Key outcomes for Wales
(as taken from the Executive Summary)
Achievement in science
The average PISA science score for Wales in 2015 was 485. This is 20 points lower than the average in 2006 (505).
Achievement in mathematics
The average PISA mathematics score for Wales in 2015 was 478. The average score has fluctuated over the last decade, but is at a similar level in 2015 as it was in 2006 (484).
Achievement in reading
The average PISA reading score for Wales in 2015 was 477. This has remained stable since 2006 (481).
Although there are clear socio-economic differences in 15-year-olds’ PISA scores, socio-economic inequality is actually much lower in Wales than the rest of the UK, and compared to most other countries across the world. In Wales, the gap between pupils from the most and least advantaged 25 per cent of families in Wales is around 50 test points in science. This is much smaller than the average across industrialised countries (88 points). However, this small gap is at least partly driven by the comparatively weak academic performance of pupils from the most advantaged socio-economic backgrounds in Wales relative to their equally advantaged socio-economic peers in other industrialised countries.
