(Part II) Students’ skills

But graduation rates, while important, speak little to the quality of education received. The OECD’s Programme for International Student Assessment (PISA) reviews the extent to which students near the end of their compulsory education (usually around age 15) have acquired some of the knowledge and skills that are essential for full participation in modern societies, particularly in reading, mathematics and science.

In 2018, PISA tested students from 79 countries, including OECD countries, Brazil, the Russian Federation and South Africa. The students were tested on their reading ability, their skills in maths and level in sciences. Research shows that these skills are more reliable predictors of economic and social well-being than the number of years spent in school or in post -formal education. The average student in the OECD area scored 488. On average in the OECD, girls scored 491 compared with 485 for boys.

Estonia is the highest-performing OECD country, with average PISA scores of 526, followed by Japan and Korea with 520 points. The lowest performing OECD country, Colombia, has an average score of 406. This means that the gap between the highest and lowest performing OECD countries is 120 points.

The best-performing school systems manage to provide highquality education to all students. In Canada, Estonia, Finland and Ireland for example, students tend to perform well regardless of their social background. In Israel and Luxembourg however, the gap between the students with the lowest socio-economic background and the students with the highest socio-economic background reaches more than 120 points, suggesting students’ socio-economic background tends to have an impact on their results. On average across OECD countries, there is a widening 89-point difference in PISA scores between the students with the highest and lowest socio-economic background.
