These are figures compiled by the Government of Aragon from the 2025 PISA report, showing how the distribution of students has changed over the past decade. Specifically, in Mathematics, 17.1% of Aragonese students were at Level 1 in 2015; three years later, the figure had risen to 19.7%, and in 2022 it reached 22.1%. Now, in 2025, it has risen to 32.3%. In other words, the percentage has increased by 15.2 percentage points in ten years and has practically doubled.
The increase in the number of students at the lowest level can also be seen in the other skills assessed. In Reading, 28.6% are at Level 1, more than double the 14.2% recorded in 2015. In Science, the percentage currently stands at 23.1%, compared with 14.2% a decade ago.
VERY FEW STUDENTS ACHIEVE EXCELLENCE
At the opposite end of the scale, very few Aragonese students reach the highest performance level. Only 0.6% of students achieve Level 6 in Mathematics, while in Reading the figure falls to just 0.2%. In Science, only 0.3% reach this level.
Looking at the second-highest level, Level 5, only 4.3% of Aragonese students are at these levels in Mathematics. The proportion falls to 2.8% in Reading, while in Science it stands at 4.4%. In the latter subject, Aragon also remains below international benchmarks, as around 7% of students in the OECD and the European Union reach Levels 5 and 6.
The trend over the past decade also reflects a reduction in the number of students at the highest levels. In Mathematics, Levels 5 and 6 accounted for 9.3% of Aragonese students in 2015, compared with 4.9% today. In Reading, the figure has fallen from 7.5% to 2.8% and, in Science, from 6.6% to 4.4%. As the percentage of students at Level 1 increases, the presence of students in the highest-performing bands is declining.
