How we rank schools
1. Official results only
Every number comes from the Ontario Ministry of Education's school information file for 2024–25 (extract September 14, 2026). It reports the percentage of students who met the provincial standard on each EQAO test. Nothing is estimated or made up.
2. One simple average
Elementary: the average of the school's published Grade 3 and Grade 6 reading, writing and math results (at least three needed). Secondary: the average of Grade 9 math and the Grade 10 literacy test (OSSLT) first-time pass rate.
3. Ranked within each city
Schools are ordered by that average, separately for elementary and secondary. Schools with no published results (often too few students) and alternative, online or adult schools are listed but not ranked.
These are not Fraser Institute ratings. The Fraser Institute publishes its own 0–10 report cards at compareschoolrankings.org. EQAO results are one measure of a school, so visit the school and talk to the board before deciding.
