LLM-as-a-Grader for Short-Answer and Report Evaluation

This is like having an always-available teaching assistant that reads students’ short answers and reports, compares them to a grading guide, and suggests scores and feedback so instructors don’t have to grade everything by hand.

Executive Brief

Business Problem Solved

Manual grading of short answers, essays, and reports is slow, expensive, and inconsistent across graders. Using a large language model as an automated grader can dramatically cut grading time while providing more consistent scoring and structured feedback to students.

Value Drivers

Cost reduction in grading labor (fewer TA hours, less instructor time)Faster turnaround of grades and feedback for studentsMore consistent grading against rubrics across large classesScalable assessment for MOOCs and large-enrollment coursesPotential support for formative feedback before final submission

Strategic Moat

If deployed as a product, the moat would come from proprietary grading rubrics, historical labeled data (human-graded answers), integration into LMS workflows, and validated alignment with institutional assessment standards rather than from the underlying LLM itself.

Differentiation Factor

Focus on using LLMs specifically as automated graders for short-answer and report-style assignments, with attention to practical evaluation protocols and reliability, rather than generic essay scoring or generic chat-based tutoring.
