Career path: On successful completion of the trade test, the candidate will receive a national trade test certificate and is regarded as a qualified artisan.
Overview: The Section 26D trade test (named after the relevant section in the Manpower Training Act) is a way of recognising the prior learning and experience of a person who has been working for some years in a particular trade but has not passed a trade test and is therefore not recognised as a qualified artisan. After the applicant’s suitability for a trade test is determined, the applicant will then undergo a trade test.
