Understand PISA.
Not just the ranking.
PISA 2025 scores, country results, subject performance and the patterns behind the numbers — with full datasets, searchable tables and statistical context.
One release. Four ways in.
Country rankings, subject scores and the full international results each answer a different part of the same assessment cycle.
The headline is not one ranking.
PISA 2025 looks different depending on whether the question is current level, recent change, distribution or statistical uncertainty.
Science was steadier than reading and mathematics.
On the comparable OECD set, science moved by about 3 points from 2022, compared with declines of 9 points in mathematics and 14 in reading.
Adjacent positions are not always statistically different.
Reported means are estimates. Small score gaps can produce different displayed positions without establishing a clear performance difference.
A mean score never tells the whole student story.
Systems with similar averages can still differ in low-performer shares, top-performer shares and the spread between students.
Data first.
Analysis second.
EduScores keeps international assessment data inspectable without turning estimates into simplistic league tables.
Full data stays visible. Search and sorting enhance the table; they never replace the source rows.
Rank is treated carefully. Score-based ordering is separated from statistical significance.
Analysis earns its place. Charts and notes must reveal a pattern, change or contrast — not repeat the table.
Official sources lead. OECD reports, databases, dashboards and technical documentation anchor the data.
The full international picture.
Country and economy results across science, mathematics and reading in one dataset.
