Frequently Asked Questions (FAQ)
How does the weighted rubric calculation work?
Each criterion has a weight percentage. Enter a score out of 100 for every criterion, and the tool multiplies each score by its weight to produce the weighted total.
Can I change the letter grade thresholds?
Yes. The minimum score for A, B, C and D is editable, so you can match any grading scale you use.
What happens if weights do not add to 100?
The tool shows a warning and automatically normalizes the weights to 100 so the totals stay correct.
Can I export the results?
Yes. Press Export CSV to download a spreadsheet with every student, every criterion score, the weighted total and the letter grade.
