How to read these numbers
What this data can and can’t tell you
- Boards and systems. Public and Catholic boards are both publicly funded here, in English and in French; an independent school answers to no board.
- The year. Listed for 2024-25.
- Bands, not ranks. A band is the fifth of Ontario’s schools a result falls in, averaged over the school’s measures; small groups go unreported, so places would overstate it.
- What isn’t here. No ratings by inspectors, no enrolment trend: neither is published school by school.
- The kinds of school. Elementary and secondary come from the grades each school offers; a school offering both counts as all-grade.
- Which schools count. Each school is placed by its address point; those inside Thornlea or within 3 km of it are here.
