„The research shows that activities that take place before and after formal school hours, such as breakfast schemes, and sports and arts clubs, generally yield positive outcomes for learners and can support children at risk of academic, emotional or behavioural interventions.”

„Participation in after-school extracurricular activities generally results in higher levels of academic achievement, school belongingness and intrinsic motivation among students from various ethnic backgrounds. Extracurricular activities may be especially helpful for students from underprivileged populations.“

„PISA 2018 showed that students who were enrolled in schools offering more creative extracurricular activities performed better in reading, on average across OECD countries and in 32 countries and economies, after accounting for students’ and schools’ socio-economic profile.“

„Doing extracurricular activities with students is not only beneficial for teacher-student relationships but can also improve the disciplinary climate. Our findings show that the more time teachers spend on extracurricular activities, the more students report that the classroom is disciplined.“
OECD (Hrsg.), Teaching in Focus 39 (April 2021), S. 4.

„Teachers’ involvement in extracurricular activities with their students might be an effective way to improve the disciplinary climate. Time spent with students outside of the regular classroom hours can be particularly positive for establishing and nurturing good relationships with students, which, in turn, are conducive of good conditions for students’ cognitive and social-emotional development.“
OECD, Positive, High‑achieving Students (2021), S. 27.

„As the existing research literature suggests, adding time at school (especially instruction time) has different effects for different students. Providing a rich array of activities geared to the specific needs of different students, including those at risk of low performance, seems an approach worth exploring (e.g. remedial lessons, enrichment programmes, outdoor and real world experiences).“

„Students who were enrolled in schools that offer more creative extracurricular activities (including music and art activities) performed better in reading, on average across OECD countries (by 4 score points) and in 32 countries and economies, after accounting for students’ and schools’ socio-economic profile. […] Countries and economies whose schools offer more creative extracurricular activities tended to show greater equity in student performance.“

„Offering additional lessons on curricular subjects after regular hours at school is a common practice across PISA-participating countries and economies. These activities typically aim to reinforce or enrich instruction and learning that has taken place during regular school hours.“

„The resources of private schools enable them to offer a broader curriculum with more optional subjects, including, for example, more opportunities to study languages of one’s choice, ancient and modern.“

„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.“

„In England, the pupil teacher ratio in the state sector was 17:1 in 2016 compared to 8.6:1 in the private sector. In practice this means children receive more individual attention, more pastoral support and smaller class sizes. Children from independent schools also typically enjoy a wider range of extra-curricular opportunities than those educated in the state sector. Attending an independent school brings disproportionate privileges in terms of exam results, prestige of position in the labour market, and income.“

„In schools where the number of extracurricular activities is higher students tend to report a better school climate.“

„The relationship between extracurricular activity involvement and substance use generally appears to be negative (less substance use) even during a time in development when substance use tends to increase, except for the case of athletic participation.“
