Grid Professor Grader

Grid Professor Grader is built for instructors who teach modeling in Excel and want grading that keeps pace with the classroom. It grades student work live, cell by cell, and records how each answer was reached, so you can reward genuine modeling work instead of just a correct final number.

Instant, per-cell grading. As students enter answers, correct cells are highlighted automatically and a progress bar in the task pane shows how many are right. Each assignment can run in a practice mode with visible feedback, or a no-feedback mode for quizzes and competitions.

Every assignment, twenty ways. Each assignment carries twenty parameter sets, and students must build a model that works across all of them. Neighbors get different scenarios, so a shared answer is useless. Grading validates the model, not a single hard-coded value.

Designed for academic integrity. A final workbook looks the same whether a student built it or pasted it from an AI tool. Grid Professor Grader captures a complete, timestamped log of the work, edits, selections, and progress, so an answer that appears with no supporting work is visible.

A live view of the whole class. Instructors get a real-time scoreboard, per-student and per-question results, engagement reporting, and one-click CSV export for the gradebook.

Works where you already teach. Grid Professor Grader runs in Excel on Windows, Mac, and the web. Students sign in with an authorized account and open the assignment workbook their instructor provides.

Getting an account. Grid Professor Grader is provided to students and faculty through their school, college or university, so accounts are set up for a class rather than signed up for individually. Students are enrolled by their instructor and then sign in through the task pane with the email address their institution uses.

Instructors and departments can request access by emailing admin@gridprof.com with their institution, the course, and approximate class size. Full details are at https://app.gridprof.com/access.html
