Flemish 15-Year-Olds' PISA Scores Decline in Key Subjects

  • The 2022 PISA results show Flemish 15-year-olds scored 489 points in mathematics, 479 in reading, and 491 in science, all above the OECD averages.
  • Despite being above the OECD average, Flanders experienced a significant decline in scores between 2018 and 2022, with reading falling by 19 points and mathematics by nearly 15 points.

Recent results from the Programme for International Student Assessment (PISA) indicate a continued decline in the performance of 15-year-old students in Flanders across mathematics, reading, and science. The PISA 2022 assessment, which focused on mathematics, revealed that Flemish students scored 489 points in mathematics, 479 in reading, and 491 in science. These scores remain above the OECD averages of 472 in mathematics, 476 in reading, and 485 in science.

However, a concerning trend of decreasing performance has been observed over recent years. Between the 2018 and 2022 PISA cycles, Flanders saw a notable drop in scores, with reading skills declining by 19 points and mathematics by nearly 15 points. This decline in mathematics is reportedly three times larger than any previous PISA-recorded change. Science scores also saw a decrease, falling from 498.773 in 2018 to 490.578 in 2022.

Experts note that this downward trend in reading and science has been evident for a decade, with mathematics remaining stable between 2003 and 2018 before its recent drop. The PISA 2022 results also highlighted an increase in the number of students who do not achieve a basic level of proficiency, with 5% of Flemish students not reaching this level in mathematics and 12% in science. This indicates a growing number of students struggling with fundamental skills. The results for Belgium are reported separately for the Flemish and French-speaking communities due to their distinct education systems.
