How does St Mary's High School compare to other Kitchener secondary schools?
On the 2024–2025 EQAO assessments, 71% of St Mary's High School students met the provincial standard (composite) — higher than 3 of the 8 other Kitchener secondary schools with published results.

How should I read the EQAO results for St Mary's High School?
EQAO results show the percentage of students who met or exceeded the provincial standard on each assessment, shown alongside the Kitchener secondary average for context. They are provided for information only and are not a ranking of school quality — academic outcomes are just one of many factors families may wish to consider.

Open the Compare tool to line up St Mary's High School against up to three other schools — EQAO results, grades, board and catchment status side by side.
Does living in St Mary's High School's catchment guarantee a spot?
Not automatically. Falling inside the attendance boundary is the basis for enrolment, but it is not an absolute guarantee — placement still depends on school capacity, program availability such as French Immersion, and board policy. Always confirm current school boundaries and registration directly with Waterloo CDSB.

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EQAO results, programs and enrolment — is provided for general informational purposes only and may be inaccurate or out of date.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.
