R Notation Ontario Transcript: What It Means After Repeating a Course

If you retake a Grade 11 or 12 course in Ontario, an R notation shows up on your Ontario transcript next to the lower of your two marks. The R stands for Repeat, and it sits in the credit column beside whichever attempt scored less. Only the higher mark earns the 1.0 credit toward your Ontario Secondary School Diploma (OSSD). Both attempts, and both marks, stay on your Ontario Student Transcript (OST) permanently once recorded. This guide breaks down exactly how that looks with real sample marks, and how it changes your university admission average.

Quick Answer: When you repeat or upgrade a Grade 11 or 12 course in Ontario, both attempts appear on your Ontario Student Transcript (OST) with both percentage marks listed side by side. An “R,” for Repeat, sits in the credit column next to the lower mark, showing it did not earn credit. Only the higher mark counts toward the 1.0 credit needed for your Ontario Secondary School Diploma (OSSD). You still earn just one credit total for that course code, no matter how many times you take it. Universities calculating your admission average generally use the higher, credit-bearing mark, though some programs may still see the lower mark through full disclosure.

Key Highlights of R Notation Ontario Transcript

• The R notation only applies to Grade 11 and 12 courses, under Ontario’s full disclosure policy.
• Both attempts and both percentage marks stay on your OST permanently, side by side.
• The “R” sits in the credit column next to the lower mark, not the higher one.
• Only the higher mark earns the 1.0 credit toward your OSSD (Ontario Secondary School Diploma).
• You earn one credit total per course code, regardless of how many times you retake it.
• Universities generally use the higher mark for admission average calculations, but confirm with each program.
• The R notation works the same way whether you are repeating a failed course or upgrading a passed one.

What the R Notation Actually Is

The R notation is a single letter, “R,” placed in the credit column of your Ontario Student Transcript (OST) next to a repeated course’s lower mark. It tells anyone reading your transcript that this specific attempt did not earn diploma credit. Ontario Student Transcript Manual guidance used across Ontario school boards, including the Toronto District School Board’s published OST Manual, describes the R notation as the standard flag for a non-credit repeat attempt.

The letter itself is simple, but what it represents matters. It is not a penalty mark or a demerit against you. It is a bookkeeping flag that keeps your transcript accurate once a course code appears more than once.

Students sometimes assume the R means the mark was cancelled or erased. That is not correct. The mark still shows in full. Only the credit value tied to that specific attempt changes.

When the R Notation Actually Shows Up

The R notation appears any time a Grade 11 or 12 course code is attempted more than once, whatever the reason for the second attempt. USCA Academy’s comparison of credit recovery, course upgrades, and repeating a course breaks down those three paths in detail, but the transcript result is identical across all three.

A student who failed a course and retakes it in full gets an R notation next to the failing mark, once the higher, passing mark is also recorded. A student who already passed a course but retakes it purely to raise the mark, commonly called an upgrade, gets the same R notation next to the original, lower passing mark. The transcript does not record your motive. It only records that the course code appears twice, and flags the lower entry.

This is a direct extension of Ontario’s full disclosure policy. As explained in USCA Academy’s guide to Ontario’s full disclosure policy, every Grade 11 and 12 course attempt is recorded, whether it was completed, failed, or withdrawn from after the drop deadline. According to the Ontario Ministry of Education’s Ontario Schools, Kindergarten to Grade 12 policy document, this rule has applied since September 1999. Repeating or upgrading a course does not get you around it. It simply adds a second, equally permanent, entry.

Worked Example: From 58% to 82% on the Same Course Code

Here is how this plays out with real numbers. Picture a student, Priya, taking SPH4U, Grade 12 Physics, in the first semester of Grade 12. She passes with a 58%. That mark earns her the 1.0 credit and appears on her OST as a normal, completed course.

Priya wants a stronger physics mark for an engineering program’s admission average. She enrolls in SPH4U again the following semester as a course upgrade, not because she failed, but because she already holds the credit and wants a better number. This time she scores 82%. Her OST now shows SPH4U twice, with both marks listed.

The table below shows exactly how those two attempts appear once the second mark is recorded.

The 58% entry does not disappear and it is not crossed out. It stays on the OST permanently, with the R sitting in the credit column beside it, but it no longer contributes credit. Priya’s official diploma credit count reflects only the 82% attempt’s 1.0 credit. Her total remains one credit for SPH4U, not two, even though two transcript lines now exist for that course code.

If Priya had failed her first attempt instead of passing it with 58%, the transcript mechanics would look identical. The only difference is what you call the retake. A retake after a fail is usually called a repeat, and a retake after a pass is usually called an upgrade. Either way, the R sits next to the lower mark and the higher mark carries the credit.

Why Only the Higher Mark Counts Toward Your OSSD

Your Ontario Secondary School Diploma (OSSD) requires 30 credits, and each course code can only ever contribute one of them. If both attempts at SPH4U earned separate credits, students could accumulate extra diploma credits simply by retaking courses, which is not how the credit system is designed to work.

By assigning the R notation to the lower mark and the credit to the higher one, the OST keeps a clean, honest count. You get full benefit of your best performance in that course, and the transcript still shows the complete history of how you got there. Nothing about this process changes the total number of credits you need to graduate.

This also means a course upgrade or repeat cannot be used to “stack” credits toward your 30-credit total. The purpose of retaking a course is a better mark, not extra credits. That distinction matters when a student is weighing whether an upgrade is worth the time investment.

How the R Notation Interacts With Your University Admission Average

This is where the R notation matters most for university-bound students. Ontario universities calculate an admission average from a student’s top six Grade 12 university (U) or university/college (M) course marks. According to the Ontario Universities’ Application Centre (OUAC), when a course code has two attempts on file, universities generally use the higher, credit-bearing mark for that calculation, since that is the mark tied to the OSSD credit.

USCA Academy’s guide on how to calculate your Ontario university admission average walks through the full top-6 calculation in detail. Here is how Priya’s upgraded SPH4U mark fits into that kind of calculation, using her 82% rather than her original 58%.

Adding those six marks gives 502, and dividing by six gives an admission average of 83.7%. Had Priya’s admissions calculation used her original 58% instead of the 82% upgrade, her average would have dropped to 79.7%, a full 4 percentage points lower from one course alone. That is the practical weight a single upgrade can carry.

Do not treat this as a universal guarantee across every program. Individual programs can still review both marks if full disclosure shows a repeat or upgrade, particularly in competitive, holistic-review programs like health sciences or engineering. Confirm directly with each university’s admissions office how they treat a repeated course code before you assume only the higher mark will be considered.

This is also why timing matters so much for an upgrade. A student targeting an OUAC application deadline in January needs the second attempt’s final mark submitted before that cutoff. Retaking SPH4U in a summer term ahead of Grade 12, rather than waiting for the second semester of Grade 12 itself, can give a guidance counsellor more room to confirm the mark before submission.

R Notation Compared to Other Transcript Entries

It helps to know what the R notation is not. A withdrawal from a course after the drop deadline is recorded with a different notation, often a “W,” and does not involve a second attempt at all. The R notation specifically requires two attempts at the same course code, with one mark higher than the other.

The R also should not be confused with a failing grade notation. A student can fail a course, retake it, and pass, or a student can pass a course twice and simply improve the mark. In both cases the R sits next to the lower number, whether that lower number was a fail or just a weaker pass.

A course taken only once, with no retake at all, carries no special notation in the credit column at all. The R notation only ever appears once a second attempt at the same course code exists on file. A single, one-time attempt at a course, whatever the mark, is simply recorded as a normal completed or failed course.

Honest Tradeoffs: What the R Notation Costs You

Retaking a course is not free of downsides, and pretending otherwise does not help a student plan well. The R notation and the lower mark stay on your OST permanently once recorded for a Grade 11 or 12 course. There is no process to remove either one later, even after you graduate.

There is also a real dollar cost to weigh. A regular credit course typically runs $490 to $574 depending on grade and year, while a summer school credit course runs closer to $750. Spending that on a course upgrade only makes sense if the expected mark gain is large enough to matter for the programs a student is actually targeting.

A course upgrade also costs real time and tuition for a mark gain that might be modest. Priya’s 24-point swing, worth a full 4 points on her admission average, is a strong case for upgrading. A student moving from 78% to 81% on a course that is not in their top six admission-average courses gains almost nothing for the time spent, since that small gain barely moves the six-course average at all.

There is also a visibility cost worth naming honestly. While most admissions offices use only the higher mark for the numeric average, the lower mark and the R notation remain visible on the full transcript. Competitive programs conducting a holistic file review can still see that a course was repeated, even if their formula does not count the lower number.

Weigh the expected mark improvement against the time, cost, and visibility before committing to an upgrade or repeat. A guidance counsellor who knows your current marks and target programs can help you judge whether a specific course is worth retaking.

Where the R Notation Fits Into USCA Academy’s Programs

Because R notation decisions are permanent once recorded, timing and course selection matter enormously. USCA Academy keeps class sizes between 5 and 15 students specifically so the guidance team can walk a student through whether a repeat or upgrade is worth pursuing before they commit a semester to it.

Students planning a course upgrade for OUAC (Ontario Universities’ Application Centre) purposes often use USCA’s night school program in Mississauga, which lets them retake a course in the evening while keeping their regular daytime timetable intact. USCA’s summer school program offers a faster, compressed option, with two intakes in July and August 2026 at $750 per credit course.

Regular credit courses, available online and in person for $490 to $574 depending on grade and year, can also be used to repeat or upgrade a course outside the summer window. USCA’s Grade 12 course listings and full course catalogue show which specific courses are available for an upgrade heading into OUAC deadlines.

For students building a strategy around admission averages, USCA’s University Preparation Program and OUAC application guidance help confirm that the timing of an upgrade lines up with submission deadlines. If the goal is closing content gaps rather than just scheduling a retake, USCA’s tutoring program can run alongside night school or summer school to make the upgrade attempt more likely to succeed.
