View all EQAO results (2024–2025)
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, and at a school this size a single grade is a few dozen students, so a few points can reflect who wrote it rather than a change at the school. EQAO does not report a result where fewer than 10 students wrote.
Six years of results
Every year the Ministry of Education has published for St Mark Catholic Elementary School, oldest first. Each year is a different group of students.

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.
