Ontario Grade 9 Math and the EQAO Test: What Parents Need to Know (2026-27)

From the 2026-27 school year, the EQAO Grade 9 math assessment counts as the course's written exam and makes up 20% of a student's final Grade 9 math mark. For many Ontario families, that turns a provincial test into something that shows up directly on the report card and transcript.

Here's what the course covers, how the test works, what changed this year, and where students usually lose marks.

The Grade 9 math course (MTH1W)

Since 2021, Ontario has taught Grade 9 math as a single de-streamed course, MTH1W, rather than separate academic and applied courses. Every student takes the same course, based on the 2021 Grade 9 mathematics curriculum, which includes coding and financial literacy alongside number, algebra, data, and geometry and measurement.

It's also the foundation for everything after it: the Grade 10 course your child chooses next, and senior courses such as Advanced Functions and Calculus and Vectors, which many university programs require.

How the EQAO Grade 9 math test works

• When: at the end of the Grade 9 math course.
• Format: online and adaptive. The test adjusts to how a student is doing as they go.
• Length: two sessions, each designed to take about 60 minutes and completed in one sitting. The sessions can be on the same day or different days.
• Questions: 54 in total, of which 50 are scored. The other four are field-test questions that don't count.
• Results: an overall level from 1 to 4, with level 3 as the provincial standard.

What changed for 2026-27

• EQAO is now the Grade 9 math exam. The EQAO assessment counts as the written exam for MTH1W and makes up 20% of the final mark. Under the 2025-26 rules, schools could weight it anywhere from 10% to 30%.
• A new mark structure. In Grades 9 and 10, final marks are now 65% classroom work, 20% final evaluation and 15% attendance and participation. In Grades 11 and 12 it's 65%, 25% and 10%. In math, English and science the final evaluation is a written exam.

In practice, a fifth of the Grade 9 math mark now rides on a single assessment at the end of the course, and senior math courses carry a 25% final exam.

The pressure is real: in EQAO's 2024-25 results, 58% of Grade 9 students in English-language schools met the provincial standard in math, so roughly four in ten did not.

Where students usually lose marks

Algebra foundations

Algebra is more than a third of the test. Students who struggle with it are often missing something from Grades 7 and 8: working with negative numbers, fractions in equations, or understanding what a variable represents. Re-teaching Grade 9 algebra won't fix a Grade 7 gap.

Proportional reasoning

Rates, ratios and percentages appear across number, algebra and financial literacy questions. Weak proportional reasoning costs marks in several strands at once.

Multi-step problems

Many questions require choosing a method rather than applying one that has been signposted. Students who can follow a worked example but can't start an unfamiliar problem tend to underperform here.

Financial literacy

It's a newer part of the curriculum and worth 12% of the scored questions. Topics such as interest, budgeting and comparing financial options reward practice with real-life contexts.

How to help

1. Ask the teacher early. Find out your child's current mark, which strands are weakest, and when the course and the EQAO assessment end.
2. Try the sample test. EQAO publishes a sample test so students can practise with the online platform and its tools.
3. Use free tutoring. TVO Learn Mathify gives Ontario students in Grades 4-12 free one-to-one online help from Ontario Certified Teachers, using their Ontario Education Number to sign up.
4. Check Grade 7-8 skills. If algebra is the problem, look one or two years back: integers, fractions and solving simple equations.

When one-to-one tutoring makes sense

If your child's Grade 9 math mark is sliding, or they're well below level 3 in class, regular one-to-one help aimed at the underlying gap is worth considering, especially now that the end-of-course assessments carry more weight.

TaleemSquare teaches one-to-one math online aligned to the Ontario curriculum, scheduled in Eastern time, from C$115 a month for two 45-minute lessons a week. Every student starts with a free assessment that checks the Grade 7-8 skills Grade 9 builds on. For a comparison of options, see our Canadian math tutor price guide.
