Grading & rubrics

Grade work against your own criteria.

Build a rubric for any activity, and grade each part by hand, with AI, or with code tests.

What does it do?

Grade with a rubric, the way you already do. Score each part by hand, with AI, or with code tests, and review it all in one place.

Who is it for?

Teachers and teaching assistants

Grade every submission against the same clear criteria.

CS instructors

Combine automatic code tests with your own judgment.

Features

AI grading criteria

Write what you’re looking for and describe each score level. The AI grades against your descriptions, and you can review every score.

Code tests

For coding work, each test runs the program with your input and checks the output. Add a test for each case you care about.

Manual grading

Grade by hand when the work needs your judgment.

Questions

Can I mix grading methods?

Yes, where the activity supports it. A coding exercise, for example, can combine automatic tests with items you grade yourself.

What do I provide for AI grading?

Describe what you’re looking for and what each score level means. The clearer your descriptions, the more consistent the grading.

Which plans include AI grading?

Every plan, including free Starter. Starter courses get fewer AI credits, so for a whole class over a term, Core or Pro is a better fit.
