GradePattern: Assignment Rubric Drift Detector
Analyzes grading patterns across assignments to alert teachers when their rubric application becomes inconsistent, helping them catch fairness issues before final grades.
The Problem
Teachers grade hundreds of assignments per semester but their rubric application drifts over time — they unconsciously grade assignment #47 differently than assignment #5 using the same rubric. This creates unfair grade distributions and violates their own grading standards, but they have no visibility into it until students complain or appeal grades.
Target Audience
High school and college teachers (especially in humanities/social sciences where subjective grading is common), teaching assistants, and department heads concerned with grade fairness audits.
Why Now?
Districts are increasingly auditing grade fairness for equity reasons; teachers are overloaded and need AI to catch their own blind spots without adding work.
What's Missing
Existing gradebook software treats grades as final outputs, not as audit trails to analyze for consistency. No tool surfaces when a teacher's 'exceeds expectations' standard shifts mid-semester.
