What this data can and can’t tell you
- 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. A school counts when it sits inside St. Marys or less than 3 km beyond its edge.
- Boards and systems. English and French, public and Catholic: the board decides the system, and the address decides the school.
- The year. The 2024-25 list.
- Bands, not ranks. The fifths are of schools, not students: a small school counts as much as a large one.
- What isn’t here. Enrolment is a single year, where published at all, and no inspectorate rates schools.
