This article shows the result of an international project from the European Commission, and it aimed to analyse 30 cases of effective European entities in the field of adult education, from Poland, Spain, Finland and Italy. The objective was to collect the best strategies that generate good employment and social inclusion results. The research analyses the methodologies of official educational corporations, such as vocational training centres and schools for adults; and for the first time, the research addresses the training carried out by companies. The methodology focuses on case studies, using the observation list as the main instrument. The sample is an intentional selection of entities with important training activities in different industrial sectors and positively impacting employment. The findings highlight relevant strategies, such as the importance of the educational scenario, the development of new personal and social skills, a flexible, individualised, and attractive approach in the teaching scope, and the importance of practical learning. Among the findings, new training paths are observed within the labour context, with innovative and revolutionary practices for the traditional school. The results also impact teacher training and education science faculties, that can incorporate new educational methodologies, with proven success in the labour market.
