What does a score of 0–4 represent?

The 0–4 scale maps to: 0 = Missing/No evidence, 1 = Beginning, 2 = Developing, 3 = Proficient, 4 = Exemplary. This is the most common rubric scale in K–12 and higher education.

How is the weighted score calculated?

Each criterion's contribution = (score / 4) × weight. The total weighted score is the sum of all contributions. The percentage is (total earned / total possible) × 100.

What letter grade scale does this use?

Standard US scale: A (90–100%), B (80–89%), C (70–79%), D (60–69%), F (below 60%).

Can I change the weights for each criterion?

Yes. Each criterion has its own weight field. Higher weights make that criterion count more toward the final grade.

Is there a minimum number of criteria required?

No. The calculator works with as few as one criterion. You can add up to 8 criteria total.
