The performance of the students in the participating countries can be compared.
The results also give an idea of the extent to which the students are prepared for life after school and are therefore relevant in the context of lifelong learning.
PISA is policy orientated, with design and reporting methods determined by the need of governments to draw policy lessons.
The data collected through PISA assessment cycles make it possible to measure change in student performance over time.
PISA provides participating countries with fixed criteria and regular updates on how well their students perform according to those criteria.
Countries will have the opportunity to see the effects of educational reforms, and how change in educational outcomes compares to international benchmarks. The PISA findings may be used both by the Ministry and other educational leaders to optimize the (national) education policy.
