The municipalities Beverwijk, Heemskerk, Uitgeest and Velsen cooperate in the joint regulation "IJmond Werkt!" to fulfill the execution of the Dutch Sheltered Employment Act (Wsw) and an important part of the reintegration services within the framework of the Participation Act. The four municipalities and IJmond Werkt! would like to know whether the reintegration approach is effective and how it could be improved further. IROKO and SEOR will answer this question by examining the current labour market, the use of the reintegration budget, the effectiveness of the approach and the necessary conditions to further improve it.
