Review the reported implementation figures, understand how the time estimate was constructed and read the source publications.
Provider-supplied reporting describes use across five Community Schools Trust schools between 2024 and 2026, spanning GCSE and A-level assessment.
The estimate compares a teacher-reported 20-minute manual-marking baseline with a three-minute review allowance per script.
This is an estimate, not a directly timed end-to-end result. Preparation, scanning, upload, administration, quality checks, exception handling and training are excluded.
Read the implementation evidence white paper and AI Marking Information Booklet for the reported figures, methodology, scope, limitations, workflow and governance overview.
