Data quality
How this rating is calculated
We import official provincial assessment results (EQAO) and compute a weighted average of the available test metrics for each school. That raw composite is then converted into a 1–10 decile ranking relative to other ON schools with data in the same year.
- Academic rating — the school's weighted composite score, scaled to 0–10.
- Provincial decile — 10 = top 10% of schools, 1 = bottom 10%.
- Data quality — reflects how many subjects/grades contribute. "Complete" = several assessments; "Partial" = a few; "Limited" = very few.
Missing data does not lower a school's rating. We only display a rating when assessment data is available.
