Grade Point Average (GPA)
Definition
Grade Point Average (GPA) is a standardized numerical index that summarizes a student's overall academic performance across completed secondary or collegiate coursework.
Detailed Technical Breakdown
The GPA represents the average number of grade points earned per attempted course credit. In unweighted systems, grades correspond to standardized values from A = 4.0 down to F = 0.0 regardless of course difficulty. In weighted systems, schools award bonus points (typically +0.5 for Honors and +1.0 for AP/IB courses) to reflect academic curriculum rigor. Cumulative GPA is evaluated by universities, scholarship committees, and graduate schools as a primary academic indicator.
Key Technical Specifications
- Standard formula: GPA = Total Quality Points / Total Attempted Credits.
- Unweighted scale: Capped strictly at 4.0 (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0).
- Weighted scale: Scales up to 5.0 for AP and IB courses (A = 5.0, B = 4.0, C = 3.0).
- Quality points equal the numerical grade value multiplied by the course credit hours.
