 WSQ is based on industry agreed national skills standards, and courses only cover skills training which is determined by employers to be relevant to prevailing occupations in the industry.WSQ training is quality assured by then Singapore Workforce Development Agency (WDA; now Workforce Singapore) and is delivered to suit adult workers - modular, flexible, not necessarily classroom based and recognises past skills and experience that workers already acquired.WSQ was launched by then Minister of Manpower Ng Eng Hen on 27 October 2005.
