As the global benchmark in educational assessments, PISA results are always hotly anticipated. The eighth round of PISA assessment was originally planned to take place in 2021 but the disruption caused by COVID-19 forced the assessment to be postponed by a year. The first results of PISA 2022...

Immigrant students who share a common country of origin, and therefore many cultural similarities, perform very differently across school systems. The difference in performance between immigrant students and non-immigrant students of similar socio-economic status is smaller in school systems...

Equity is a fundamental value and guiding principle of education policy and practice, but it is not necessarily actualised in schools and education systems around the world. There are large variations across PISA-participating countries and economies in the magnitude of the difference that...

School systems handle the challenges of diverse student populations in different ways. Some countries have non-selective and comprehensive school systems that seek to provide all students with similar opportunities, leaving it to individual schools and teachers to meet the particular needs of...

While most 15-year-old students spend part of their after-school time doing homework, the amount of time they spend on it shrank between 2003 and 2012. Socio-economically advantaged students and students who attend socio-economically advantaged schools tend to spend more time doing homework....

Every three years, when PISA results are published, the world’s media focuses on countries’ rankings in mathematics, reading and science performance. Often, what is lost in the subsequent national-level soulsearching about how to improve student performance is the fact that many countries...

While PISA reveals large gender differences in reading, in favour of 15-year-old girls, the gap is narrower when digital reading skills are tested. Indeed, the Survey of Adult Skills suggests that there are no significant gender differences in digital literacy proficiency among 16-29 year-olds....

Some 65% of socio-economically advantaged students reported that they know well or have often heard of the concept of quadratic function, on average across OECD countries; but only 43% of disadvantaged students so reported. On average across OECD countries, the 20% of students who are most...

Immigrant students often have to overcome multiple barriers at once in order to succeed at school. Across most OECD countries, poor performance among immigrant students relative to other students is strongly related to social disadvantage at school, as reflected in the proportion of students...

PISA 2015 data show that, on average across OECD countries, as many as three out of four students from the lowest quarter of socio-economic status reach, at best, only the baseline level of proficiency (Level 2) in reading, mathematics or science. While in Canada, Denmark, Estonia, Finland,...
