🧪 Rubric Design Simulation

Design a scoring rubric and watch grading consistency in 3D: tune descriptor specificity, performance-level count and grader count, then re-grade the same work sample and see inter-rater agreement rise or collapse.

Rubric quality is invisible until different graders use it on the same work — this simulator makes that gap visible. A five-criterion rubric (Content, Organization, Evidence, Mechanics, Analysis) is scored by a panel of independent virtual graders against a fixed work sample with a hidden true quality level per criterion. Tune descriptor specificity, the number of performance levels, and the number of graders, then re-grade to see each grader's score scatter in 3D around the gold target ring — tight clusters mean a well-designed rubric, wide scatter means the wording is too vague to grade consistently. Live readouts track pairwise inter-rater agreement, mean deviation from the true score, and the resulting class composite grade.

⚙ Under the hood

This simulation demonstrates the creation of rubrics for evaluating student performance. It illustrates how clearly defined criteria can ensure consistent and objective assessment across different assignments and projects.
