US High School Grading
US high schools calculate GPA on both an unweighted 4.0 scale and a weighted 5.0 scale that adds bonus points for AP, IB, and Honors courses. Class rank is derived from cumulative GPA and reported numerically or by percentage. College admissions offices review both weighted and unweighted GPA alongside the strength of the course curriculum, making accurate GPA computation a critical function of high school academic records systems.
Unweighted 4.0 Grade Scale
The unweighted scale treats all courses equally regardless of rigor. A to F letter grades map to 4.0 through 0.0 grade points.
| Grade | Grade Points | Percentage Range | Notes |
|---|---|---|---|
| A | 4.0 | 90–100% | Top grade on unweighted scale. Same value whether earned in a standard or AP course. |
| B | 3.0 | 80–89% | Above-average unweighted GPA band. |
| C | 2.0 | 70–79% | Average. Meets most minimum graduation requirements. |
| D | 1.0 | 60–69% | Below average. May not satisfy course prerequisites for subsequent coursework. |
| F | 0.0 | Below 60% | Fail. No credit earned. Course must be repeated for graduation credit. |
Weighted GPA: Course-Type Bonus Points
Weighted GPA rewards academic rigor. AP and IB HL courses typically add 1.0 to the standard grade point; Honors courses add 0.5.
AP (Advanced Placement)
+1.0 grade pointAn A in AP Calculus = 5.0 (weighted) vs 4.0 (unweighted)
AP courses are administered by College Board and can earn college credit via the AP exam. Most high schools add 1.0 to the grade point for A-level performance in AP courses. The weighted scale therefore runs from 1.0 (D in standard) to 5.0 (A in AP).
IB (International Baccalaureate)
+1.0 grade point (HL), +0.5 (SL)An A in IB HL Biology = 5.0 weighted; IB SL = 4.5 weighted
IB Higher Level (HL) courses receive the same +1.0 bonus as AP. IB Standard Level (SL) courses typically receive +0.5 at many schools, though policies vary by district. Full IB Diploma candidates typically carry 3-4 HL and 2-3 SL courses simultaneously.
Honors Courses
+0.5 grade point (most schools)An A in Honors English = 4.5 weighted
Honors courses are rigorous versions of standard courses without the external exam component of AP or IB. The typical bonus is +0.5 grade points. Honors courses are offered at nearly all US high schools and serve as a stepping stone to AP/IB level work.
Dual Enrollment (College Courses)
+0.5 to +1.0 (varies by district)Policy varies widely by state and school district
Dual enrollment courses (college courses taken while still in high school) are treated with varying weight policies. Some districts treat them as equivalent to AP (+ 1.0), others at honors level (+0.5). Students earn both high school and college credit simultaneously.
How OpenEduCat Supports US High School Grading
Weighted and unweighted GPA, class rank, NHS eligibility, and college application transcripts, built for US high schools and K-12 institutions.
Unweighted and weighted GPA computation
OpenEduCat computes both unweighted (4.0 scale) and weighted (5.0 scale) GPA simultaneously for each student. Course types are tagged at setup (standard, honors, AP, IB HL, IB SL, dual enrollment) and the bonus grade point is applied automatically per the district policy configuration. Both GPAs are printed on the official transcript and available in student-facing portals.
Class rank calculation (percentage and numerical)
OpenEduCat supports two class rank methods: numerical rank (student ranked 1st, 2nd, 3rd... out of N in the graduating class) and percentage rank (student falls in top X% of the class). Counselors can configure whether rank is computed on weighted or unweighted GPA, or whether class rank is withheld (an increasing number of districts have moved to rank-optional policies). Class rank is automatically recomputed each grading period.
National Honor Society (NHS) eligibility tracking
The National Honor Society minimum GPA is typically 3.5 unweighted (some chapters require 3.0 or 3.65, configurable). OpenEduCat tracks NHS GPA eligibility per student alongside character, leadership, and service criteria tracked via activity records. Guidance counselors receive a filtered list of NHS-eligible students at the end of each grading period.
College application transcript preparation
OpenEduCat generates transcripts formatted for the Common Application, Coalition Application, and direct college submissions, including both weighted and unweighted GPA, class rank (or rank-withheld notation), AP/IB course listings, and cumulative credits. Counselor recommendation letter templates integrate directly with the transcript export for streamlined college application support.
