An EU benchmark was set, that the proportion of early school leavers should not be more than 10% by 2010 (European Commission, 2006). Only six of the twenty seven Member States had met this benchmark. The average early school leaving statistic in Europe is 18%. This is nearly the double the benchmark to be reached by 2010-“ a real challenge” underlined by the European Expert Network on Economics of Education (EENEE, June 2007). The situation is different from one country to another : in 2007, the proportion of youngsters 18-24 years having left early school was 39,2% for Portugal, 18% in Bulgaria ; 13,1% in France and 13% in the UK and 5,2% in Slovenia. School failure is a major cause of exclusion among youngsters. It is seldom to meet teenagers totally opposed to school. Most of the time they haven’t found their place. A way to combat early school leaving is to propose youngsters an alternative pedagogical approach based on a positive experience acquired outside school. A voluntary experience enables to acquire and/or develop skills and competences that could be most useful. Volunteering is part of non-formal and informal learning enhanced by the Copenhagen process. Among an association, youngsters apply theoretical knowledge learned at school, enrich their social network, acquire or develop skills and competences, exchange good practices in learning. The main aim of the Comenius project « Success at School through Volunteering » is to propose youngsters leaving in difficult areas a pedagogical approach to enhance a voluntary involvement to succeed at school. The SAS project develops pedagogical sessions in order for youngsters value learning acquired through volunteering, to build a path between learning acquired through a volunteering and traditional learning at school. These sessions are supported by a pedagogical mentoring in order for pupils to be aware of their potential, to value the non-formal and informal learning and find a way back to school.
