Three-year change is published by the Ministry of Education: the difference in percentage points between the 2024–2025 and 2022–2023 assessments. Each assessment is written by a different group of students. EQAO does not report a result where fewer than 10 students wrote.

Results are the percentage of students who met or exceeded the provincial standard, as published by the Ministry of Education. A dash means no result was published for that year: EQAO does not report a result where fewer than 10 students wrote. No provincial assessment ran in 2019-20 or 2020-21, so those years are blank for every school and are never joined across. Before 2021–22 the Ministry published separate Academic and Applied Grade 9 results, which are not comparable with the single assessment published since.

School & assessment data

EQAO results are provided for informational purposes only and should not be interpreted as a ranking of school quality. Academic outcomes are only one factor families may wish to consider. EQAO results shown reflect the 2024–2025 assessment.

School and assessment data is sourced from the Ontario Ministry of Education, the Education Quality and Accountability Office (EQAO), Ontario Open Data, and the applicable public and Catholic district school boards across the regions we cover (Southern Ontario).

School information — including school boundaries, eligibility, EQAO results, programs and enrolment — is provided for general informational purposes only and may be inaccurate or out of date. Boundaries, eligibility, programs and enrolment can change at any time. EQAO figures reflect past assessment results, are shown per test relative to the city-wide average, are not a ranking, and do not predict any student's outcome. Always confirm current school boundaries and eligibility directly with the applicable school board before relying on this information.
