Test Grader FAQ
What is an online test grader?
An online test grader is software that automatically scores tests and exams using AI. It handles multiple choice, short answer, and essay questions—returning grades and feedback in minutes rather than hours.
Can the test grader handle different question types?
Yes. GradeLab grades multiple choice, short answer, fill-in-the-blank, and essay questions. Mixed-format tests are fully supported—the same rubric-based AI evaluates objective and open-ended answers in a single session.
How fast can I grade a 100-student test?
A 100-student test can be graded in approximately 5 minutes once submissions are uploaded. You can then review AI scores and override any result before releasing grades to students.
Does the test grader work with bubble sheets or scantron-style tests?
Yes. You can upload scanned bubble sheets and the system reads each answer circle using computer vision, scores against your answer key, and returns a per-student result instantly—no dedicated hardware required.
Does it work with handwritten test answers?
Yes. GradeLab includes OCR trained on diverse handwriting styles. Upload scans or smartphone photos of handwritten answer sheets and the AI converts them to text, then applies your rubric for grading.
How does the AI handle partial credit?
You set the partial credit rules in your rubric—for example, 1 point for a partially correct answer and 2 for a fully correct one. The AI applies those rules consistently across every student submission.
Can I sync grades to my LMS?
Yes. Push grades and feedback directly to Canvas, Moodle, Google Classroom, or your SIS via our LMS integration and REST API. No manual export or copy-paste required.
Can I build a reusable question bank from my tests?
Yes. Every question you create or upload is saved to your question bank. You can tag questions by topic and difficulty, then pull from the bank to build future tests in minutes.
