Ontario School Rankings Explained: What the Numbers Really Mean

Understand how Ontario school rankings work, what EQAO-based scores measure, and how to use rankings wisely when choosing a school for your child.

Updated March 1, 2026

What are school rankings?

School rankings are numerical scores or lists that attempt to order schools from "best" to "worst" based on specific criteria — typically standardized test results. In Ontario, the most commonly cited rankings are derived from EQAO assessment data. Organizations like the Fraser Institute, Right School, and others analyze this data and publish school-level scores. While rankings can be a useful starting point, understanding what they measure (and what they don't) is essential for making informed decisions.

How Right School calculates its scores

Right School analyzes EQAO results across all assessed grade levels and subjects for each school. We calculate the percentage of students meeting the provincial standard in reading, writing, and mathematics at Grades 3, 6, and 9, plus the OSSLT pass rate at Grade 10. These percentages are weighted and combined into a single score out of 10. We also factor in three-year performance trends — schools with improving results receive credit for their trajectory. The result is a composite score that reflects both current performance and momentum.

What rankings can tell you

Rankings are most useful for identifying patterns and narrowing your search. A school with a high score consistently outperforms the provincial average across multiple subjects and grade levels. Rankings also help you spot trends — a school that has been improving for three consecutive years may be a great choice, even if its current score is not the highest. Comparing nearby schools using rankings can quickly surface options you might not have considered.

What rankings cannot tell you

Rankings based on EQAO data do not capture many things that matter to families: school culture and community, extracurricular offerings, quality of arts and sports programs, support for students with special needs, student well-being and mental health resources, or the fit between a school's approach and your child's learning style. A school ranked #1 in your city might not be the right fit for your child. Rankings are a starting point for research, not the final answer.

How to use rankings wisely

Use rankings to create a shortlist, not to make a final decision. Start by filtering schools in your area using Right School. Compare scores and trends for your top choices. Then go deeper — visit the schools, attend open houses, talk to teachers and parents, and consider your child's personality and needs. The best school for your child is the one where they will thrive academically, socially, and emotionally. Data helps you narrow the options; your judgment and knowledge of your child will guide the final choice.

Frequently asked questions

Are school rankings accurate?

Rankings based on EQAO data are as accurate as the underlying assessment data, which is collected by an independent provincial agency. However, they measure a specific set of academic outcomes and do not capture everything that makes a school good or right for a particular child.

Why do different websites show different school rankings?

Different organizations may use different methodologies, weighting systems, data years, or criteria. Right School uses the most recent EQAO data and factors in three-year trends. Other sites may weight subjects differently or include additional variables.

Should I choose a school based only on its ranking?

No. Rankings are a valuable tool for narrowing your options, but the best school for your child depends on many factors beyond test scores — including location, culture, extracurriculars, and your child's individual needs.
