[#PISA]() [#OECD]() [#Education]() #DataAnalysis #Socioeconomic # PISA socioeconomic data accuracy questioned 23 September 2026 at 10:05 > Researchers claim the OECD used incomparable metrics to report a widening performance gap between student socioeconomic groups in PISA. Researchers from Innovamat Research Lab and EsadeEcPol claim the **OECD** altered its methodology for measuring **socioeconomic** levels in the **PISA** report. The study suggests that variables from 2022 and 2025 were compared despite being technically incomparable. The 2025 index removed 11 indicators, including questions about books, adding items like swimming pools and security systems. While the PISA Technical Report warned against comparisons, Volume I compared these statistics against previous cycles regardless. Recalibrated data shows the performance gap in Mathematics between socioeconomic quartiles changed by only 1.6 points, not the 11.2 points reported. Experts confirm the global decline is real but occurred equally across all student socioeconomic groups. ## Related news [#Madrid]() [#Education]() #Scholarships #Baccalaureate #Students 28 October 2026 at 20:18 ## [Madrid awards 17,400 Baccalaureate scholarships]() > The Community of Madrid invests 43.5 million euros in grants for students at private and charter schools for the 2026-2027 academic year.
