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.

How should I read the EQAO results for Middlefield Collegiate Institute?
EQAO results show the percentage of students who met or exceeded the provincial standard on each assessment, shown alongside the Markham secondary average for context.

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 York Region DSB.

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EQAO results, programs and enrolment — is provided for general informational purposes only and may be inaccurate or out of date.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