This project was established to develop a facet of the work involved in a preceding UNDP/ILO-assisted project* designed to establish national trade standards, trade testing and certification processes and to develop instructor training. In early 1972, the National Industrial Training and Trade Certification Board (NITTCB), under the Ministry of Labour and Manpower, had begun operations directed toward the co-ordination and rationalisation of industrial trade training as a key factor in the development of manpower resources. The Board's technical needs were then furnished by the Training Service of the Ministry and two standing technical committees, the Central Trade Standards and Testing Committee (CTSCT) and the Central Apprenticeship Committee (CAS), which operated through tripartite ad hoc committees in preparing the national standards. 2. In May 1973, the then Prime Minister directed all agencies concerned vith industrial vocational training to adapt their training programmes to meet the standards established by the NITTCB. The NITTCB's own role was to change from a deliberative to an action-oriented one and it was to become a separate entity within the Ministry with its own technical and administrative resources. 3. The NITTCB Technical Unit was established in April 1974 to service the Board in achieving its objectives and implementing its functions. Its organisation chart and the functions of its main sections appear as Annex I, which includes the list of job descriptions approved by the Government for the Technical Unit posts. 4. Initially, the only technical staff consisted of three senior instructors seconded from the Industrial Training Institute at Kuala Lumpur and it was recognised that both this nucleus and the additional staff to be recruited would need assistance and guidance during the formative period. Further UNDP assistance was therefore sought. > 5. The purpose of this project is to assist in establishing and developing the Technical Unit of the NITTCB, in order to give the Board an effective full-time technical secretariat. With a multiplicity of training agencies functioning throughout the country, standards and systems vary widely. The Technical Unit will assist all training agencies in adapting their programmes to meet the national standards. 6. The project was to further assist the NITTCB in stimulating and providing industrial training to meet the needs of the economy and of individuals, making maximum use of training resources. The mobility of labour and maximum opportunity for on-going industrial training for individuals was to be promoted by establishing and maintaining realistic industrial trade standards. 7. Within this framework, the immediate objectives called for continuous in-service training for the staff of the Technical Unit, and assistance to it in establishing liaison between sources of labour market information and training. A method for assessing: the needs of industry and manpower and the facilities available and required for training was called for. 8. The existing pilot scheme of trade testing and certification was to be expanded and additional trade standards developed. Seminars and workshops for industrial trainers, examiners and technical administration personnel were to be conducted. A mechanism for formulating and reviewing training standards, syllabi and course materials would be established. Criteria for evaluating training programmes would be set up, along with a system for "feedback" of training and test results data to training agencies. Schemes would be implemented to ensure the collection and dissemination of industrial training information. A modular approach to trade instructor, industrial training officer and industrial supervisor training was to be developed. In-plant training activities of the various training agencies would be correlated, making maximum use of existing resources and available trained personnel, fortified by the structuring of the training of additional in-plant trainers. Finally, an evaluation would be made of the national apprentice training programme with respect to its relevance to Malaysia today, to be followed by such recommendations for its modification as appeared desirable. 1 MAL/69/521 - "Industrial 1969 to 31 March 1974.

During the life of the project, significant quantitative achievements have been made in developing trade standards, testing and certification. 12.

The Board is now involved in testing and certification from all training agencies, industry and apprenticeship. for candidates 17. All training agencies now support the industry-defined standards and have geared their training to meet the standards, with the exception of the vocational schools. 18. The following recommendations are made: (a) The training agencies which demonstrate the ability to consistently achieve good test results should be, on meeting certain conditions, accredited to conduct their own tests. (b) A gauge room for checking certain test pieces should be set up on the premises of the Technical Unit. (c) For many workers with broad bases of skills who need apply only a limited number of in-depth skills in their jobs, trade standards and tests at the basic level could be used, but with certification geared to progressive testing in line with training modules of employable skills. (d) For those candidates for testing who, having learned their trades on the job, have no knowledge of theory and/or whose jobs may not require certain skills, training should be offered along modular lines. Existing facilities can be used during school recesses, evenings and weekends. (e) In order to best serve workers and industry, and in view of the Technical Unit's limited resources, it is necessary to restrict the production of standards to those for which there is a firm need. Similarly, the Technical Unit should confine itself to the on-going activities of standard setting, testing, certification and curriculum development. (f) The problem of recruitment of technical staff for the Technical Unit may be solved by finding staff from the training agencies for seconding to the Unit on two-year cycles. They should be persons whose qualifications meet the job descriptions. (g) Increased publicity for testing must be accompanied by growth in the organisation and staff of the Technical Unit, otherwise the demand for training will overwhelm the present resources of the Unit. (h) Heretofore, certificates have been awarded in an annual ceremony. In order that successful candidates may more guickly reap the material benefits of certification, successful candidates should be notified within a week of completing the test. The formal ceremonies might be discontinued. To eliminate confusion with regard to certification of apprentices, the training agency might issue its own certificates, but any apprentices who wish to do so may go on to take the NITTCB test as well. (i) (j) The role of the vocational schools should be defined and, if possible, they should be accredited for NITTCB theory tests, with arrangements being made to intensify the education and to round out the apprentices' skill training. - 4 II. TECHNICAL BACKGROUND 19. The NITTCB was established in December 1971 and establishing national trade standards and developing certification process based upon such standards. made responsible a skill testing for and 20. When the current project began, trade standards had been prepared for 17 trades and a pilot testing programme had been carried out involving a total of 384 candidates in 7 trades at 7 different centres, standard setting, testing and certification activities are listed in Annex IIA. Annex IIB lists the related national trade standards and syllabi. 21. The above activities had been undertaken by a small unit of three technical co-ordinators recruited from the instructional staff of the Industrial Training Institute of the Ministry of Labour and Manpower, with ILO assistance under Project MAL 69/521, and were located with and directly responsible to the Training Service of the Ministry of Labour and Manpower. 22. The present project came into being following a decision of the Prime Minister to have the NITTCB become an action-oriented body with its own technical unit. The Technical Unit of the Board, consisting of the three original technical co-ordinators seconded to it, became operational on 1 April 1974 - the commencement date of the project. The up-to-date roster of NITTCB Technical Unit staff and ILO expert staff is listed in Annex III. E-1528-2:33 - 5- III. WOR£_A£CQli£I1£§aED standard setting Standards.committee,composition 23. In reviewing standards already set and in formulating new ones, it was accepted that it was the responsibility of industry to objectively define its current skill requirements, and in a Malaysian context. The main objective of the training agencies would be that of training students to meet these requirements. 21. In reviewing and formulating new trade standards, it was found that ideal standards committee should: (i) (ii) (iii) (iv) the consist of approximately 12 members, all drawn from industry; include members representative of the public sector, private sector the trade unions; and include, as well, direct nominations of suitable people known to the Technical Unit in addition to nominees of employers' organisations and trade unions; represent both large and small organisations, management and workers. shop-floor 25. Where standard-setting committees were formulated in line with the stated ideal composition, the cross-section of representation and the ensuing exchange of ideas were reflected in the high quality of standards produced. 26. When committees were formed which deviated from the ideal, were unsuccessful, as seen below: the results (i) In one committee where members were not exclusively drawn from industry and representatives from training agencies were involved, the standards produced reflected what the agencies were teaching rather than what industry required. Those standards had subsequently to be redrafted. (ii) In three cases where pressure was applied in order to achieve quantity, as opposed to quality, the number of committee menbers was restricted and consequently discussions limited, with the result that omissions and errors subsequently became apparent. Selection of standards 27. The bases for selecting trades for which national set have not been constant. standards have been (i) Where the basis for selection was an apprenticeable trade for which training was offered by the Ministry of Labour and Manpower, candidates subsequently appeared for the related tests. (ii) Trades selected for which training was offered by training agencies other than the Ministry of Labour and Manpower resulted in a demand for related tests and the introduction of some standards pertaining primarily to female occupations, i.e. tailoring and dressmaking. (iii) Pressure was applied to introduce standards where no evidence of need was substantiated. A case in point is the standard for commercial driver; no applications have been received for the related tests. (iv) Suspect manpower projections and inspired guesses where the underlying motive was to produce quantities of standards led to the selection of trades for which tests have not yet been requested. While it may be too early to pronounce on the value of these standards, it remains doubtful. E-1528-2:33 - 6 - Functioning of committees 28. It was originally planned that each standard-setting committee would be chaired by a member of the CTSTC* so that, when the committee reported back to the CTSTC, its chairman would be present to clarify any doubts and explain any seeming ambiguities. In fact, the practice was unsuccessful because the CTSTC-nominated chairman often did not feel able or obliged to assume the duty, and this resulted in delays and cancellations of standard-setting committee meetings. 29. A subsequent approach was to appoint the chairman of the CTSTC, namely the Director-General of the Ministry of Labour and Manpower, as the chairman of all standard-setting committees. This was not completely satisfactory since the cultural background tends to inhibit joint consultation with those in authority, and to restrain the informality which encourages involvement in the necessary debate and discussion. 30. The third approach proved the most successful, promoting total involvement in an informal atmosphere, and is the one currently in use. It involved the training and then the naming of a member of the Technical Unit as chairman at the initial meetings; then, as the abilities of the various members became apparent in the course of subsequent meetings, the chairmanship was handed over to the most suitable one. 31. Three differing methods have been utilised committees on their task with differing results: to launch standard-setting (i) Initially, the committees were given a general briefing on their tasks by a member of the Technical Unit and then allowed to formulate their own approaches. This proved unsuccessful and time consuming, as members were hesitant to initiate proposals. (ii) Following the failure of (i), it was believed that members would be more comfortable if they were provided with a working draft prepared by a trade "expert" and which they were requested to modify. The drawback to this method, however, was that the expert felt the need to protect and justify his proposals; discussions were stifled, and members were reluctant to criticise and suggest changes. (iii) The successful system, which has now become standard practice, involved the anonymous preparation of a draft which deliberately included controversial items and incorrect statements; further, no foreign expert thus defends the proposals. This approach has resulted in lively debate and argument, with members most eager to contribute. 32. The time, frequency and duration of standard-setting committee were subjected to experimentation which led to the following conclusions: (i) (ii) (iii) meetings Meetings are best scheduled for early morning and not on Mondays and Fridays which appear to be key days in industry. The early morning start overcomes the difficulty members face in leaving their places of work once they arrive and become involved. It is preferable to hold meetings weekly in order and interest. to maintain tension Meetings restricted to a maximum of three hours produce the best results; those of longer duration tend to become counter-productive. 3 3. Throughout the trade standard-setting programme, it has been possible to obtain the wholehearted co-operation of industry even though no payments are made to committee members, when personal contacts have been established by Technical Unit members and reliance not placed on formal letter writing. 34. The Technical Unit was responsible for providing revised drafts for each meeting and decisions were arrived at not by vote, but by talking out problems and through compromise. The time committees required for finalising their proposals for 1 The Central Trade Standards and Testing Committee (CTSTC) was a standing committee of the Board to which all ad hoc standard-setting committees were responsible; the committees reported to the CTSTC or were replaced by a standard technical committee. £-1528-2:33 - 7the standards varied with differing trades and ranged from 10 to 30 meetings of 2 to 3 hours' duration each. 35. The format, designed by-the expert, for all trade standards has been standardised and appears in Annex IV. Although the format is not mandatory, each trade to date has been divided into the three grades shown. 36. The important feature of the trade standards is the stress on practical performance and this is emphasised in the preface to the practical reguirements. In all cases, the criterion for passing the practical exercises is perfection and indicated by "must_be_able_to". The "must" is omitted in connection with theory and only the words "to know" are used. 37. Two standards have been revised during the project; provision exists for all standards to be reviewed at the end of two years of use or when errors are discovered or technological developments demand change. l£§de_test_settin^an^_ design 38. In extending trade testing from a limited pilot scheme in national scheme during the project lifetime, it was established that: (i) (ii) (iii) all tests should cover as comprehensively as possible all in the relevant trade standards; 1973 items to a listed tests should always be presented in such a way as to ensure the complete understanding of the candidate under testing; practical tests should, where possible, for the sake of interest, result in the production of a useful product. economy and 39. Objective number (i) has been achieved to a large degree and without any major problems. Problems initially arose with practical tests in objective (ii) because, in a country where orthographic projection drawings are little used in industry, test candidates had difficulty in visualising three dimensionally. This difficulty is compounded by the fact that even simple tests,.such as shuttering for concrete formwork, may necessitate relatively complex drawings to illustrate what is required. The solution arrived at for basic-level tests has been the provision of pictorial views in addition to orthographic projection drawings, and the provision wherever possible of complete models of the task required. In the case of theory tests both at basic level, which is an oral test, and in the written examinations for intermediate level, it is standard practice to use two languages - both English and Bahasa Malay: students have the option of using either one. HO. In striving to attain objective (iii), useful products have been produced during tests for such trades as cabinet making and joinery, but this is not practicable in trades such as bricklaying and plumbing. In machining and turning tests, it was arranged for testing to centre upon a common replacement part used in the cigarette manufacturing industry. A manufacturer was found who was prepared to supply material free in return for the end product. This idea has not succeeded to date because of the poor quality of test pieces obtained, but should becoae viable with improvements in training and better materials. The setting of, trade tests 41. Trade test panels have been formed for each trade for which standards have been set. The panels include, but are not confined to, members of the standard-setting committees and §.11 members are from industry. By including persons responsible for the standard setting in the trade test panels, the philosophy governing the standards becomes implicit in the implementation stage. Members of the trade test panels are responsible, with guidance from the Technical Unit, for submitting draft test questions which are subsequently scrutinised and debated by the panels. When the panels are satisfied with the scope and quality of the questions, the Technical Onit presents them professionally. During the project lifetime, 26 practical tests and 28 theory tests have been formulated in this manner. Before any test is given to candidates, it is performed by the member of the test panel responsible for that test so that realistic time norms are established and problems anticipated. E-1528-2:33 - 8 - 42. Pilot tests conducted prior to the project resulted in following norms in marking tests: (i) (ii) determining Candidates taking similar tests in differing geographical differing examiners, should be assessed on the same bases. areas, the with Any certificate issued following testing must signify that the holder has unqualifiedly demonstrated his ability to perform the tasks specified in the relevant trade standard. 43. The earlier pilot tests had been conducted on an ad hoc basis and disparities in assessment by differing examiners noted. Every effort has been made during this project to eliminate this problem and the procedures described below have been developed and adopted. (i) Each test panel nominates a chief examiner drawn from industry. (ii) Chief examiners are present when test panels responsible for formulating the test questions discuss the marking scheme. Each examiner then receives training in examination duties from the staff of the Technical Unit. (iii) Irrespective of geographical location, the appointed chief examiners were present at the initial tests conducted in every trade in 1974. These examiners were supported by, and in charge of, examiners who had been, wherever possible, recruited locally and who had been thoroughly briefed by the staff of the Technical Unit. This "on-the-job" training of examiners by the chief examiner and the Technical Dnit resulted in the validation of more than 200 examiners spread over 22 trades in differing geographical areas. (iv) Additional chief examiners were recruited to meet the increase in testing and ease the burden on the initially appointed chief examiners. These examiners1 were recruited from among ordinary examiners who had demonstrated the ability to control and organise testing. 44. The validity of certificates issued is ensured since all tests are criteria-referenced, the standards being the criteria. No attempt is made to compare the performances of different candidates, each candidate's test performance being related to the performance called for in the trade standards. A typical trade test paper and marking scheme forms Annex V. 45. All marking has been made as objective as possible and unique to the Malaysian practical testing system are the distinctions made in marking critical and non-critical items. All practical tests contain critical items and non-critical items, as illustrated below. (a) Motor vehicle test - basic level (as set out in Annex VI) Critical items: the starting of an engine after fault finding and/or adjustment; the setting of spark plug gaps within given limits; the setting of tappets within given limits. Non-critical items: filing sguare and flat; giving verbal reports on the condition of components. » All the additional chief examiners were from the Kuala Lumpur area. This was to ensure their ability to attend frequent panel meetings convened by the technical unit. £-1528-2:33 - 9(b) Ei§£t£iciansJ[._test_^_^a§ic_level C£iti£al_it§is: - correct polarity; correct earthing. Non-critical items: neatness of cleating; wiring length. 46. All critical items are so indicated in the test questions and brought to the attention of candidates. These critical items are rigidly assessed as being "acceptable" or "unacceptable" whilst non-critical items are marked conventionally on a three-point scale. TO be successful, candidatesfflusthave all critical items assessed as "acceptable" and obtain 50 per.cent of the total marks possible for the non-critical items. Test format and procedure 47. For theory tests, two formats have been established: one for the oral tests at basic level and one for the written tests at intermediate level. For the oral tests, lists of guestions have been developed and grouped into sections with answers provided. The oral examiner is trained to promote an informal atmosphere to eliminate nervous tension during the oral examination and to: (i) (ii) ask each candidate a fixed number of questions from each exercising his own discretion as to the choice of questions; section, conduct the test in either Malay or English according to the candidate's preference and to word his questions in a way which ensures understanding. All tests at intermediate level consist of objective questions which are primarily of the multiple-choice type. An example of the intermediate test is presented in Annex VII. 48. Tests have been prepared at basic level for all trades (excepting that of commercial driver, for which there is no demand) for which standards have been approved, and for 12 trades at intermediate level. 49. The Technical Unit organised many debates with representatives of the training agencies, members of the standard-setting committees and examiners to define the policy regarding the importance of the time factor in practical testing. Following these discussions, the chief examiner was authorised to exceed the time limit stipulated in the basic-level test paper. In awarding extra time, consideration is given to the existing test facilities, the availability of tools and equipment and evidence that the candidates, given extra time, have the ability to complete the test successfully. During the latter part of the project there has been, however, a growing demand for a more rigid approach to the tine factor since it is felt that realistic time norms for all tests have now been established based on experience, and the fact that the facilities, equipment and training have in most centres been geared to meet the test requirements. 50. A^l tests have been conducted over weekends. Even with the extension of testing, this was found possible and enabled examiners from industry to participate with a minimum of interference to normal training in training institutes or to production when the tests were held in industrial establishments. 51. Even though payments to examiners for travel, subsistence and examination duties have been minimal, it has not inhibited the recruitment of examiners at any level, as evidenced by the fact that senior executives and company directors have lent their services at many tests. 52.

The the Technical delays in the certificates to 1973 pilot tests revealed deficiencies in Unit, test panels and training agencies. marking of test pieces, in ratifying successful candidates. information feedback to There were also excessive results and in issuing 54. To counteract the problems which emerged during following measures were taken: the pilot tests, the (i) All examiners were made responsible for writing a report on the tests they supervised. The report was to include comments on organisation, facilities, general strengths and weaknesses, and recommendations. (ii) Training agencies were encouraged to ensure that their instructors were present when the tests were conducted. They were allowed to move freely among their students whilst tests were being conducted to personally observe strengths and weaknesses. A dialogue was organised among the Technical Unit staff, 6 chief examiners and 28 staff of the major training organisations to exchange ideas, cite problems and propose solutions. (iii) Test marking was speeded up and, wherever possible, decentralised to the actual test centre; only certain specimens were brought back tc headquarters for subsequent trade test panel examination. The convening of trade test panels to approve results and arbitrate on borderline cases was expedited. While this has brought a significant improvement, delays still occurred in issuing results and awarding certificates since: (a) the final approval of results was vested in the Board, which meets infrequently - at most four times a year; (b) for publicity purposes, all certificates were being issued at an annual ceremony presided over by the Minister of Labour and Manpower. 55. In 1975, the system was again reviewed which are currently in operation, introduced: (i) (ii) and the chief examiners issue a comprehensive tests they are responsible for; the following confidential a member of the Technical Unit, who is present written confidential reports on examiners; at all procedures, report on all tests, submits (iii) instructors are encouraged to attend and witness all tests that their own students undertake, but are subject to the control of the Technical Unit staff who are present to prevent interference with the actual testing and marking process; (iv) all tests, with the exception of those involving fitting, turning and machining, are marked on the spot by the examiners and the results known within hours after the tests are completed; (v) immediately following the marking, a dialogue takes place between appropriate training staff, examiners and Technical Unit staff; the (vi) test pieces for fitting, turning and machining are of relatively small size and are returned to Kuala Lumpur for testing in an industrial establishment; the results from such tests are available within two weeks; (vii) successful candidates are notified immediately after both the trade test panels and the CTSTC have approved the results; however, two month delays in notification still occur. E-1528-2:33 - 11 - Additional related activities The testing of apprentices 56. The Technical Unit has conducted annual tests for apprentices completing a four-year apprentice training conducted by the Ministry of Labour and Manpower. This is referred to in Annex VII under "Related activities". 57. These tests, which reguire the setting up of special panels and the setting, on average, of 45 different test papers covering 15 trades, have occupied the entire technical staff of the trade testing section for a minimum of two months per year. 58. Representations have been made to investigate the apprentice testing system which, since it is at variance with the national standards, trade testing and certification system, results in overlapping and confusion, and demands an inordinate amount of time for minimal numbers of candidates from an overtaxed, understaffed Technical Unit. 21i§_.2Igr;all_deveio£fient_of_tfee_t£ade §£aada£S§i-£^tiaa_a&i_£SEiifi£ati2a_si§iM Ssaetai 59. During the life of the project, even with the shortage of staff, significant quantitative achievements have been made, as set forth in Annex II. 60. Qualitative growth and recognition is illustrated by the fact that there has been, and is, a demand from private candidates (who are under no compulsion to do so) for the standard certification tests and their numbers have grown from zero to 343 during the project. 61. Significant changes in attitude have occurred, generated by and effective implementation, as illustrated in the following examples: persuasion (i) Two large companies in the private sector, namely the Dunlop Rubber Company and the Malaysian Tobacco Company, have encouraged their employees to take the tests, offered facilities and equipment for testing, and financially rewarded successful employees. (ii) The national training agency (MARA), with a large degree of autonomy, has changed its attitude of aloofness to one of wholehearted support, to the mutual benefit of both entities. (iii) Two agencies* which are setting up or expanding training facilities have sought the advice and assistance of the standards, testing and certification section and plan to co-operate in common areas, aligning their training to meet the requirements of the NITTCB. syllabi 62. Syllabi have been developed for all standards promulgated, following the standard format as illustrated in Annexes X and XI. Those for basic and intermediate grades for refrigeration and air-conditioning mechanics appear as Annexes VIII and IX. The syllabi have been established by committees consisting of: instructors, as representatives of the training agencies; representatives from the standard-setting committees, to thought and clarify doubts regarding depth of subject; give continuity of members of the Technical Unit. 63. It is not mandatory for training agencies to follow an established syllabus, which allows latitude for experimentation and course enrichment by individual training institutes. 1 The Agro Industrial Training Complex Kuala Pilah - joint venture between the National Onion of Plantation Workers, the State Government and the Lutheran Church.

A limited survey on the employment status of certificate holders was made by the Technical Unit. Although its validity was questioned by a subsequent project tripartite review, it gave rise to recommendations regarding methods of promoting a greater understanding of the NITTCB and its activities from which the following action resulted. In collaboration with the National Film Unit of the Ministry of Information, a trailer film depicting the activities of the public training institutions and the role of the NITTCB in the national trade standards, trade testing and certification programme has been produced and shown on TV. Production of a feature film is under active consideration. The Honourable Minister of Labour and Manpower has held discussions with senior management personnel of the industrial sector to obtain their co-operation in the employment of NITTCB certificate holders. 65. The Technical Unit has carried out a limited programme of visits to industries for discussions with personnel and production managers regarding the national industrial training programme and the trained resources available through the trade testing programme. 66. The Technical Unit has contacted organisations such as the Malaysian Institute of Management, the Federation of Malaysian Manufacturers, the National Productivity Council and the Malaysian Employers' Consultative Assocation and persuaded them to disseminate information through their circulars to their members, and requested permission for technical staff to participate in any seminars arranged. 67. The Technical Unit has established contact with the Directors of Labour in each State in order to compile and maintain a catalogue of industries, for use in circulating the NITTCB Newsletter and publicising NITTCB activities. 68. The Technical Unit has commenced a series of monthly meetings of the senior officials of the Technical Unit and other department heads of the Ministry of Labour and Manpower to identify problems associated with the employment of certificate holders and to formulate remedial action.

The very selection of trades for which s t a n d a r d s are set is of utmost importance, and experience has proven that standards developed on the basis of recognised needs have been supported while those developed without adeguate supporting evidence of need have not been utilised. Since the resources of the Technical Unit are limited and the production of trade standards is time consulting, it is strongly. recopmepdeg that only those standards be produced for which a firm demand and subseguent support have been established. 71. The standards in their present form allow for a degree of flexibility in that the individual tradesman is free to take tests in different trades at differing levels. There is in Malaysia, however, a demand for persons with a relatively broad base of skills but a limited number of in-depth s k i l l s . Trade s t a n d a r d s and tests at basic level could be utilised for the broad-based training, but it_is_rec.gmmended that subseguent certification be geared to progressive testing in line with training modules of employable skills, and that the issue of certificates be geared to presenting individual skill p r o f i l e s . Testing 72. The practice by which industry controls the setting and marking of all tests has proved viable, and the voluntary co-operation of all sectors of industry has been outstanding. Even though a large cadre of trade examiners has been built up, it is recommended that a continual recruitment of examiners be carried out in order to. provide a good geographical and ethnic spread and to distribute equitably the demands made on industrial organisations. 73. Trade testing at basic level will continue to increase with the i n c r e a s e in the numbers of people being trained by the training agencies and in the growth in the number of applicants from industry. Even so, the present system will remain viable, provided that training agencies which demonstrate a capability to consistently a c h i e v e good test results are accredited for conducting their own tests. 7t». It is recommended that the following implementing accreditation be applied: requirements and procedures for (a) a training section or department should have achieved and maintained an 80 per cent pass rate over a series of three consecutive tests; (b) an accredited training section or department should then be allowed to conduct its own testing programme which could be either based on progressive tests or end tests; (c) the NITTCB would award certificates to students whom accredited agencies judge have met the standards; (d) control should s t i l l remain with the NITTCB, which would retain i t s right to impose its own tests at any time in order to ensure that the standards are being maintained by the accredited training agency. 75. In addition to maintaining the validity of the present system, accreditation would promote a healthy competition among d e p a r t m e n t s of an institute and between developing institutes and a g e n c i e s , thus reducing the cost of testing. (E2t§: Inherent in the system of accreditation is a need for the Technical Unit to provide an advisory service on designing and conducting progressive and end tests.) 7 6. The marking of test pieces is now efficient since, with the exception of fitting and metal machining test pieces, they are all marked in situ under the supervision and security of the Technical Unit immediately after the tests are E-1528-2:33 -Incompleted. The fitting and metal machining test pieces are currently marked in industry outside the security control of the Technical Unit; it_is_therefore r.ecomjnended that the proposal made by the expert and agreed to in principle by "the Director of the Technical Unit regarding the setting up of a gauge room for checking such test pieces on its own premises be implemented. Certification 77. It is essential that candidates who pass the basic tests receive notification of the results at the earliest possible date, since a large majority of them are job seekers and the immediate possession of a pass certificate would be advantageous in finding employment. To ensure this, it.is .recommended that: (a) the Director of the Technical Unit be authorised to forward to successful candidates an official result notification valid for one month within one week of the test's being completed; (b) official certificates be issued to successful candidates within one the test completion. month of During the life of the project, there has been a growing demand from workers in industry, many of whom have had no formal training but who have learned their skills "on the job", to take the certification tests. Private candidates who have taken the tests number 343 to date, and with increasing publicity this demand ir increasing. The pass rate for such candidates is 40 per cent. 78. This motivating of people to improve themselves by updating and broadening their skills, thus giving them greater mobility in the labour market, is most encouraging. Many of them face certain problems, i.e.: (i) Some skills needed for passing the tests have not been acquired because, at their particular place of employment, certain skills may not be reguired, nor the relevant equipment available. (ii) Particularly in the great majority of small companies, there is no training structure so that employees who may be efficient in the skills of their trade will not have been exposed to the related theory. There are no facilities to remedy this at present apart from a few whose standards are suspect and under no control. private schools 79. It is recommended that, for these people, the standards be broken down into modules of training; and it_is_further_recommended that these training modules be offered at the existing 13 vocational schools, which are eguipped for engineering and building courses, and the 10 training institutes, which are currently training students for NITTCB tests. The classes would be held in the evenings on a part-time basis and during school vacations. This is feasible, as the vocational schools operate for only 38 weeks a year and the training institutes for approximately 44 weeks. No evening courses are currently held, nor does training now take place on the two-day weekends. The costly capital equipment could thus be utilised more, and instructors could be a blend of normal staff on overtime plus specialists from industry. Staffing of.the.Technical Unit 80. The failure to recruit and phase in technical staff with the appropriate background and experience for the Technical Unit has inhibited development and may impair the progress already made. The qualifications called for in the Project Document for co-ordinators have not always been respected in recruiting; 8 of the 11 technical staff recruited in April 1975 have, after receiving a basic training in the duties of the Technical Unit, resigned because their job responsibilities did not match their abilities, training and aspirations. The net gain in technical staff at the operational level during the life of the project has only been three. Based on experience and the existing situation, it_is_recommended that: (a) in the short term, the Unit should confine itself to on-going activities, namely standard setting, testing, certification and curriculum development; E-1528-2:33 - 15 - (b) staff recruiting should be based on two categories: (i) (ii) permanent staff appointments consisting of persons matching, as near possible, the original job description; as staff from the training agencies seconded to the Technical Unit on a two-year cycle. This would provide an immediate response to technical staff deficiencies and promote a cross-fertilization of understanding between the Technical Unit of the Board and the training agencies. General Apprenticeship 81. The Board i s now involved in two forms of testing and certification: (a) one is geared to the national trade standards for which training agencies and from industry are eligible; candidates from §11 (b) the other is geared exclusively to apprenticeship, which lies within the purview of the training department of the Ministry of Labour and Manpower. 82. This uncorrelated dual certification by the NITTCB causes confusion among employers and misunderstandings with other training agencies. To rectify this situation, it is recommended that: (a) the agency conducting apprentice training issue its own certificate relating to the successful completion of an apprentice course; this is in line with the right of all other training agencies to offer internal c e r t i f i c a t e s ; (b) apprentices w h o want to obtain a n NITTCB certificate take the same test and be subject to the same criteria as candidates from industry and other training agencies. The over-all results to date of !§§!ios_a.a£_£§££i£i£&Ii2a 83. The practice by which industry representatives define the standards setting and mark the tests have proved viable and is now well supported by all the training agencies. The catalytic effect on training is evidenced in the improved results at training agencies which, with one exception, have been able to gear their training to meet the standards. 84. The exception is that of the vocational schools, which have been to do sc because: unable (a) the role of the vocational schools has not been clearly defined; (b) the schools attempt to cater to both students who will proceed further academically . and to those who will enter industry equipped with a particular range of basic skills; (c) the standard course in the vocational schools is of two y e a r s ' duration and the established examination to which, primarily, tuition is geared is the vocational schools certificate. The examination for this certificate, unlike the NITTCB certificate, is norm-referenced (the normal curve of distribution is used to determine success) and its award is dependent on both academic and broad skill attainment. 85. A series of discussions is currently taking place between members of the Board and vocational education authorities to establish the common elements which exist between NITTCB tests and vocational school examinations, in order to discover what modifications are required in the system of training and subsequently to equip some vocational school students to successfully take the national standard certificate tests. 86. It_is recommended that every effort be made to define objectively the role of the vocational schools and that consideration be given to the two following alternative suggestions: E-1528-2:33 - 16 - (a) After the first year, in which all students take the same course, two streams should be formed: one would be predominantly academic and technical and geared to a further polytechnic-type of education, and the other predominantly craft-based, geared to preparation for NITTCB certification; or alternatively (b) if the present system is to be continued, provisions might be made for the schools' accreditation for NITTCB theory tests and arrangements made for a short "topping-off" skill training course in industrial training institutes. Thus, students with the aptitude and inclination to become craftsmen could take NITTCB certification tests. Publicity, 87. Although there is evidence that NITTCB standards, tests and certification are becoming widely recognised by industry throughout Malaysia, many employers and employees are still uninformed about their existence. 88. Advertisements appear regularly in newspapers; a one-minute trailer dealing with standards, testing, certification and training courses is broadcast nightly on the national television network. This was designed by the Technical Dnit, which is now negotiating a feature film. 89. While it is important that the scheme should be national in all respects, it is also important that a growth in its recognition and subsequent growth in demand be matched by a growth in the organisation and staff of the Technical Unit. With the present limited staffing, there is a danger that any increase in publicity will bring an overwhelming demand for testing. It is recommended that this consideration be given weight when formulating policy governing future publicity.

The Trade Standards result from the co-operation and involvement of representatives of industry, working in trade committees, and are directly related to the skills, equipment, tools and materials in common use, in Malaysia, at the present time. 2. The Trade Standards herein relate to occupations mentioned in the Malaysian Dictionary of Occupational Classifications unless otherwise stated. 3. level. The Trade Standards referred to relate specifically to workers at craft 4. All the Trade Standards are set out in a standard form and for each grade performance requirements, knowledge requirements and tools and equipment to be used are listed. 5. All Trade Standards will be subject to a periodic review and modified as required. 6. Certificates will be awarded, for each grade, to candidates who successfully pass the requisite qualifying trade test. INDUSTRIAL TRADE CERTIFICATION GRADES 1. For each trade, unless otherwise specified, there are three grades. They are: (i) (ii) (iii) The Basic Grade; The Intermediate Grade; The Advanced Grade. 2. The Basic Grade relates to the level of knowledge and skill of a beginning craftsman. This level should be attainable by graduates of approved training courses or those who have had a minimum of 2 years "on-the-job" experience. 3. The Advanced Grade is based on the highest level of a craftsman, in that trade, in industry. 4. The Intermediate Grade falls approximately midway between the Advanced Grade and the Basic Grade. .THE FORMAT OF TRADE CERTIFICATION TESTS 1. For all grades, of certification there will be practical skill tests and related knowledge tests .-• 2. All tests will be based on the Industrial Trade Standards. 3. Candidates taking higher tests are expected to know items required for the lower tests, e.g., a candidate for Advanced Grade must be able to fulfil all the . - 26 - requirements for the Basic Grade, the Intermediate Srade^and the Advanced Grade. Tests will reflect this requirement. 4. The duration of practical tests will vary according to trade and according to the certification grade. 5. For the Basic Grade the related knowledge test will be oral. test questions will he related to the following three sections: (a) safety; (b) tools and equipment - identification and selection; (c) the practical test given. The oral 6. There will be written tests, based on objective-type questions, for both Intermediate and Advanced Grades, in addition to oral questions which may be asked. 7. The emphasis in all certification tests will be on objectivity and the requirements of industry. ENTRANCE CRITERIA FOR TRADE CERTIFICATION TESTS' 1. There is no stipulated educational qualification but it may be difficult for candidates with a poor background of education to pass a Certificate Trade Test in the higher grades. 2. Basic Grade candidates must: (a) be over 17 years of age; ing establishment; and (b) (i) (ii) 3. or be over 15 years of age if in an approved train- have a minimum of two years' "on-the-job" trade experience; have completed the minimum requirements of the Basic Grade Syllabus in an approved training course. Intermediate Grade candidates must: (a) possess the Basic Grade Certificate; (b) (i) (ii) 4. or and have had a minimum of 2 years' subsequent "on-the-job" trade experience; or have completed the minimum requirements of the Intermediate Grade Syllabus in an approved training course. Advanced Grade candidates must: (a) be over 21 years of age; and (b) possess an Intermediate Grade Certificate; (r) have had a minimum of 2 years' subsequent "on-the-job" trade experience. and 5. Candidates possessing the necessary skill and qualifications can apply for trade tests in more than one trade. APPLICATIONS TO TAKE TRADE CERTIFICATION TESTS 1. Candidates for tests and certification should be nominated by respective employers using the official application form obtainable from: Setiausaha Kerja, Lembaga Latihan Perindustrian dan Persijilan Ketukangan Kebangsaan, Bangunan Campbell Komplek (Tkt.18), Jalan Campbell, Kuala Lumpur 01-09. - 27 - 2. The principals of approved training institutes will be considered as equivalent to employers for candidates applying for the tests. 3. Candidates who are not currently in employment but are otherwise eligible can also apply to sit for tests provided they are able to produce evidence that they can meet the entrance criteria. 4. In cases where individuals are refused nomination by their employers they will be allowed to appeal to the Board. Entry fees Details concerning entry fees for the trade certification tests, will be as prescribed by the Board from time to time. The conducting of tests 1. All tests will be conducted by personnel approved by the National Industrial Training and Trade Certification Board and the Board will possess the right to send its own representative(s) to observe and inspect any tests being carried out on its behalf. 2. There will not be a fixed schedule for holding tests. tests will depend on the demand and the facilities available. The frequency of The marking of tests 1. basis. All oral and written tests will be assessed on a conventional mark-awarding i 2. Parts of practical tests may be assessed on a conventional mark-awarding basis but certain skills,, considered critical to a particular level, will be marked either "acceptable" of "unacceptable". Candidates giving an unacceptable performance in one of these critical skills will automatically fail the complete test.. Candidates failing tests 1. Candidates who take a test and fail, will be eligible to sit for a further test after a period of six.months. 2. Candidates who fail a test may re-sit for the next test by showing the result slip without obtaining a further endorsement from the employer and/or principal. 3.

The syllabus reflects the training programme recommended to cover the requirements for reaching the relevant Trade Standard determined by the NITTCB and should be read in conjunction with that document. It is to be noted that the time needed to cover the syllabus will vary according to the aptitude, academic level and industrial experience of the trainees, to the workshop facilities and workplaces available, to whether the course is intended to be a terminal one or as the first stage of an ongoing process, e.g. as in apprenticeship, to whether the curriculum covers one or more trade subjects, and above all to the percentage of training time that is to be devoted to practical work. In translating the syllabus into a training programme or course of study, therefore, the above considerations will determine how much of the related theory listed will be taught at each stage, and to what depth. This will vary from a simple statement or demonstration of the theoretical point to a careful analysis of the principle and its implications in practice: for example the properties of the various metals used in the occupation. Similarly with calculations and trade drawing, the syllabus indicates only those items considered essential to do, or to understand, the job in hand, and makes no reference to practice in calculations or in drawing. All the emphasis is on the practical skills. The criterion for determining the time to be allotted to workshop activities is of course the time needed to acquire the skills involved. Since the major emphasis in the Trade Test is upon practical skills rather than theory it will obviously be necessary to devote the maximum time possible to workshop practice, which in turn pre-supposes sufficient equipment and workplaces and the instructional staff to make the best use of these. Although presented as a logical sequence of instructional content, this syllabus is not intended to dictate the order of instructional topics, nor does it indicate the methodology to be used. These will be influenced by practical considerations, but it is suggested that because of this, particular care should be taken to ensure that the training is based upon sound pedagogical principles. For example, for nil theoretical content, even if it is not always possible to handle this in the ideal form of "shop talks' as the need arises, the practical relevance of the topic or exercise will be explicitly established, such stimuli as judiciously chosen and carefully organised industrial visits will be provided for4, individual or group project work will be encouraged; when possible training 'exercises' will lead, cumulatively, to the production of a useful endproduct . Specific reference is made early in the syllabus to safety. It is expected that while particular attention to safety factors will be given at the beginning of the course there will be continual reference to safe working practice throughout. This syllabus, like those for the other two grades and for all trade areas, will be subject to an ongoing process of continuous evaluation and review based upon feedback from industry and from training institutions, together with the results of trade testing by the NITTCB. NOTE: The numbers placed at the right of both left and right-hand columns are references to the appropriate items in the Trade Standard. -78 - REFRIGERATION AND AIR-CONDITIONING MECHANIC BASIC GRADE I.

Basic gas welding (in f l a t p o s i t i o n ) . 102 - 93 F O R W A R D This NITTCB syllubus, reflecting the Intermediate Grade.Trade Standard, is the result of active collaboration between the national governmental training agencies concerned with craft training, assisted by training officers from the private sector. Like the syllabi for the Basic and Advanced grades, it will be subject to an on-going process of continuous evaluation and review based upon feedback from industry and from training institutions, together with the results of trade testing by the NITTCB. In interpreting the syllabus, and in working out the training programme* based upon it, the same considerations apply as are set out in the Basic Grnde syllabus. It is to be noted, however, that although the primo emphasis is still upon the practical trade skills, the Trade Test at this level includes written answers to objective typo questions. Attention is also drawn to the provision in the Regulations that the Intermediate Grade test may include questions and exercises based on the Basic Grade syllabus; it may, therefore, be found desirable to include in the Intermediate Course some recapitulation or practice in Basic skills. It is anticipated that many if not tho majority of the candidates for Intermediate tests will be oraftsmen alroady omployed in industry and that many training agencies will offer up-grading courses specifically designed to prepare these candidates for the Test. In such circumstances, it is of course expected that this full syllabus will not be followed, but that a judicious selection based on the needs of the individual trainees will be made. NOTE:- (1) Constant emphasis should bo placed, as in the Basic Grade, upon SAFETY rules and regulations, safe working procedures and first aid. (2) The numbers placed at the right of both loft and right-hand columns are roforence to the appropriate items in the Trade Standard. - 94 - I.
