Make This Summer Count

Summer school at OES is 100% online, self-paced, and Ministry-inspected (BSID #667186), covering credits from Grade 9 through Grade 12. There are no fixed start dates — you enroll any day and begin immediately, working with an Ontario Certified Teacher. Students use it to upgrade marks, complete prerequisites for post-secondary admission, retake a course, fast-track their diploma, or resolve timetable conflicts with their day school.

It starts whenever you do. OES summer courses have no fixed start dates — you can enroll today and begin the same day, then work through the material at your own pace. That means you don’t have to wait for a July session to open or worry about missing a registration cutoff, and you can spread the work across the whole summer or compress it into a few weeks.

You can finish an OES summer course in as little as 4 weeks. Courses are self-paced, so motivated students — especially those upgrading a course they’ve already seen — can move quickly, while others can take the full summer. Students working against an admission deadline can also add OES’s Fast Track service, which prioritizes grading and report processing.

Yes. Upgrading marks is one of the most common reasons students take OES summer school. The 4-week upgrade format is optimized for students who have seen the material before, allowing a faster pace through English, math, and science courses. Ontario universities and colleges use your highest mark, so a summer retake can directly raise your admission average before fall applications.

Yes. OES sends your updated marks directly to OUAC, OCAS, and your home school, so your transcript is ready for the fall. If you’re still enrolled at a day school, your summer credit is added to your Ontario Student Transcript; if you’ve graduated, OES manages your transcript and reports your mark to the application centres itself.

Yes. Many OES summer students take a course to get ahead — earning a prerequisite early, lightening next year’s timetable, or freeing space for a spare or an extra Grade 12 course. Because courses are online and self-paced, you can fit a get-ahead credit around a summer job, sports, or travel without conflicting with your day-school schedule.

Yes, through Reach Ahead. Grade 8 students, or students who have just finished Grade 8, can earn OSSD credits with OES before starting secondary school. Reach Ahead has specific eligibility and consultation requirements, so review those with OES and your school before registering. It’s a popular way to enter Grade 9 with a credit already earned.

Yes. OES summer courses are fully online with no scheduled class times, so you can study while travelling or living overseas and still earn Ontario credits — or the full OSSD — from anywhere in the world. You need only an internet connection; assessments, teacher support, and transcript reporting are all handled remotely.

An OES summer course costs the same as a standard OES course. There are no textbook shipping surprises for most courses, and free 24/7 tutoring is included. Check the School Fees page for the current rate and any available discounts.

Yes. Ontario students who started Grade 9 in the 2020–21 school year or later must earn at least two online learning credits to graduate, and a summer course at OES — a Ministry-inspected online school (BSID #667186) — counts toward that requirement. An opt-out process exists through school boards, and specific provisions apply to students affected by the 2021 school closures.
