Teacher Grader

As you type the number of missed questions for each student, the score and letter grade columns update instantly — no clicking required. Class statistics also update in real time.

This grader assumes equal point values per question. For tests with weighted questions, use the Score Calculator and enter each student's total earned points vs. total possible points.

Yes — click "Copy All Results" to copy all student scores to your clipboard in a tab-separated format that you can paste directly into Excel or Google Sheets.

A class average of 75–85% is typically considered healthy — it shows the test was challenging but not impossible. If the average falls below 70%, the test may have been too difficult, or students may need reteaching. Above 90% may suggest the test was too easy. Many teachers curve scores when the class average is below 70%.

Common curving methods: (1) Flat curve — add fixed points to every score (e.g., +5 points). (2) Square root curve — multiply each score by 10, then take the square root (e.g., 64% → √640 ≈ 80%). (3) Scale to top score — divide each score by the highest score and multiply by 100. Enter the curved scores into the grader above to see updated class statistics.

The grader starts with 5 student rows and you can add more with the "Add Student" button. It handles any class size — all processing runs in your browser so there's no server limit. For very large classes (100+ students), pasting into a spreadsheet via "Copy All Results" is faster.
