This document was drafted for ESF+ managing authorities, intermediate bodies, and non-governmental organizations (NGO). It presents information on concepts, tools, and practices which can support stakeholders in using European Social Fund Plus (ESF+) resources to support the quality, availability and efficiency of work-based learning and apprenticeships and enhance employer engagement. Work-based learning and apprenticeships takes place at two learning venues: schools and the workplace. This document emphasizes the need of close collaboration between both sectors and underlines the role of ESF+ in developing processes and partnerships. Managing authorities and intermediate bodies are encouraged to enable strategic responses to calls for proposals e.g., through stakeholders’ consortia representing the two learning venues.
