The Organisation for Economic Co-operation and Development (OECD) has raised concerns over a “continued decline” in the Program for International Student Assessment (PISA) test results worldwide. Spain’s students have experienced a particularly sharp drop, achieving their worst-ever scores in both mathematics and reading. This setback isn’t isolated to Spain; even high-performing nations like Japan, Korea, and Estonia have also seen declines. The PISA report highlights a worrying trend in educational standards across the developed world. Experts attribute the decrease to disruptions caused by the COVID-19 pandemic and evolving learning challenges. The OECD is urging countries, including Spain, to address these issues and implement strategies to improve student outcomes and reverse this negative trajectory. These results signal a need for urgent educational reforms in Spain and internationally.
