When is EQAO 2026 Grade 9? The Grade 9 EQAO mathematics assessment is written in two windows each school year: a winter window in January 2026 for students who take MTH1W in Semester 1, and a spring window in June 2026 for students in Semester 2 or full-year courses. Your child’s school chooses the exact day within the relevant window, so the precise date depends on which semester your child takes Grade 9 math. This guide gives you the full date picture, explains how the windows work, and shows you how to use the time before the assessment with grade 9 EQAO practice and the official EQAO sample test grade 9 so your child walks in confident.
When is EQAO 2026 Grade 9? (Quick answer)
The Grade 9 EQAO is written during two testing windows in the 2025/2026 school year, and which one your child writes in depends on when they take the MTH1W course.
| Semester | MTH1W course runs | EQAO window | Approximate dates |
|---|---|---|---|
| Semester 1 | September – January | Winter window | January 2026 |
| Semester 2 | February – June | Spring window | June 2026 |
| Full-year | September – June | Spring window | June 2026 |
The single most important thing to know: schools choose the specific date within the window, so two students in different schools — or even different classes — might write on different days. Your child’s math teacher will confirm the exact date a few weeks beforehand.
How the EQAO Grade 9 testing windows work
Unlike the Grade 3 and Grade 6 EQAO assessments — which are written once a year in late spring — the Grade 9 EQAO runs twice a year because the MTH1W course is offered in both semesters.
Why there are two windows
Grade 9 math (MTH1W) is a semester-long course in most Ontario high schools. Students who take it in the first semester finish in January, so they write the EQAO in the January window. Students who take it in the second semester finish in June and write in the June window. Schools running full-year math write in June.
This is different from elementary EQAO, where every student is in the same grade-long curriculum and writes at the same time of year.
How schools choose the exact date
EQAO publishes a multi-week window for each session. Within that window, each school chooses specific days that fit its timetable, computer lab availability, and exam schedule. This is why there’s no single province-wide “EQAO Grade 9 day.”
The assessment is usually written close to the end of the course — in the last few weeks of the semester — so the material is fresh and students have covered the full curriculum.
How to find your child’s exact date
Three ways:
- Ask your child’s math teacher. They’ll know the school’s chosen date, usually confirmed a few weeks ahead.
- Check school communications. Many schools send a note home or post the date on their website or parent portal.
- Check the EQAO website for the official window, then narrow it down with the school.
Key EQAO 2026 Grade 9 dates and deadlines
Beyond the test day itself, a few other dates matter.
| Milestone | Semester 1 (winter) | Semester 2 / full-year (spring) |
|---|---|---|
| MTH1W course ends | January 2026 | June 2026 |
| EQAO testing window | January 2026 | June 2026 |
| Specific date confirmed by school | A few weeks before | A few weeks before |
| Results released | Spring/summer 2026 | Fall 2026 |
How long is the assessment?
The Grade 9 EQAO takes approximately two hours total, usually split across two sittings, written on a computer at school during regular class time. It’s not a single long exam — your child writes it in their normal math periods over one or two days.
What is the EQAO Grade 9 assessment?
If you’re new to the Grade 9 EQAO, here’s the short version.
The Grade 9 EQAO is Ontario’s province-wide mathematics assessment, written by every Grade 9 student during their MTH1W course. It’s run by the Education Quality and Accountability Office (EQAO) and tests whether students have met the Grade 9 math curriculum expectations.
Crucially, the Grade 9 EQAO counts toward your child’s mark — in most Ontario school boards, it’s worth 10% of the final MTH1W grade. This makes it the only EQAO assessment with a direct report card impact, and it’s why preparation matters more at Grade 9 than at the elementary levels.

How to prepare before the EQAO 2026 Grade 9 date
Once you know your child’s testing window, you can work backwards to plan preparation. The ideal runway is about eight weeks, but even a few focused weeks make a difference.
8 weeks out — diagnose
Sit the official EQAO sample test (see below) under timed conditions. Mark it and identify the two weakest strands. For most Grade 9 students, the weak spots are financial literacy (new to the curriculum) and geometry/measurement (especially surface area and volume).
6–3 weeks out — target the gaps
Spend 20 minutes a day on the weakest strands. The highest-leverage Grade 9 topics are:
- Linear relationships and slope — the most-tested topic on the assessment. See our point slope formula guide.
- Surface area and volume of 3D solids — especially cylinders. See our cylinder guide.
- Integer operations — the foundation for all the algebra. See our adding and subtracting integers guide.
- Financial literacy — simple and compound interest.
2 weeks out — full practice tests
Do one or two full timed practice tests on the EQAO computer platform, with detailed review of every mistake afterward. For the complete grade 9 EQAO practice strategy, see our EQAO Grade 9 practice test guide.
The final week — rest, don’t cram
Make sure your child is sleeping well and feeling calm. Don’t introduce new material. The work is done — the last week is about arriving rested and confident.
