PISA 2022 was the eighth round of the assessment since its launch in 2000. Every PISA test assesses students’ knowledge and skills in mathematics, science and reading, and focuses on one
of these subjects and provides a summary assessment of the other two. In 2022, the focus was on mathematics.
The test assesses 15-year-olds as this is the last point at which most children are still enrolled in formal education. All students are eligible to sit the PISA assessment, regardless of whether they study in public or private schools, in academic or vocational
settings, or in full-time or part-time education. Students are selected after a two-stage sampling procedure. First, a representative sample of at least 150 schools is chosen that considers factors such as rural or city location. Then, roughly 42 15-year-old students are randomly selected from each school to
sit the assessment. Most countries assess between 4 000 and 8 000 students. The samples are weighted to refl ect the total 15-year-old student population.
This strict sampling criteria are just one of the reasons why PISA has become the world’s premier yardstick for comparing quality, equity and effi ciency in learning outcomes across countries. By providing an opportunity for countries to learn from each
other, PISA has developed into an infl uential force for
education reform.
PISA has helped policy makers lower the cost of political action by backing diffi cult decisions with evidence – but it has also raised the political cost of inaction by exposing shortcomings in policy and practice. This aids the development of education systems that can deliver high-quality instruction, equitable learning opportunities for all and nurture student well-being.
This brochure summarises some of the initial findings from PISA 2022 and puts them into context. The full set of results can be accessed in several published volumes. In conjunction with this round of PISA, the
OECD has captured a wider range of cognitive, social
and emotional student outcomes as part of the new
PISA Happy Life Dashboard. The dashboard considers
nine pivotal aspects to student well-being including
engagement with school, openness to diversity,
psychological well-being, social relationships and
study-life balance.
