Catalonia's education system is facing significant scrutiny following the invalidation of its results in the 2025 Programme for International Student Assessment (PISA). The Organisation for Economic Co-operation and Development (OECD) excluded Catalonia's data from the international report due to a technical issue that compromised the sample's representativeness. This exclusion raises concerns about the accuracy of assessments and the effectiveness of educational policies in the region.
The issue stemmed from the erroneous exemption of approximately 500 students with disabilities from the PISA sample, leading to a 23% exclusion rate. The OECD recommends a maximum exclusion rate of 10%, indicating a significant deviation from standard procedures. Consequently, while Catalonia's data will appear in Spain's national report, it will not be comparable to other regions or previous international assessments.
This incident is the latest in a series of challenges facing Catalonia's education system. Recent reports highlight a persistent decline in academic performance, with students underperforming in reading, mathematics, and science compared to national and OECD averages. The Foundation Equitat's annual education report points to entrenched inequalities and insufficient public policies as contributing factors.
In response to these challenges, the OECD has called for increased investment in education, emphasizing the need to attract better-qualified teachers through improved compensation. The organization also urges the reversal of existing inequalities to enhance educational outcomes.
The Catalan government has acknowledged the severity of the situation. Education Minister Esther Niubó has stated that the administration is committed to transparency and accountability, with ongoing investigations to determine the causes of the PISA sample issue. She emphasized the importance of reinforcing controls to prevent future occurrences.
As the investigation into the PISA sampling error continues, stakeholders await further developments. The outcomes of this inquiry are crucial for shaping future educational policies and restoring confidence in Catalonia's education system.
