¿Han empeorado todos los estudiantes por igual? Nueve gráficos sobre los datos de PISA
La caída es general, pero no todos han bajado igual: pierden más los alumnos con más recursos, los de centros privados, los extranjeros y comunidades como la Valenciana. Quienes más tiempo pasan en las redes sociales sacan peores notas
All OECD countries have improved their educational results, particularly in reading and mathematics, according to the recently released PISA report. However, Spain has fallen behind the OECD average, but not all students have experienced the same decline. By examining the microdata from the last four editions of PISA, we can highlight some key takeaways from the results.
The averages in the analysis are weighted and calculated based on the ten scores PISA assigns to each student. The "total" score is the average of the three tests, a calculation made by PISA and not a figure provided by the OECD. Some graphs also include the 95% confidence intervals for each average. There are also four caveats to the data: Spain's 2018 reading score was not published by the OECD; gender measurement differs between 2022 and 2025, so following one group between the two years is only indicative; Catalonia is excluded from the autonomous region breakdown due to PISA's concerns; and in the question about social media usage, 21% of the 2025 sample responded, compared to 11% in 2022, so those data points are only available for 2025.
