You just gave a test. Now what?
The test is done. The students have handed in their papers. And now you have 80 of them to grade before tomorrow morning.
The test has three parts. Multiple choice, which is easy but tedious. Twenty questions, eighty papers, that is sixteen hundred answers to check against an answer key. Short answers, which need your judgement because students phrase things differently. And one essay, which needs thoughtful, specific feedback if it is going to help anyone improve.
You start with the MCQ. It is simple work, but it eats your evening. By the time you get to the short answers, you are already tired. By the time you reach the essays, you are writing shorter comments because you simply do not have the energy to give 80 students the feedback they deserve.
What if the MCQ and short answer parts could be graded automatically, so you could spend your time on the essays? That is what GradeLab does. It grades the full test. Objective questions are graded instantly. Short answers are scored against your rubric. Essays are evaluated with your custom instructions. You review every mark, edit any feedback, and approve before results reach students.
What Is AI Test Grading?
AI test grading is software that reads your students' test papers, applies the answer key or rubric you already use, and suggests a mark for each question. It handles the reading, the checking, and the adding up. You review every suggestion, override anything you disagree with, and approve the results before they reach students.
GradeLab lets you add your own custom instructions so the AI grades the way you would. Tell it to award partial credit for a correct method even if the final answer is wrong. Tell it to accept two different approaches for the same question. Tell it to be strict about units in physics. The AI follows your instructions on every paper, consistently, whether it is paper 1 at 2 PM or paper 80 at midnight.
The repetitive part of test grading, the part a machine can do, gets automated. The judgement part, the part that needs a teacher, stays with you.

AI Test Grading That Handles the Full Paper
GradeLab grades every question type on your test, from multiple choice to essays, with your rubric and custom instructions applied consistently on every paper.
Instant Objective Question Grading
Multiple choice, true or false, and fill in the blank questions are graded instantly against your answer key. No manual checking, no tallying, no errors from counting by hand at midnight.
Short Answer Grading with Your Rubric
Short answers are scored against the rubric you define. The AI reads each response, checks for the key concepts you specified, and suggests a mark with visible reasoning. You review and approve.
Essay Grading with Custom Instructions
Essays are evaluated for argument, evidence, structure, and voice, against your criteria. Add instructions like "give credit for original argument even if I disagree with the conclusion" and the AI follows that rule on every essay.
Reads Handwritten Answer Sheets
Upload scanned papers or phone photos. GradeLab reads the handwriting with OCR, maps each answer to the correct question, and prepares every response for grading. No special scanners required.
Bubble Sheet and Scantron Support
Upload scanned bubble sheets and GradeLab reads each answer circle using computer vision, scores against your answer key, and returns a per student result instantly. No dedicated hardware required.
Partial Credit and Step Marks
You set the partial credit rules in your rubric. GradeLab evaluates each step, awards credit for correct method, and only deducts where a specific step actually fails. Consistent on every paper.
Automatic Totals and Grade Export
No more adding up marks by hand or typing totals into a spreadsheet. GradeLab calculates the total for every paper and lets you export the full grade sheet in one click, or sync to your LMS.
Feedback for Every Student
Every student gets specific feedback on where they lost marks and what to study next, not just a number. You can edit the feedback before it goes out, so it sounds like you wrote it.
You Override Anything
GradeLab suggests. You decide. Override any mark, rewrite any feedback comment, add your own notes. Nothing reaches a student until you have approved it. The AI is your assistant, not your replacement.

AI Test Grading FAQ
What is AI test grading?
AI test grading is what happens when the repetitive parts of grading a test are handled by software. GradeLab reads the student responses, applies your rubric or answer key, suggests marks for each question, and writes feedback. You review the suggestions, override anything you disagree with, and approve. It works for MCQ, short answers, essays, and mixed-format tests.
Can AI grade multiple choice questions automatically?
Yes. MCQ scoring is instant. Upload your answer key and GradeLab scores every objective question immediately. For short answers and essays, the AI applies your rubric with your custom instructions and suggests marks for your review.
Can I add custom instructions for test grading?
Yes. You write your rules in plain English and GradeLab follows them on every paper. For example: "accept both A and C for question 7 because both are valid" or "award partial credit for showing working even if the answer is wrong." The AI applies your rules consistently on every test.
How fast is AI test grading?
A class of 80 tests comes back with suggested marks in under 5 minutes. You then review flagged answers, check anything you want, and approve. Most teachers finish the full review in 10 to 15 minutes instead of spending hours grading by hand.
Does AI test grading work for handwritten tests?
Yes. Upload scanned papers or phone photos. GradeLab reads the handwriting using OCR, maps each answer to the correct question, and suggests marks. You review and approve before results go out.
Can I see which questions the whole class struggled with?
Yes. GradeLab shows you question-level analytics: which questions were missed most often, which topics need reteaching, and which students need extra help. This helps you adjust your teaching based on real data, not guesswork.

Thomas Braun
Lecturer, Pure Mathematics, Germany
My students write formal mathematical proofs. On a convergence proof question, GradeLab correctly identified whether the quantifier structure was right, whether the chosen bound worked, and where the logical chain broke. It did not just check the final line. That is the part that matters.
Dr. Isabelle Fontaine
Associate Professor, Theoretical Physics, France
GradeLab evaluated a wavefunction normalisation problem across 140 papers and correctly flagged eleven cases where students had a correct final integral but had used the wrong boundary condition. That is precise, subject-aware marking.
Prof. James Fletcher
Mechanical Engineering, Thermodynamics, USA
GradeLab evaluated a question on entropy generation in a throttling process and correctly identified which students had omitted the system definition, which had applied the steady-flow energy equation incorrectly, and which had confused entropy change with entropy generation. That distinction matters in this subject and it caught it reliably.

Sophie Laurent
Science Teacher, Lycée Henri IV, Paris
Before GradeLab, I spent every Sunday grading papers instead of being with my family. Now I upload the batch on Friday evening and by Saturday morning, every student has already seen their feedback. That part still surprises me.
Maria Santos
Teacher, Escola Internacional de Lisboa
I teach four classes with 35 students each. I genuinely could not keep up with grading. GradeLab didn't just save me time - it gave me back the ability to actually know where each student was struggling.
Sarah Mitchell
Head of Academics, Wellington Grammar School
We trialled several edtech platforms before GradeLab. What stood out was that it wasn't just grading software - the student feedback loop was instant, and the quality reports for governors were exactly what we needed.
