Formulas Used

Weighted Score (%)

weighted_score = (content_score / 4 * content_weight + organization_score / 4 * organization_weight + presentation_score / 4 * presentation_weight + mechanics_score / 4 * mechanics_weight) / total_weight * 100

Raw Score (out of 4)

raw_total = (content_score * content_weight + organization_score * organization_weight + presentation_score * presentation_weight + mechanics_score * mechanics_weight) / total_weight

Maximum Possible

max_possible = 4

How It Works

How Rubric Scoring Works

A rubric assigns scores (1-4) across criteria, each weighted by importance.

Formula

Weighted Score = Sum(Criteria Score / Max x Weight) / Total Weight x 100

Rubric Scale

  • 4 = Exceeds expectations
  • 3 = Meets expectations
  • 2 = Approaching expectations
  • 1 = Below expectations

    • Worked Example

    Content 3/4 (40%), Organization 3/4 (25%), Presentation 4/4 (20%), Mechanics 3/4 (15%).

    content_score = 3content_weight = 40organization_score = 3organization_weight = 25presentation_score = 4presentation_weight = 20mechanics_score = 3mechanics_weight = 15
    1. 01Content: 3/4 x 40 = 30
    2. 02Organization: 3/4 x 25 = 18.75
    3. 03Presentation: 4/4 x 20 = 20
    4. 04Mechanics: 3/4 x 15 = 11.25
    5. 05Total = (30 + 18.75 + 20 + 11.25) / 100 x 100 = 80%
