CRNA School GPA: The 4 Numbers Programs Calculate

Updated August 2026

CRNA programs calculate four different GPAs: cumulative, science, last 60 credits, and nursing-specific. Programs disagree about which one matters, and because NursingCAS counts both attempts of any retaken class, your application GPA is usually lower than your transcript GPA.

There is no single CRNA school GPA. There are four, programs disagree about which one matters, and the number your application actually shows is usually lower than the one on your transcript. I teach a whole lesson on this inside the membership because it is the single most misunderstood part of an application, and getting it wrong costs people an entire cycle.

So let's go through what programs actually calculate, and the one mechanism that quietly sinks people who retake classes.

What are the four types of GPA CRNA programs evaluate?

When a program says "minimum 3.0," they are not all talking about the same 3.0. Most programs focus on one or two of these four, and knowing which one a school reads changes your entire target list.

1. Cumulative GPA

Every credit you have ever earned, at every institution. Associate degree, bachelor's, post-bacc, that semester you'd rather forget. All of it.

This is the number most people mean when they say "my GPA," and it's the least forgiving one if you had a rough start. An associate's at 2.8 followed by a BSN at 3.0 keeps dragging even after you do well later.

2. Science GPA

Only your science prerequisites. And here's where it gets frustrating: every program defines "science" differently. Anatomy, physiology, and chemistry are in the core basically everywhere. After that it's a coin flip.

Same transcript. Three different science GPAs. If pharmacology was your best grade, Midwestern reads you better than Kansas does, and that is a real strategic input rather than a trivia point.

3. Last 60 credits

Your most recent 60 credit hours only. This is the one that rescues people. A 3.2 cumulative with a 3.7 in your last 60 tells a completely different story, and the programs that weight this are the ones to target if your early transcript is the problem.

4. Nursing-specific GPA

Only your nursing coursework. Useful if you were a stronger nursing student than a general-education one, which is more common than you'd think.

Does NursingCAS use grade replacement?

This is the part I most want you to take away, because it's counterintuitive and it's expensive.

Many universities have grade replacement. You retake a class, the new grade replaces the old one, your transcript GPA goes up. Great.

NursingCAS does not honor grade replacement. It counts both attempts.

So if your school replaced that C+ with an A, your transcript shows the A, and your NursingCAS GPA still carries both. Your application GPA will almost always be lower than the number you've been telling people. People build entire retake plans around a figure programs never see.

A few other things NursingCAS does that surprise applicants:

• It converts every grade to a standard 4.0 scale, so a B+ at your school may not weigh the same as a B+ at someone else's.
• It generates cumulative, science, non-science, and per-institution GPAs separately, and programs pick whichever they prefer.
• Transfer credits count at the grade you originally earned, not the "T" or "CR" your receiving transcript shows.

Before you plan anything, recalculate assuming both attempts count. That is your real number.

Does retaking a class actually raise your GPA?

Barely. And this surprises people who are about to spend a lot of money.

If you've finished a bachelor's, you have 120-plus credit hours on your record. An A in one 4-credit class moves your cumulative GPA by hundredths of a point. As a GPA strategy, retaking one or two courses is close to pointless.

But that was never really the point. You retake a class to show an admissions committee that the C+ from four years ago isn't who you are now. You've grown up, you've learned to study while working nights in an ICU, and you can earn an A in the same subject that beat you the first time. That story does more work than the arithmetic ever will.

If you're weighing a specific grade, we go through the decision in more detail in should you retake a B or C in a CRNA prerequisite.

Where does your GPA actually stand?

The average accepted CRNA student sits around 3.5 to 3.6. Below that isn't a rejection. It just means the rest of your application has to carry more.

• 3.5 and up. You're at or above average. Your GPA is a strength. Make sure everything else keeps pace.
• 3.2 to 3.4. Competitive but on the lower end. Retake weak sciences, consider a graduate-level course, and lean on CCRN and leadership.
• Below 3.2. This is a known weakness, so target programs that read last-60 or nursing GPA. Retake multiple sciences, ideally at least one at the graduate level, and be excellent everywhere else.

How do you audit your own GPA?

This is the process I walk members through, and you can do it yourself in an afternoon:

1. Pull official transcripts from every institution you've attended. All of them.
2. Calculate four numbers: cumulative, science (use the broadest definition), last 60 credits, and nursing-only.
3. Flag every core science below a B.
4. Flag every science course older than 5 years.
5. For each target program, look up which GPA type they use, which courses they count as science, and whether prerequisites expire.
6. Recalculate your NursingCAS GPA counting both attempts of anything you retook.
7. Build your retake plan around the GPA type your targets actually read.

Step 5 is the one people skip, and it's the one that determines whether your list is realistic.

Our Final Thoughts

If you take one thing from this: find out which GPA your target programs read before you spend a dollar on a retake. I've watched people retake chemistry to fix a cumulative GPA at schools that only looked at the last 60 credits. Same money, same semester, zero effect on the number that mattered.

Audit first. Then decide. It's a boring afternoon that saves you a year.
