Students across Ontario write province-wide assessments of their reading, writing and math skills at key stages in their elementary and secondary school education:
| Grade 3 | Literacy and math tested at the end of the primary division |
| Grade 6 | Literacy and math tested at the end of the junior division |
| Grade 9 | Math tested in the first year of secondary school |
| Grade 10 | Literacy tested as a graduation requirement |
The tests are administered by the Education Quality and Accountability Office (EQAO), an arm’s-length agency of the Ministry of Education.
EQAO distributes an individual report to each student who writes the tests and posts school, school board and provincial results on its Web site. Schools and school boards also create their own reports of EQAO data for distribution to parents and others in their communities.
