The Ontario curriculum is the Ministry of Education's official list of what students in publicly funded Ontario schools are expected to learn in each subject, from Kindergarten to Grade 12. TutorLyft tutors use these same expectations to match their sessions to what students are learning in class.
If a report card comment, a course code like MPM2D or a new style of math homework has left you puzzled, the curriculum is usually the key to making sense of it. Below, we'll walk through how it's organised, how marks and achievement levels work, what de-streaming and the OSSD mean, and where to find the documents yourself.
What the Ontario curriculum is
The Ontario curriculum is the set of learning expectations written by the Ontario Ministry of Education. Every publicly funded school in Ontario follows it, from Kindergarten to Grade 12. TutorLyft tutors use the same expectations to connect their sessions with what students are learning in class.
It helps to think of the curriculum as a list of goals, not a lesson plan. It spells out what a student is expected to know and be able to do by the end of each grade or course. How a class reaches those goals, including the books, projects and order of units, is up to the teacher.
The curriculum is also free and public. You can read the exact documents your child's teacher plans from whenever you like, without signing up for anything.
Who creates and updates the Ontario curriculum
A few different groups have a hand in the Ontario curriculum, and each one has its own job:
- Ontario Ministry of Education: writes, publishes and revises every curriculum document.
- School boards: put the curriculum into practice and set local rules, such as exam schedules or homework guidelines.
- Teachers: plan lessons and choose resources that match the expectations.
- Parents and students: can read the same documents teachers use, at no cost.
So why does your younger child's math homework look so different from what your older child brought home at the same age? Usually, it's because the Ministry updates one subject at a time rather than all at once. A subject can change between one sibling and the next.
More updates are already scheduled. According to the Ministry's list of upcoming curriculum revisions, a new Kindergarten program and updated Grades 7 and 8 History expectations are planned for the 2026–27 school year.
What subjects the Ontario curriculum covers
The subjects shift a little as students move through school. Here's a quick map of the main areas at each stage in Ontario:
One small note: French-language schools in Ontario follow their own parallel set of curriculum documents. The Ministry publishes them in French, and they cover the same broad subject areas.
How the Ontario curriculum is organised
Every subject is divided into strands, which are the big topic areas within that subject. In Ontario's Grades 1 to 8 math curriculum, for example, the strands include Number, Algebra, Data, Spatial Sense and Financial Literacy.
Next, each strand has two layers of expectations:
- Overall expectations: the broad goals a student is expected to reach by the end of the grade.
- Specific expectations: the smaller, detailed skills that build toward each broad goal.
Let's look at Grade 5 math. The Number strand has an overall expectation about knowing how numbers work and how people use them in everyday life. Underneath it sit specific expectations for skills such as comparing and ordering fractions.
You'll also notice short codes beside each expectation. An overall expectation might be labelled B1, while the specific expectations under it are B1.1, B1.2 and so on. Teachers sometimes use the codes when planning or writing feedback, so spotting them can make a comment much easier to follow.
How Ontario students are assessed and evaluated
Ontario's assessment rules come from Growing Success, a Ministry of Education policy document published in 2010. It asks teachers to look at four kinds of learning, known as the achievement chart categories:
- Knowledge and Understanding: what the student knows and remembers.
- Thinking: how the student plans, reasons and solves problems.
- Communication: how clearly the student shares ideas in writing, speech or visuals.
- Application: how well the student uses what they know in new situations.
Then, student work is placed on one of four achievement levels. Level 3 is the provincial standard, which simply means the student has met the expectations for the grade. Here's how Growing Success matches each level to marks:
So, is 80% an A in Ontario? Yes. It sits right at the start of Level 4.
Teachers also collect evidence in three ways: talking with students, watching them work, and marking what they hand in, such as tests and projects. This approach is called triangulation, which is a fancy word for looking at learning from more than one angle.
In high school, final marks are split between classroom work and end-of-course evaluations. According to an Ontario Newsroom release on student achievement, classroom work accounts for 65 per cent of final marks, while final evaluations count for 20 per cent in Grades 9 and 10 and 25 per cent in Grades 11 and 12.
Elementary expectations by grade band
Elementary school in Ontario moves through three broad stages. Each one builds on the last, so here's a quick look at what usually happens along the way.
Grades 1 to 3 and early foundations
In the early grades, reading, writing and number sense come first, since early literacy lays the groundwork for nearly everything that follows. Ontario's revised Language curriculum puts a strong focus on phonics, which is the link between letters and the sounds they make. Learning at this age is very hands-on: counting blocks, sounding out words and making simple science observations.
Grades 4 to 6 and growing independence
Around Grade 4, students shift from learning to read toward reading to learn. In math, they spend more time on fractions, decimals, geometry and data. Writing becomes more structured, and teachers ask students to explain their thinking more often, not just give an answer.
Grades 7 and 8 and the move to high school
By Grades 7 and 8, Social Studies splits into two separate subjects, History and Geography, and the work becomes more abstract. Grade 8 math leads straight into MTH1W, the Grade 9 math course every Ontario student takes. Report cards change too, switching from letter grades to percentage marks.
Secondary course codes and the OSSD
High school in Ontario runs from Grade 9 to Grade 12 and leads to the Ontario Secondary School Diploma (OSSD). According to Ontario's high school graduation requirements, students earn 30 credits (18 compulsory and 12 optional), complete 40 hours of community involvement, and meet a literacy requirement. A credit is earned by passing a course, usually one that lasts a semester.
Every Ontario high school course also has a five-character code. At first, the codes can look like a secret language. Once you know the pattern, though, a course selection sheet becomes much easier to read:
The final letter is often the one families ask about most. Here's what each letter usually means:
- W: de-streamed Grade 9 course, taken by all students
- D: Academic, with more focus on theory and abstract thinking
- P: Applied, with more focus on practical, hands-on learning
- U, C, M or E: University, College, University/College, or Workplace preparation in Grades 11 and 12
- O: Open, suitable for all students
De-streaming in Grade 9 and what it means for students
Ontario used to be the only province streaming Grade 9 students, asking them to pick between Academic and Applied versions of their core courses. Many families found the choice stressful, especially for a 14-year-old. De-streaming changed the system, so all Grade 9 students now take the same course together in the same classroom.
The change happened in steps:
- Math first: MTH1W, the de-streamed Grade 9 math course, began in September 2021.
- Other subjects next: more Grade 9 courses followed, including ENL1W (English) and SNC1W (Science).
However, choices don't disappear entirely. From Grade 10 onward, course types return in many subjects. Later, Grade 11 and 12 choices shape which university and college programs a student can apply to, since programs list specific courses as prerequisites.
Before Grade 10 course selection, look up the prerequisites for any university or college programs your teen is curious about. A guidance counsellor can help map out the path, one year at a time.
EQAO assessments and what they measure
The Education Quality and Accountability Office (EQAO) is an independent provincial agency that runs Ontario's standardized tests. A standardized test is written by every student in the same grade, under the same conditions, so results can be compared fairly across the province. In Ontario, students write EQAO tests at four points:
- Grade 3: reading, writing and math
- Grade 6: reading, writing and math
- Grade 9: math, based on MTH1W
- Grade 10: the Ontario Secondary School Literacy Test (OSSLT)
Of the four, the OSSLT is the one with real stakes for a student. Passing it, or completing the Ontario Secondary School Literacy Course (OLC4O) instead, is part of the OSSD literacy requirement, and in 2024–25, 50% of previously eligible students who wrote the OSSLT were successful. The Grade 3 and Grade 6 results, on the other hand, don't decide whether a child moves on to the next grade. Still, according to EQAO data reported by CBC News, 52% of Grade 6 students met the provincial math standard in 2025–26.
Recent updates to the Ontario curriculum
If homework suddenly looks unfamiliar, a recent revision is often the reason. Two updates have changed Ontario elementary classrooms the most.
Mathematics curriculum update
Ontario's revised Grades 1 to 8 math curriculum arrived in 2020. It added Financial Literacy as its own strand, so students now learn about money, budgeting and saving at every grade. It also brought coding into the Algebra strand and added social-emotional learning skills, such as staying calm and trying again when a problem feels hard.
Language curriculum update
Next came the revised Grades 1 to 8 Language curriculum, which took effect in September 2023. It places much more weight on direct phonics teaching, vocabulary and the science of reading, an approach based on research about how children learn to read. Parents of younger children may notice more sound and spelling practice coming home.
How to find and read Ontario curriculum documents
Every current document lives on the Ministry of Education's Curriculum and Resources website. You can search by subject and grade, and everything is free to view or download.
Some of the documents run quite long, but you don't have to read them cover to cover. A few habits make them far more manageable:
- Start with your child's grade: jump straight to the right grade and subject instead of reading from the beginning.
- Read the overall expectations first: they give the clearest picture of the year ahead.
- Check the glossary: most documents explain subject words near the end.
- Compare with report cards: teacher comments often borrow wording straight from the curriculum.
How curriculum-aligned tutoring supports Ontario students
Tutoring tends to work best when it lines up with what a student is learning in class right now. A tutor who knows the Ontario curriculum can often spot the exact strand or expectation causing trouble and spend the session there. On TutorLyft, families can compare vetted tutors, look for the qualities of a good tutor and choose one with experience in Ontario courses, whether the subject is Grade 6 fractions or SBI3U, the Grade 11 university preparation biology course.
Supporting your child at home with Ontario curriculum expectations
You don't have to be a teacher to put the curriculum to good use at home. A few small habits can make a real difference:
- Ask about strands: instead of "How's math going?", try "What are you working on in Data right now?"
- Use expectations as talking points: the overall expectations give you clear, specific topics to chat about.
- Link homework to goals: if an assignment seems confusing, the matching expectation often shows what skill it's trying to build.
Even a basic sense of how the documents are set up can make conversations with your child's teacher more focused and a lot less stressful.
Getting help when the curriculum feels overwhelming
Even with a clear map, some students hit a wall. Maybe a concept just won't click, or the jump from one grade to the next feels steeper than expected. That's normal, and it doesn't mean your child is permanently behind. Taking the time to find where the gap is, rather than rushing to fill it, usually leads to steadier progress.
