Science GPA for CRNA school: what counts, and who checks it
67 of 154 accredited programs evaluate it separately from your cumulative
Last updated:
Quick Answer
What is a science GPA for CRNA school?
Your science GPA is calculated from your prerequisite science coursework, and 67 of 154 accredited CRNA programs evaluate it separately from your cumulative GPA. There is no single national definition of which courses count. In practice it is the prerequisites each program names: statistics is required by 84 programs, general chemistry by 67, and anatomy by 50. Because the course list differs by program, your science GPA is not one number — it changes depending on who is calculating it.

Most GPA advice stops at "aim for a 3.5". That is not what applicants actually ask us.
The real questions are narrower: does statistics count, which classes go into the
number, and is it worth retaking anything. Those have answers, and they differ by
program.
There is no national definition. In practice, your science GPA is calculated from the
science prerequisites each program names, which is why the same transcript produces a
different number at different schools. Here is how often each course is required
across 154 accredited programs.

Counts reflect programs that explicitly name the course as a prerequisite. A program
not listed as requiring a course may still count it if you took it.
Which programs actually evaluate a science GPA?
Not all of them, and this is the part that changes where you should apply. Programs
evaluate GPA in four different ways, and many use more than one.
98
evaluate a cumulative GPA
67
evaluate a separate science GPA
52
evaluate a nursing GPA
26
evaluate your last 60 credits
The last-60 group matters if your early coursework dragged your cumulative down. Those
26 programs are effectively giving you a second chance at a first
impression, and applicants with a rough freshman year should be building their target
list around them. The median published minimum across all 154 programs is
3.0.
Does statistics count as a science course?
Usually yes. Statistics is the single most commonly required prerequisite we track,
named by 84 of 154 programs, and schools that require it generally fold it
into the science calculation.
This matters more than it sounds. A science GPA is computed over a handful of courses,
so one weak grade carries far more weight than it would in a cumulative built from 120
credits. If statistics is the C on your transcript, it is disproportionately worth
fixing.
Is it worth retaking a science class?
Sometimes, and the deciding factor is which GPA the retake actually moves. A retake
that lifts a science GPA calculated over six courses is worth a semester. The same
retake against a cumulative GPA of 120-plus credits barely registers.
Before enrolling, check two things: whether the program replaces the original grade or
averages both attempts, and whether it counts the course in its science calculation at
all. Both vary, and neither is safe to assume.
If you have not separated the two numbers yet, do that first. Most applicants have
only ever seen their cumulative, and the
free Transcript
Analyzer will calculate both from an uploaded transcript.
Do CRNA prerequisites expire?
At 30 of 154 programs, yes. Expiry windows are typically five to ten years
and fall most often on chemistry and statistics.
This is one of the least consistently published requirements in the whole application,
and it catches career changers hardest. A chemistry course from ten years ago can be
perfectly acceptable at one program and require a retake at the school next door. It
is worth checking on a per-program basis rather than assuming a norm exists.
Frequently Asked Questions
Does statistics count toward your science GPA for CRNA school?
Usually yes, and it is the most commonly required prerequisite we track: 84 of 154 accredited programs require statistics. Whether it lands in the "science" bucket depends on the program's own definition, and not every school publishes one. Programs that name statistics as a science prerequisite are almost always folding it into the science GPA they calculate. If your statistics grade is weak and your target programs count it, that single course can move the number more than you expect, because science GPAs are usually computed across a small set of classes.
What is the difference between science GPA and cumulative GPA for CRNA school?
Cumulative is every course you have ever taken; science GPA is only the prerequisite science coursework. They diverge more than applicants expect, because science GPA is computed over a handful of classes so a single C moves it substantially. Of 154 accredited programs, 98 evaluate a cumulative GPA and 67 evaluate a separate science GPA — many do both. A further 26 look at your last 60 credit hours instead, which is the friendliest calculation if your early coursework was weak.
Which courses are included in a CRNA science GPA?
There is no national standard, which is the honest answer most sites avoid. It is whichever science prerequisites the program names. Across 154 accredited programs the most commonly required are statistics (84), general chemistry (67), anatomy (50), and organic chemistry (32). Biochemistry (7) and physics (7) appear far less often. Because the list differs, your science GPA is genuinely a different number at different schools, and it is worth calculating it separately for each of your targets.
Does retaking a science class improve your CRNA school GPA?
It depends on whether the program replaces the grade or averages both attempts, and policies differ. Retaking helps most when the course is one of a small number in the science calculation, since the weight per course is high. It helps least on a cumulative GPA built from 120-plus credits, where one retake barely registers. Before you enrol and pay, check whether your target programs count the retake at all. The CRNA Club's free Transcript Analyzer calculates your cumulative and science GPAs separately from an uploaded transcript so you can see which one is actually holding you back.
Do CRNA prerequisite courses expire?
Yes, at 30 of 154 accredited programs, which publish an expiry window on prerequisite coursework, typically five to ten years, most often on chemistry and statistics. The rest either accept coursework of any age or do not state a policy. This catches career changers and second-degree applicants most often: a chemistry course from a decade ago can be fine at one program and require a retake at another. Check the specific programs on your list rather than assuming, since this is one of the least consistently published requirements we track.
