„Well-designed after-school programmes can make a considerable contribution to the educational and social development of young people, and to staying on in school. Attractive opportunities for young people to engage in sports, learn a musical instrument or get involved in handicraft and other practical activities can help build social and professional skills, while countering the risk of isolation. Empirical evidence confirms the positive effects of extracurricular activities on schooling outcomes and career prospects.“
