What exactly is an
AI Marking Tool?
A class set of essays takes hours. Every teacher knows the trade-off: write proper feedback for everyone, or get the marks back to students this week.
An AI marking tool reads each submission, applies your mark scheme, and drafts a mark plus per-criterion feedback. You review, adjust, and sign off before anything reaches a student. CoGrader works this way by default.

How AI Marking Works with CoGrader
Three steps. Upload student work, then send marked essays back to the class.
Import from your VLE
Connect Google Classroom, Canvas, or Schoology. CoGrader pulls in the assignment prompt and every submission.

Pick a preloaded rubric for GCSE, A-Level, Cambridge IGCSE, IB, NCEA, or the Australian Curriculum. Or upload your own.
Review marks and feedback
CoGrader drafts marks and feedback per student. You read each one, adjust where you disagree, and push results back to your VLE.
What Teachers Need to Know About AI Marking
An AI marking tool applies your mark scheme to every submission and drafts feedback in minutes. You review and approve before students see anything.
CoGrader supports the mark schemes teachers in the UK, Australia, and New Zealand actually use: GCSE and A-Level rubrics from AQA, OCR, and Edexcel, Cambridge IGCSE criteria, NCEA Achievement Standards, and Australian state curricula (HSC, VCE, QCE, WACE). You can also upload any custom mark scheme from your school or department.
Feedback ties to specific rubric criteria, so each student sees what they scored per criterion and where to focus next time. Teachers who use CoGrader tell us they assign more writing once the marking bottleneck is gone.
US teacher? CoGrader works the same way for state standards and AP rubrics. See CoGrader for AI grading for the US-equivalent overview.
The Evidence Behind AI Marking
What UK regulators and independent research say about teacher-supervised AI marking.
AI marking is now a regulated topic in the UK. The Department for Education's principles of AI use in marking set three tests for any tool used on student work: technical capability, fairness, and transparency. Teachers should see how a mark was reached. Systems should be audited for bias. The human marker stays responsible for the final decision.
Independent research points the same way. A 2025 arXiv paper, CoGrader, studies AI-assisted grading at scale: rubric-bound AI marking holds up well on structured assessments paired with teacher review, while extended creative writing is where teacher judgement still matters most.
How CoGrader meets these standards
Fairness
CoGrader applies your mark scheme the same way on essay 1 and essay 30. The drift that creeps in when you've been marking for three hours doesn't.
Transparency
Each mark links to the rubric criterion that earned it, with the explanation in plain language. When a parent or student asks why, you have the answer in front of you.
Teacher in the loop
CoGrader drafts the marks and feedback. You read each one, edit what you'd say differently, and approve before students see anything.
Why Teachers Choose CoGrader for AI Marking
One platform for marks and per-student feedback against your own rubric.
Marks + Personalised Feedback
CoGrader applies your mark scheme and writes personalised feedback per criterion for every student in the same pass. The marks and the feedback come together.
A Class Set in One Sitting
Upload thirty essays at once and CoGrader marks every paper against the same rubric in parallel. A class set that used to fill a Sunday afternoon comes back in around twenty minutes.
Imports Straight From Your VLE
Pull a whole class from Google Classroom, Canvas, or Schoology in one click. CoGrader marks the set and pushes marks and per-criterion feedback back where they came from.
