Intelligent Grading Cost Savings Calculator
Measure grading efficiency at scale with quality metrics.
Unlike the teacher-level calculator, this tool measures grading efficiency at the institutional scale. It accounts for multi-section courses with multiple graders, where consistency and turnaround time are as important as raw time savings. Institutions with 50+ faculty members and thousands of assessments per semester face compounding costs from slow feedback cycles, grading inconsistency across sections, and the administrative overhead of managing grading timelines. This calculator quantifies those costs and shows the budget impact of reducing grading turnaround from days to hours while maintaining or improving grading quality and consistency scores.

计算方法
The calculator uses total assessments per semester, number of graders, average grading time per assessment, and current turnaround time in hours. It models AI-assisted grading as reducing per-assessment grading time by 80% for objective formats and 50% for subjective formats, with turnaround dropping from the institutional average (typically 96 hours) to under 1 hour for AI-graded work. Consistency improvement is modeled as the reduction in score variance across graders, benchmarked at 85/100 on a standardized rubric alignment scale. Budget impact is calculated by multiplying total hours saved by the blended hourly rate of grading staff (faculty, TAs, and adjuncts).
