How widespread is student disaffection with school in different education systems? What policies and practices are most effective in fostering students’ sense of belonging and participation in school? These questions are of great concern to educators in many countries, not only because of the interrelationship between student engagement at school and learning outcomes, but also because student engagement represents a valued outcome in itself. The OECD PISA provides not only information on students’ literacy skills, but also on their attitudes and values, their social backgrounds, and on important features of the schools they attend.
