The Cedefop European Skills and Jobs Survey (ESJS) is the first European survey dedicated to collecting information on the match between employees’ skills and the skills needed for their jobs. The aim of the survey is to shed light on the development of European policies on initial and continuing vocational education and training and employment policies. More precisely, the survey looks at how employees’ qualifications and skills are matched (or not) to the changing skill, demands and complexity of their jobs as well as at the extent to which employees’ skills are developed and used at the workplace. It also investigates the capacity of initial (e.g. work-based learning) and continuing vocational training to mitigate skill mismatch. The main topics discussed are: - skill needs; - skill development; - skill mismatch; - dynamic changes in skill mismatch.
