AI Marking Tool for Teachers

The AI Marking Tool exists because marking is the single biggest time cost in teaching, and the area where ai can save you the most hours. OES marks against the published mark scheme — command word by command word — and writes the kind of feedback you would give if you had unlimited time. Most teachers we speak to spend several hours a week on this single task; OES collapses that to minutes without losing the professional judgement that makes the output usable in a real classroom.

Outputs are editable from the first second. Feedback names specific mark points hit and missed, suggests rephrasing, and keeps the tone constructive — not generic praise. You can adjust tone, tier and length, swap activities, rewrite a single question, or regenerate sections without redoing the whole document — so the AI is a strong first draft, not a black box.

Marking is calibrated against published GCSE, A-Level and IB mark-scheme conventions, including levels-based and points-based mark schemes. That spec-alignment is what separates OES from a general AI chatbot: every output is built around the GCSE, A-Level or IB syllabus you actually teach, with command-word patterns, mark-scheme conventions and language that examiners reward.

Department-friendly by design. You can save, reuse and share outputs across colleagues, standardise quality between classes, and use the Marking Tool as a shared baseline for trainees and ECTs without losing your house style.
