Does school size affect quality?
That's a fair thing to wonder, especially if you're picturing a big lecture hall versus a small, tight-knit cohort — and the honest answer is that size itself doesn't make a program better or worse. What it does change is how reliable that program's reported outcomes are, particularly published pass rates on licensing exams like the CALE (California Acupuncture Licensing Exam).
Does school size affect quality? — Not directly, but it changes how much you can trust the numbers
That's a fair thing to wonder, especially if you're picturing a big lecture hall versus a small, tight-knit cohort — and the honest answer is that size itself doesn't make a program better or worse. What it does change is how reliable that program's reported outcomes are, particularly published pass rates on licensing exams like the CALE (California Acupuncture Licensing Exam).
Here's why: a pass rate built from a handful of test-takers can swing wildly on one or two results, while a rate built from dozens holds much steadier year over year. Looking at California Acupuncture Board data aggregated by Five Branches University's TCM Education Guide (school's own published analysis, checked 08/2026):
| School | 2021–2025 test-takers (N) | Cumulative pass rate | Pattern |
|---|---|---|---|
| Five Branches University | 169 | 85.8% | Every year in the high-20s to low-40s range — large, consistent cohorts |
| Academy of Chinese Culture & Health Sciences | 88 | 83% | Shrinking cohorts (26→10) with wide swings (69%–94%) |
| California University–Silicon Valley | ~15 | 73.3% | Averages ~2 test-takers/year; one bigger class (7) swung the rate to 42.9% |
A single retake result can move a 2–3 person cohort's percentage by 20–50 points, but only a couple points for a 40-person cohort — so the size of the number underneath the percentage matters as much as the percentage itself.
Separately, class size inside a program is more about learning experience than "quality" in the outcomes sense — for context, other schools publish figures like a 15:1 ratio for hands-on practicum classes, though that's a different measure entirely from exam-outcome reliability, and it isn't something we track for Five Branches specifically.
So the real question worth asking about any school isn't "how big is it" but "how many years of consistent data stand behind its published outcomes." Are you comparing a couple of specific schools, or trying to get a general sense of how to read these numbers?
