Part I: Introduction

The Training Board The Automobile Training Board is a statutory body established in 1982 under

the Vocational Training Council Ordinance to be responsible for all matters pertaining to manpower training in the automobile industry. The Training Board has been entrusted by the Council with the task of implementing a voluntary trade testing and certification system for the principal trades in the industry.

Purpose of Trade Test The objectives of implementing a trade testing and certification system for the

automobile industry are as follows:

(a) to set standards for skilled workers, (b) to help industry in the selection of workers for skilled jobs, (c) to facilitate the acquisition of recognized qualification, in particular for

those who have not gone through any formal training, and enhanced the status of skilled workers, and

(d) to facilitate the establishment of skills hierarchy for career advancement of skilled workers.

Trade tests will be set at the level that would reflect the standard expected of a competent motorcycle mechanic.

This guidebook sets out the trade test details and application procedures. The latest version can be found on the Trade Test Registry web site. For more information, please contact:

Trade Test Registry Vocational Training Council 10/F, VTC Tower 27 Wood Road, Wanchai Hong Kong Enquiry : 2919 1599 Web : http://ttr.vtc.edu.hk

Part II: Trade Test Details

Trade Test Format Trade test will consist of a practical test and a trade knowledge test.

Candidates are required to pass both the practical test and the trade knowledge test so as to achieve an overall pass in the trade test.

Practical Test For the practical test, each candidate will be given practical assignments to

complete. The duration of a practical test is about 6 hours. The test comprises a series of assignments including 6 long tests and 8 short tests. Candidates are required to pass 4 long tests and 4 short tests in order to achieve an overall pass in the practical test. Practical test will normally be conducted at the Automobile Industry Training Centre of the Vocational Training Council. Its address is:

Level 2 Kwai Chung Training Centre Complex 13-19 San Kwai Street Kwai Chung New Territories Tel. No.: 2449 1310 Fax No.: 2487 0737

Trade Knowledge Test For the trade knowledge test, each candidate will take a written test

containing multiple choice questions. The duration of a trade knowledge test is one hour twenty minutes. Candidates are required to answer correctly at least half of the 80 multiple choice questions in order to pass. The trade knowledge test will normally be conducted at the Vocational Training Council Tower, 27 Wood Road, Wanchai, Hong Kong.

Test Fee Each candidate taking the test is required to pay a test fee which will not be

refunded unless the test is cancelled by the Automobile Training Board.

17 11/2009

Trade Test Syllabus A trade test syllabus is given in Appendix 1, sample questions and

assignments at Appendix 2 and Appendix 3 respectively.

Test Results Candidates will be informed of the results by post about 2 months after

completion of the practical test and trade theory test.

Review of Test Results If a candidate is dissatisfied with his/her test results, he/she may apply to the

Automobile Training Board for a review of the test results. Such application must be made in writing to the Chairman of the Automobile Training Board within 28 days after the issue of the test results, and must be accompanied by a checking fee. The fee paid will be refunded if the application is successful. Application should be sent to:

The Chairman Automobile Training Board Vocational Training Council 10/F, VTC Tower 27 Wood Road Wanchai Hong Kong

The Automobile Training Board’s decision on the test results shall be final and will be conveyed in writing to the candidates.

Complaints Any complaints related to the trade test should be addressed to the Chairman

of the Automobile Training Board.

Award of Certificate Candidates who have passed the trade knowledge test and the practical test,

either at the same sitting or at different sittings within a time span of 3 years, will be awarded a trade test certificate. Candidates who have passed either the trade knowledge test or the practical test will be issued a statement of result.
