Understanding School Ratings
School ratings in this guide are drawn from standardized assessment data and reflect academic performance on a 10-point scale. Ratings above 9.0 represent exceptional performers, 8.0–8.9 indicates strong schools, and 7.0–7.9 reflects solid, above-average institutions.
Schools span public, Catholic, French-language, arts, and independent streams. Use these ratings as one key factor alongside proximity, program specialization, and community fit when evaluating neighbourhoods for your family.
Rating Scale
  • 9.5 – 10.0 — Elite tier
  • 9.0 – 9.4 — Exceptional
  • 8.0 – 8.9 — Strong performer
  • 7.0 – 7.9 — Above average
