Students who are disadvantaged or who are struggling with their learning need more rather than fewer opportunities to develop and leam. In addition, students’ absenteeism and lack of punctuality can have a disruptive effect on their classmates and their school. This can be particularly problematic for schools that have high proportions of students who demonstrate these behaviours. Across OECD countries, 26% of students reported that they had skipped at least one class, and 20% reported that they had skipped an entire day of school without authorisation in the two weeks before the PISA test.
