The short answer
Collect your final (stored) grades per course, with credits. Then apply your district's method: Simple = average of grade points; Simple Percent = average of percentages; Weighted = credit-weighted grade points plus Honors/AP bonuses; Weighted Percent = credit-weighted percentages. Skip the manual math: the PowerSchool GPA Calculator does all four with your district's bonuses.
Step 1: Use stored grades, not live scores
GPA is computed from stored (finalized) grades — the ones on your transcript — not today's in-progress percentages. Use Grades History (term grades per course) rather than the current term's Class Score Detail.
Step 2: Convert each grade to points
Standard points: A=4, B=3, C=2, D=1, F=0 (plus/minus variants: A−=3.7, B+=3.3, and so on). Your district's scale may differ — AP Calculus and Basic Math can use different scales in the same district. Use your district's table.
Step 3: Apply your district's method
Simple: average the points. A (4.0) + B (3.0), equal weight → 3.50. Weighted: weight by credits and add bonuses. A in AP at 5.0 (with the example +1.0 bonus) + B regular at 3.0 → 4.00. If the method is omitted from a GPA code, PowerSchool uses a method called “weighted.”
Weighted bonuses are district-set
One district's example: A = 4.0 regular, 4.5 honors, 5.0 AP; B = 3.0 / 3.5 / 4.0. Those bonus values are that district's choice, not PowerSchool's rule. Ask your counselor or check your district's grading policy for yours — another district's table may not be yours.
Current vs Cumulative GPA
Cumulative GPA uses stored grades only. Current GPA uses current, not-yet-stored grades — and is always calculated with the simple method. If your “current GPA” looks different from a weighted calculation, the simple-method rule is why. Projected GPA adds projected grades to historical ones.
Common mistakes
- Using live gradebook scores. GPA comes from stored final grades.
- Assuming one bonus table. Honors/AP bonuses are district-set.
- Mixing methods. Simple (3.50) and Weighted (4.00) differ on the same grades.
- Ignoring credits. Weighted methods weight by credit hours; Simple methods don't.
- Expecting the portal to show it. The portal guide documents no GPA display — check reports/transcripts, or compute it here.
