Class gradebook model & example

Run a multi-student weighted gradebook in the browser—category weights, roster scores, class average, and CSV export.

Example: Homework 20%, Quizzes 30%, Exams 50%. Student scores 92 / 88 / 85 → 0.2×92 + 0.3×88 + 0.5×85 = 87.3%.

WHO IT HELPS & HOW TO USE IT

How to use class gradebook

  1. Add or edit weighted categories (homework, quizzes, exams, etc.).
  2. Add students and enter each category score as a percentage.
  3. Read per-student averages, class average, and optionally export CSV.

Before you rely on the result: Local planning tool, not an LMS. One class at a time in this browser tab. Maximum 100 students and 8 categories.

UNDERSTAND YOUR RESULT

How the class gradebook averages work

Student average = Σ (category% × weight) ÷ Σ weights
Class average = mean of student averages

Enter category results as percentages (for 45/50 homework, enter 90). Weights should total ~100%; otherwise averages use normalized weights and a warning appears.

Use teacher grader when you only need one test’s points→percent for the whole class. Use the gradebook calculator for a single student’s detailed assignment list.

FREQUENTLY ASKED QUESTIONS

Class Gradebook FAQ

How is this different from Teacher Grader and the home gradebook?

Teacher Grader scores one shared test for many students. The home page is a single-student weighted gradebook. Class Gradebook is a multi-student roster with several weighted categories—your differentiator for whole-class category grading.

Do student scores leave my device?

No. Calculations and optional CSV export run locally in the browser. There is no upload server for roster data.

How are category weights applied?

Each student’s average = Σ (category % × category weight / Σ weights). Keep weights near 100%. If they drift, the tool normalizes and warns you.

Can I export a CSV?

Yes. Export downloads Name, each category, Average, and Letter. Names that look like spreadsheet formulas are escaped.

Is this a free online gradebook for teachers?

It is a lightweight local class gradebook for planning and reporting averages—not a full LMS. For one test only, use Teacher Grader; for one student’s syllabus categories, use the home calculator.

How many students and categories can I add?

Up to 100 students and 8 weighted categories in this version. Keep exports under typical spreadsheet limits.
