EQAO Grade 9 Math: The Complete 2026 Prep Guide (Ontario)
What is the EQAO Grade 9 math assessment?
The EQAO Grade 9 Assessment of Mathematics is a standardized test written by Ontario students taking the Grade 9 math course. It is run by the Education Quality and Accountability Office (EQAO), an agency of the Government of Ontario, and it measures how well students have learned the expectations of the de-streamed Grade 9 math course (course code MTH1W), introduced in 2021.
It is now a digital, computer-based assessment. Students complete it on screen at school, usually near the end of the course, with a built-in calculator and formula sheet available throughout.
How is the EQAO Grade 9 math test structured?
The assessment has about 50 questions split across two sessions of roughly 60 minutes each. Most questions are multiple-choice, with some open-response and technology-enhanced questions (such as drag-and-drop). Here's the quick breakdown:
| Detail | What to expect |
|---|---|
| Delivery | Computer-based, on screen at school |
| Length | ~50 questions across two ~60-minute sessions |
| Question types | Mostly multiple-choice, plus open-response and technology-enhanced items |
| Tools provided | On-screen calculator and formula sheet (physical calculator also allowed) |
| Course covered | De-streamed Grade 9 mathematics (MTH1W) |
| Weight | Up to 30% of the final course mark (board's discretion) |
How much does EQAO count toward your final grade?
The Grade 9 math assessment can count for up to 30% of your final mark in the course. Crucially, each school or school board decides whether to count it and for how much — some count the full 30%, some less, some not at all. Ask your math teacher for your school's exact policy so you know what's at stake.
What topics are on the EQAO Grade 9 math assessment?
The test covers the strands of the MTH1W curriculum. Focus your studying on these areas:
- Number — fractions, decimals, percentages, integers, powers, and ratios/rates.
- Algebra — algebraic expressions, solving linear equations, and an introduction to coding.
- Data — collecting, representing, and analyzing data; reading graphs.
- Geometry and Measurement — area, perimeter, volume, and the Pythagorean theorem.
- Financial Literacy — budgets, simple and compound interest, and comparing financial choices.
- Linear relations — graphing lines, slope, and connecting equations to graphs (a heavily tested area).
How to study for EQAO Grade 9 math: a 5-step plan
- Take a diagnostic. Do one full-length practice assessment first. The goal isn't the score — it's finding which strands are weakest so you don't waste time on what you already know.
- Rebuild the fundamentals. Most Grade 9 mistakes trace back to fractions, integers (negative numbers), and solving linear equations. Lock these down before moving on.
- Work strand by strand. Spend focused sessions on one strand at a time. Master linear relations and algebra especially — they carry a lot of weight.
- Practise on screen. Because the test is digital, practise using an on-screen calculator and formula sheet so the format is familiar, not a distraction, on test day.
- Simulate the real thing. In the final week, do timed, full-length simulations to build pacing and stamina for two back-to-back sessions.
Common mistakes to avoid
- Cramming new topics the night before. Review and pacing beat new learning at that point — sleep matters more than one more topic.
- Skipping the formula sheet. Know what's on it so you're not memorizing formulas you'll be given.
- Ignoring units and rounding. Measurement and financial-literacy questions punish careless units and rounding.
- Not reading multiple-choice options fully. The "almost right" distractor is there on purpose.

Frequently asked questions
How much does the EQAO Grade 9 math assessment count toward my grade?
It can count for up to 30% of your final mark in the Grade 9 math course. Each school or school board decides whether to count it and for how much, so ask your teacher for your school's policy.
What format is the EQAO Grade 9 math assessment?
It is a computer-based assessment of the de-streamed Grade 9 math course (MTH1W). It has about 50 questions across two roughly 60-minute sessions, mostly multiple-choice with some open-response and technology-enhanced questions, plus an on-screen calculator and formula sheet.
Can you use a calculator on the EQAO Grade 9 math test?
Yes. An on-screen calculator and a formula sheet are built into the assessment, and you may also use a physical calculator. Practising with these tools beforehand makes the real test feel familiar.
How do I study for EQAO Grade 9 math?
Take a diagnostic to find weak strands, rebuild fundamentals (fractions, integers, linear equations), then practise strand by strand: Number, Algebra, Data, Geometry and Measurement, and Financial Literacy. Finish with timed, full-length simulations.
