CASPA GPA Calculation Explained

The CASPA (Centralized Application Service for Physician Assistants) calculates several distinct GPAs from your undergraduate coursework. Each GPA serves a different purpose in PA school admissions evaluation.

GPA = Total Quality Points ÷ Total Credit Hours
Quality Points = Credit Hours × Grade Point Value

CASPA GPA Categories

  • Overall GPA: All undergraduate courses combined, regardless of subject.
  • Science GPA: Biology, Chemistry, Physics, and Other Science/Math courses.
  • BCP GPA: Biology, Chemistry, and Physics courses only — a focused subset of Science GPA.
  • Non-Science GPA: All courses not classified as Science (English, History, Psychology, etc.).

CASPA uses a standardized grade-to-quality-point conversion scale. All repeated courses are counted fully — CASPA does not replace grades for repeated coursework.

How CASPA GPA Calculation Works

Follow these steps to understand how CASPA computes your application GPAs:

  1. Classify each course by subject category — Determine whether each course is Biology, Chemistry, Physics, Other Science/Math, or Non-Science.
  2. Convert each letter grade to quality points — Use the standard CASPA scale: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, D-=0.7, F=0.0.
  3. Calculate quality points per course — Multiply credit hours by the grade's numeric value. Example: 3-credit B+ = 3 × 3.3 = 9.9 quality points.
  4. Sum quality points and credits by category — Group courses into Overall, Science, BCP, and Non-Science categories and total the quality points and credit hours for each.
  5. Divide to get each GPA — For each category, divide total quality points by total credit hours. This yields each CASPA GPA value.

CASPA GPA Calculation Examples

Example 1: Strong Science Performance

4 courses: General Biology I (A, 4cr, Biology), Gen Chem I (A-, 4cr, Chemistry), English Comp (B+, 3cr, Non-Science), Statistics (B, 3cr, Other Science)

Overall QP: 4×4.0 + 4×3.7 + 3×3.3 + 3×3.0 = 16.0+14.8+9.9+9.0 = 49.7
Overall Credits: 14 → Overall GPA = 49.7/14 = 3.55
Science GPA (Bio+Chem+OtherSci): (16.0+14.8+9.0)/11 = 3.62
BCP GPA (Bio+Chem): (16.0+14.8)/8 = 3.85

Example 2: Balanced Academic Record

4 courses: Organic Chem (B, 4cr, Chemistry), Physics I (B+, 4cr, Physics), Psychology (A-, 3cr, Non-Science), Sociology (A, 3cr, Non-Science)

Overall QP: 4×3.0 + 4×3.3 + 3×3.7 + 3×4.0 = 12.0+13.2+11.1+12.0 = 48.3
Overall Credits: 14 → Overall GPA = 48.3/14 = 3.45
Science GPA (Chem+Physics): (12.0+13.2)/8 = 3.15

People Also Ask

CASPA calculates multiple GPAs by categorizing each undergraduate course as Science or Non-Science. Quality points are computed by multiplying credit hours by the grade's numeric value. Each GPA is the total quality points divided by total credit hours within that category. CASPA reports Overall GPA, Science GPA, BCP GPA, and Non-Science GPA.
Competitive PA school applicants typically have an Overall CASPA GPA of 3.5 or higher and a Science GPA of 3.4 or higher. The most selective programs often look for Overall and Science GPAs above 3.6. Many programs also consider healthcare experience, personal statement, and letters of recommendation.
BCP GPA stands for Biology, Chemistry, and Physics GPA. It is a subset of the Science GPA that includes only courses specifically in Biology, Chemistry, and Physics disciplines. Many PA programs place particular emphasis on BCP GPA as an indicator of readiness for the rigorous science curriculum in PA school.
Yes, CASPA includes Mathematics and Statistics courses in the Science GPA category under "Other Science." Math courses count toward your CASPA Science GPA but are NOT included in the BCP GPA, which only covers Biology, Chemistry, and Physics specifically.
CASPA includes ALL attempts of repeated courses in GPA calculations. Unlike some university GPA systems that replace grades for repeated courses, CASPA counts every attempt. Both the original and repeated course grades contribute quality points and credit hours to your CASPA GPA calculation.

Frequently Asked Questions

This calculator uses the official CASPA grade scale and subject category classifications to provide a close estimate. However, CASPA performs its own official verification and may classify courses differently. Always verify your official CASPA GPA through your application after submission.
Most accredited PA programs require a minimum Overall CASPA GPA of 3.0 for application consideration. Competitive programs typically expect 3.4-3.6 or higher. Science GPA requirements are often similar, with many programs emphasizing BCP performance. Always check specific program requirements.
CASPA calculates graduate GPA separately from undergraduate GPA. Graduate courses do not factor into your undergraduate CASPA GPA. However, strong graduate performance is visible on your application and can demonstrate academic capability to admissions committees.
Other Science includes Mathematics, Statistics, Astronomy, Geology, Environmental Science, Kinesiology, Nutrition, and other natural/physical sciences not classified as Biology, Chemistry, or Physics. These count toward Science GPA but not BCP GPA.
Yes, CASPA uses the full plus/minus grade scale. Each grade variant has a specific quality point value: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, D-=0.7, F=0.0. This means the difference between an A- and a B+ can meaningfully impact your GPA.
AP credits that appear on your college transcript as pass/fail or without a letter grade do not contribute to your CASPA GPA. Only courses with standard letter grades (A-F) that appear on your official transcript are factored into CASPA GPA calculations.
