Calculating Your PostBacCAS GPAs

This page applies to: PostBacCAS

GPA Types

During Verification, PostBacCAS uses the information you entered in the Transcript Entry section to calculate GPAs for each institution (school) you attended. To calculate these GPAs, each A-F or 0-100 grade you entered in the Grade field is first converted to a PostBacCAS numeric grade value, then multiplied by the attempted credits. The resulting product is Quality Points

Your total Quality Points are then divided by your total Attempted Credits to determine your school GPA. 

Example:

Course Transcript Grade Converted Numeric Grade Value Attempted Credits  Calculation Quality Points
MATH 1100 A 4 4 4 x 4 16
ENGL 1310 B 3 3 3 x 3 9
GEOL 1610 C 2 4 2 x 4 8
PHED 1000 D 1 3 1 x 3 3
PSCI 1040 F 0 3 0 x 3 0
Total     17   36
GPA Calculation: 36 (Quality Points) / 17 (Attempted Credits) = 2.12 (GPA)

 

Using Quality Points, PostBacCAS also calculates a GPA for each academic year. GPAs from your Freshman, Sophomore, Junior, and Senior academic years are subsequently:

  1. Combined with any post-baccalaureate coursework to create a cumulative undergraduate GPA, and
  2. Combined with any post-baccalaureate coursework plus any graduate coursework to create an overall GPA. 

 

Year-Level GPA Example:

Year Credits Quality Points GPA
Freshman 66 166.2 2.52
Sophomore 48 119.4 2.49
Junior 66 223.2 3.38
Senior 60 169.2 2.82
Total 240 678 2.83
Post-Baccalaureate 28 112 4.0
Cumulative Undergrad 268 790 2.95
Graduate 66 245.4 3.72
Overall 334 1035.4 3.10

 

Note that PostBacCAS calculates all GPAs in semester hours. Courses that were completed in quarter hours are converted to semester hours. The conversion ratio is 1.0 quarter hour = 0.667 semester hours.

Discrepancies

Because of the standardization that occurs during Verification, it is not uncommon to see GPA discrepancies between what your schools calculate and what PostBacCAS calculates. Discrepancies occur because: 

  • PostBacCAS does not recognize an individual school's policies for forgiveness, academic renewal, or grade replacement for repeated courses. All grades earned for repeated courses are factored into your PostBacCAS GPA.
  • PostBacCAS calculates all GPAs in semester hours. Courses that were completed in quarter hours are converted to semester hours. The conversion ratio is 1.0 quarter hour = 0.667 semester hours.
  • PostBacCAS breaks down your GPA by academic year, so coursework completed at multiple schools for similar academic years get combined. For example, if you completed freshman coursework at College ABC and freshman coursework at College XYZ, PostBacCAS uses all of that coursework to calculate the GPA for your freshman academic year.
