Introduction
Finishing high school in Ontario might look hard at first, but the main thing you need to know is about credits. Credits are what you use to finish your fifth year of secondary education. These credits also help you reach your future plans in school and work. If you are a student who wants to choose courses, a parent helping your child, or someone new to Ontario schools, this guide helps you learn about high school credits. It shows you how to get, improve, and handle your credits so you can reach graduation.
Understanding Ontario Academic Credits
“Ontario academic credits” can mean two things. It can be the credits you get now, or an old system that was used before in Ontario, specifically before the formal elimination of the Ontario Academic Credit. A credit is when you finish a high school course that the ministry of education approves. You get recognition for that work.
If you know about the history of high school credits, it will help you see why the system is the way it is today. There was even a year called Ontario Academic Credit year, or OAC, which was part of the changes announced by Premier Mike Harris. By knowing its story, you understand the changes that led to the system high school uses now. Let’s look at what academic credit means for you and see how high school credits changed over time.
What Are Ontario Academic Credits and Their Purpose
In the Ontario education system, an academic credit is given to a student who finishes a 110-hour course. Think of it as one of the building blocks of your high school years of high school. Every credit helps you get closer to earning your Ontario Secondary School Diploma. The school uses them to keep track of your progress toward that diploma.
The Ministry of Education in the province of Ontario checks and controls these high school credits. This helps keep the quality and what you learn the same at every school. It doesn’t matter if you are at a public, Catholic, or private school. Because of this, if you earn a credit at one school, it counts at another without any issue.
In the end, high school credits in Ontario are for more than just your diploma. They show the skills and knowledge you pick up along the way. The credits you choose also affect which college or university programs you can apply to later, so they play a big role when planning your next steps after school, especially as a result of the double cohort.
Changes from OAC Ontario Grade 13 to Today’s System
For many years, the high school system in Ontario had five years of secondary education. The fifth year was called Grade 13 or the Ontario Academic Credit (OAC) year. This extra year of secondary education was for students who wanted to go to university. It had special courses you needed for university admission.
But later, the education system changed. The OAC year was taken away, and the last students in it graduated in 2003. This move made Ontario’s four-year high school model match the rest of North America. When this happened, it created something called the “double cohort.” That’s when students from the five-year system, including those who decided to take an extra year of high school, and four-year systems finished at the same time.
Now, the advanced lessons from old OAC courses are part of the Grade 11 and 12 curriculum. Instead of doing a fifth year, students finish and get their OSSD in four years. They do this by earning 30 academic credits, which prepares them for college, the university of their choice, or to go right into work.
Diploma Requirements in Ontario High Schools
Getting an Ontario Secondary School Diploma (OSSD) is a big step in your life. The diploma requirements are meant to help you have a good education, facilitating the completion of schooling so you are ready for what comes next. The secondary school system in Ontario works with credits that you must earn as a student.
To finish and get your secondary school honours graduation diploma, you need to earn a set number of required and extra credits. You also have to pass a literacy test and do community involvement hours. The credit system gives you a strong start in important classes and lets you try out your own interests too.
Mandatory Credits and Elective Choices for Graduation
The path to graduation requires earning 30 credits in total. Of these, 18 are mandatory credits, ensuring you have essential skills in key subject areas. These compulsory courses cover subjects that are fundamental to your learning and future success. The remaining 12 are elective credits, which you can choose based on your interests and career goals.
These elective choices allow you to explore subjects like technology, the arts, or business, and they can also be used to take the necessary prerequisite courses for specific university or college programs, including those that may have been established following the last OAC. This blend of mandatory and elective OSSD credits gives you a balanced high school education.
Here are some of the mandatory credits you need:
| Mandatory Credits | Number of Credits |
|---|---|
| English | 4 (1 per grade) |
| Mathematics | 3 |
| Science | 2 |
| Canadian History | 1 |
| Canadian Geography | 1 |
| The Arts | 1 |
| Health & Phys. Ed. | 1 |
| French as a Second Language | 1 |
| Civics and Career Studies | 1 (0.5 credit each) |
How OAC Ontario Shaped University Admissions
In the past, the OAC Ontario system had a big role in getting into university. Students had to finish their final year of high school and take OAC courses. Universities would look at grades from your top six OAC level courses. They would use these grades to make an average. This average was the main thing they used to decide if you got in.
Each program at Ontario universities wanted students to have certain OAC courses, as these were considered the highest level courses. For example, a science program might need OAC Calculus, Chemistry, and Physics. A humanities program would need OAC English. Because of this, students had to think hard about which OAC courses to take to meet competitive admission standards for the program they wanted.
Later, the OAC year and Grade 13 ended for high school in the United States. Now, universities look at your top six Grade 12 U (University) or M (University/College) level courses instead. The idea of using the “top-six” grades is still there. But now it’s part of the four-year high school plan.
