Compare three grading approaches
Three Ways to Grade
Choose a sample, edit the marks, and compare the results.
The school's algorithm
- A mark has a score (usually 0–6) and an assessment weight (normally ×1).
- Multiply each score by its weight. Divide by the sum of weights (which can be 6 when six marks each weigh ×1).
- Round the average to one decimal. If it matches a Settings entry, use that %; otherwise use the percentage between two entries.
- Competency scores contribute to category scores; category weights combine the category percentages into one course percentage.
- The course percentage determines the overall letter grade.
Evidence pattern
- Within each competency: find the most common proficiency family (mode). Do it for all evidence and separately for the latest five.
- Across competencies: choose the most common selected achievement. With custom competency weights, count weighted votes.
- Median safeguard: when there is no clear mode, or a high mode sits at least two achievement steps above the middle, use the median instead.
- Final: compare Most Consistent and Most Recent, keeping the protected-final rule.
- Percentage: E+ = 98%, E = 94%, P+ = 89%.
Percentage band ruler
- Each assessment level has a ruler rung (1 to 7); weighted marks create a position.
- Ruler band 6, for example, corresponds to 86–93%; all seven bands are displayed below.
- At position 6.25, you are 25% of the way from 86% toward 93%.
- This model uses a continuous numerical ruler to choose the percentage.
