Non-formal and informal learning (NFIL) practices, as well as the possibility of NFIL recognition and validation, can benefit a wide range of social groups, in particular the most vulnerable, and contribute towards correcting educational inequalities. This book presents and updates the contents of a project conducted by a team from Groupe ALPHA for the European Trade Union Confederation (ETUC) on NFIL practices and challenges in the EU, including a direct survey of ten Member States.
