France's PISA 2025 results worst on record; GDP risk of €150B by 2050

French students' PISA 2025 scores hit their lowest since the rankings began in 2000, prompting a projection that without improvement, France's GDP could shrink by €150 billion by 2050. The claim is based on a modeling estimate, not a direct measurement, and the causal link between test scores and GDP is uncertain. This matters because it could pressure French education policy and long-term growth outlook.
