Ontario Just Changed How Your Child's Final Grade Is Calculated: Here's What's Different This Year

Your child's report card is about to look different. Not just the grades themselves, but how those grades are actually calculated. And if you're an Ontario parent, you probably haven't heard about it yet.

Starting this September, Ontario's Bill 101 (the Putting Student Achievement First Act) has completely reshuffled the way final grades work for Grades 9–12. The old formula you might remember from your own school days? It's gone. And the first report card of the year is going to reflect it.

The Old System vs. The New System

For decades, Ontario used a pretty straightforward split: 70% coursework, 30% final evaluation. That was it. You did your assignments and tests throughout the year, and then one big exam at the end determined a third of your grade.

Not anymore.

Here's the new breakdown:

Grades 9 & 10:

• 65% coursework

• 20% final evaluation (written exam)

• 15% attendance and participation

Grades 11 & 12:

• 65% coursework

• 25% final evaluation (written exam)

• 10% attendance and participation

And here's the kicker: written exams are now mandatory in English, math, and science.

Why This Matters (And Why You Should Care Now)

If you're thinking, "Okay, my kid does fine on tests, so this shouldn't be a big deal," hold on. This change affects three major components of your child's grade, and each one requires a different strategy.

The Exam Piece

For Grades 11 & 12, that final exam now counts for 25% of the entire grade. That's a quarter of their mark resting on one assessment. If your child is someone who gets nervous during timed tests, or who tends to overthink multiple-choice questions, or who freezes when they see a blank page, this is the month to start building their test-taking stamina. Not December. Not when they're cramming the night before. Now.

The same goes for Grades 9 & 10, where the exam is worth 20%. Still significant.

The Attendance and Participation Piece

Here's something a lot of families don't realize: "participation" isn't just about raising your hand in class. It's a formal percentage of your grade now. And attendance is tied directly to that mark.

If your child misses more than 9 classes without an excuse, their participation mark drops below 50%. That's a real hit to their final grade: potentially the difference between a B and a B-.

We're talking about absences that add up over a few months. A couple of sick days here, a family trip there, and suddenly you're in dangerous territory.

The Coursework Piece

The good news? Coursework still counts for 65% (or 65% in both grade bands). This is where consistent effort pays off. But here's the thing: if your child is banking on doing really well on the final exam to boost a shaky coursework average, they're going to be disappointed. The exam can only do so much.

Working through the exam format, attendance tracking, and coursework changes on your own is doable, but it takes real time to stay on top of every course your child is taking.

Three Things You Should Do This Month

1. Talk to your child's teachers about the exam format.

Don't wait until October or November. Ask specifically:

• What format is the exam (multiple choice, short answer, essay, a mix)?

• When is it scheduled?

• What materials are allowed (calculator, notes, dictionary)?

• How much of the exam is cumulative vs. just the current unit?

This information helps your child prepare strategically. It also shows teachers that families are engaged and taking the new system seriously.

2. If your child struggles with timed written tests, start practicing now.

This is the time to build confidence. Practice timed writing. Practice reading test questions carefully. Practice managing anxiety during assessments. A tutor or teacher can help, but so can consistent, low-pressure practice at home.

3. Track attendance proactively.

Know how many classes your child has missed so far (excused and unexcused). Set a family expectation about attendance. If your child is on the fence about going to school because of a minor cold or social anxiety, this is the month to have that conversation. Nine absences might sound like a lot, but it goes faster than you'd think.

What Your Child Should Know

If you're a student reading this: your teachers aren't trying to make life harder. They're trying to make sure that by the time you graduate, you can actually do something with what you've learned, not just regurgitate it on a test. The new system is designed to reward consistent effort and preparation, not just test-day luck.

That said, if you know you're not great at exams, or if you hate showing up to class, or if you're falling behind in coursework, say something now. Talk to your parents. Talk to your teacher. Talk to a tutor. September is the time to get support in place, not June when you're panicking about your final mark.

The Bottom Line

Ontario's grading system just got more transparent and more demanding. The good news? You now have a clear picture of exactly what goes into your child's grade. The better news? You have time to adjust and prepare.

Save this breakdown. Share it with your child. And if you're noticing that your student is struggling with any of these three components (exams, attendance, or coursework), don't wait until November to get help.

If your student is struggling with exam anxiety, falling behind in coursework, or needs help building a study plan for the new system, book a consultation with us. Our tutors specialize in helping Ontario students master not just the material, but the strategies they need to succeed under the new grading framework.
