The most recent round of the assessment, PISA 2015, focused on 15-year-olds’ science literacy, defined as “the ability to engage with science-related issues, and with the ideas of science, as a reflective citizen”. To succeed on the PISA science test, students had to display their mastery...

Students whose parents work in professional occupations generally outperform other students in mathematics, while students whose parents work in elementary occupations tend to underachieve compared to their peers. The strength of the relationship between parents’ occupations and student...

Most students enjoy orderly classrooms for their language-of-instruction lessons. Socio-economically disadvantaged students are less likely to enjoy orderly classrooms than advantaged students. Orderly classrooms – regardless of the school’s overall socio-economic profile – are related to...

One in eight students across OECD countries has repeated a grade at least once before the age of 15. Many countries reduced the rate of grade repetition between 2003 and 2012. One in five disadvantaged 15-year-olds has repeated a grade. Even among students with similar academic performance, the...
