Assessments & Feedback · Free for teachers

Grading that hands the work back, not just the score

Write and grade assessments with AI, against rubrics you approve, and nothing reaches a student until you release it. When grades go out, students who missed points can explain their mistake or solve a similar question and earn some of those points back.

Turn feedback into the next step.

From first question to final feedback

Four stages, and you hold the gate at every one of them.

1

Author or generate

Write questions yourself, or generate them from your course framework. Every generated item goes through a verification pass that tries to refute its own answer key before you ever see it. Items you approve land in your bank with their provenance attached.

2

Deliver

Students take the test in a runner modeled on the digital AP exam: question navigator, cross-outs, highlights, a review screen before submitting. The timer lives on the server. Answer keys never reach the browser.

3

Grade

Multiple choice scores itself. Free response is graded point by point against the rubric, with a written rationale for every point awarded or withheld. A class set comes back in minutes, not a weekend.

4

Review and release

Grades wait in a review queue until you release them. Skim, adjust, override. The release button is yours, and it stays yours.

Students earn their marks back

A returned test becomes a second attempt, with corrections that you review.

Question 4 · cellular respiration FRQ

3 / 7

Path one: explain what went wrong and reason through the correct answer.

Path two: solve a fresh question on the same topic, at the same difficulty, generated for this correction.

3 / 7 → 6 / 7 credit restored on the original question

Corrections are graded provisionally by AI and land on your desk. Nothing is restored until you sign off.

You have the last word

  • The review gate is on by default. Turning it off is your choice per assessment, never the system's.
  • Scores are never overwritten. Every regrade is a new record with its source attached, so a grade's history is always readable.
  • Students can flag a grade, with an explanation required. A flag triggers a clean-context AI second read that arrives as advice on your desk, not as a changed grade.
  • Timing and focus signals are visible to you and hidden during grading. They are never an input to a score.

Designed for classrooms where a teacher reviews the work and makes the final call.

Where it stands

Built and piloted in AP Environmental Science. The full pipeline works end to end: authoring and generation, the Bluebook-style runner, AI and self grading, review and release, flags and regrades, corrections, item analytics. Accessibility has had a real pass, with text scaling, high contrast, and screen-reader work verified against WCAG.

Assessments & Feedback works standalone. If your school already runs a lockdown tool, it stays out of its way. For supervised browser activities, Supervised Class Sessions is a separate Chrome extension with attention signals and a session report. Assessments can also use the extension for extra checks; what monitoring can and can’t do lists the limits of each option.
