Rules as of Ontario PPM 53 (14 April 2009). Last reviewed 2026-11-05.
Rule set: Ontario PPM 53 (14 April 2009). Enter your eligible Grade 12 courses: most are worth 1 credit.
Enter English or anglais, not both, and French as a second language or français, not both: PPM 53 counts only one of each pair.
Rule set: Ontario PPM 53
Total = sum(mark × credit value) over the highest marks that make six credits. Ontario Scholar: 480 or more.
Rules as of Ontario PPM 53 (14 April 2009). Status: confirmed against Government of Ontario, Ministry of Education: Policy/Program Memorandum 53: Ontario Scholar program (14 April 2009) on 4 November 2026.
- Eligible: Grade 12 university, university/college, college, workplace and open courses, locally developed ones included; cooperative education courses related to any of these; dual credit courses in ministry-approved college-delivered programs; OACs (Ontario Academic Courses).
- The principal must recommend the student for the OSSD in the current or the previous school year.
- PPM 53 does not say how to pick when courses carry half or several credits. GradeCat takes the courses worth exactly six credits with the largest total; with one-credit courses only, that is the six highest marks.
- The average is the total ÷ 6. It is GradeCat's arithmetic, because PPM 53 sets only the 480 total, and each university sets its own "top 6" admission average.

How to use this calculator
- Enter each eligible Grade 12 course's final mark. Names are optional. Add course gives you more rows.
- Leave the credit value at 1 for a normal course. Change it for a half-credit course (0.5) or a co-op worth 2.
- Enter every course you have: the tool picks the highest marks that make six credits and lists the ones left out.
The Ontario Scholar rule
Ontario's Policy/Program Memorandum 53 (14 April 2009) defines an Ontario Scholar. The student needs at least 480 marks in eligible courses that total six credits, and the principal's recommendation for the OSSD in the current or the previous school year.
Total = sum(mark × credit value) over the highest marks that make six credits
- Eligible courses: Grade 12 university, university/college, college, workplace and open courses (locally developed ones too), related co-op, dual credits and OACs.
- English or anglais may count, but not both. The same goes for French as a second language and français.
- With more than six credits, the highest marks are used.
Worked example: 502, an Ontario Scholar
This made-up example comes from GradeCat's research on PPM 53: seven one-credit courses.
| Mark (%) | Credits | Counted |
|---|---|---|
| 92 | 1 | Yes |
| 88 | 1 | Yes |
| 85 | 1 | Yes |
| 81 | 1 | Yes |
| 79 | 1 | Yes |
| 77 | 1 | Yes |
| 70 | 1 | No |
92 + 88 + 85 + 81 + 79 + 77 = 502. The 70 is left out, because six higher marks already make six credits. 502 is at least 480, so the student qualifies. The average is 502 ÷ 6 = 83.7.
Half credits and co-op
Each mark is multiplied by its credit value, so a two-credit co-op at 90 adds 180 and fills two of the six credits. PPM 53 does not say how to choose when credits are not all 1. GradeCat takes the courses worth exactly six credits with the largest total. With one-credit courses only, that is just your six highest marks.
Is this my university admission average?
Not always. PPM 53 sets only the 480 total. The average here is that total divided by six, which is GradeCat's arithmetic. Each university sets its own "top 6" admission average, and GradeCat has not checked those rules, so check your university's admission page.
Top 6 average FAQ
How do I calculate my top 6 average in Ontario?
Add your six highest Grade 12 marks, each multiplied by its credit value, then divide by six. Marks of 92, 88, 85, 81, 79 and 77 add up to 502, and 502 ÷ 6 = 83.7.
What average makes you an Ontario Scholar?
A total of at least 480 over six credits, which is an average of 80. You also need the principal's recommendation for the OSSD.
Which courses count?
Grade 12 university, university/college, college, workplace and open courses, related co-op, dual credits and OACs. A Grade 11 course is not on PPM 53's list.
Can English and anglais both count?
No. PPM 53 counts one or the other, and the same goes for French as a second language and français.
Is the Ontario Scholar total the same as a university top 6?
No. Each university sets its own admission average. Use this total for the Ontario Scholar check.
