How Grading Scales Work
A grading scale is a systematic method developed by teachers or school districts.
Scale Logic
Grade = First Rank where (Score ≥ Minimum %)
- Teachers define the "floor" or minimum percentage required for each letter.
- Students calculate their points earned out of total points possible.
- The scale matches the resulting percentage to the highest possible grade tier.
