AI Marking Software and Your School Directed Time Budget

Every July, senior leaders sit down with the following year's calendar and try to make the sums work. When you plan a school's directed time budget — the 1,265 hours set out in the School Teachers' Pay and Conditions Document — you allocate INSET, meetings, parents' evenings, duties and cover with some care. Marking, though, is the elephant in the spreadsheet: it is core to the job, it is time-consuming, and yet most of it happens outside directed time altogether, at kitchen tables on Sunday nights. This guide is for leaders who want the marking load to actually fit the time available, and looks at where AI marking software fits into that planning.

GradeOrbit is an AI-powered marking assistant for UK teachers. It does not replace professional judgment — teachers stay the marker and confirm every grade — but it removes the slow, mechanical first pass, which is precisely the part of marking that inflates the hidden workload directed time never captures.

Why Marking Never Fits the Budget

Directed time is a finite pot, and marking has a habit of expanding beyond it. The Department for Education's own workload research has repeatedly identified marking as one of the largest single drivers of teacher hours, and much of that time is invisible to any timetable because it is done at home. A leader can allocate directed time for meetings and CPD down to the hour, but the marking a full teaching load generates simply does not shrink to fit — it overflows into evenings and weekends, and it is a leading reason teachers give for leaving.

That overflow is the real workload problem. When leaders talk about protecting staff wellbeing or improving retention, the honest question is not "how do we direct more time to marking?" but "how do we reduce the marking hours a teacher has to find in the first place?" Our guide on where teacher marking time actually goes breaks down exactly where those hours accumulate.

Making Marking Visible in the Plan

The first move is to stop treating marking as a residual. In directed time planning, name it: estimate the marking each key assessment point generates across departments, and treat that estimate as a real demand on staff time rather than something that happens by magic after the bell. Once marking is visible in the plan, the case for reducing it becomes concrete rather than aspirational.

This is where AI marking software changes the arithmetic. If the first read of a class set — the transcription, the checking against the scheme, the drafting of feedback — is done by a tool the teacher then reviews and confirms, the hours a given assessment demands fall substantially. The learning value of marking is preserved, because the teacher still makes every judgment, but the mechanical labour that never fit the budget is largely removed. Our piece on using AI marking software to protect teacher time looks at this from the leadership angle.

What GradeOrbit Actually Does

GradeOrbit is built for the reality of secondary marking, including physical paper. Teachers scan handwritten scripts — capturing them straight from a phone camera via an on-screen QR code — and the tool reads the work, marks it against criteria the teacher defines (exam board, specification, mark scheme), and proposes a grade with transcription and feedback for the teacher to review, adjust and confirm.

Crucially, it handles both families of mark scheme equally: the levels-based, descriptor-driven essays of English, history and sociology, and the marks-based, method-mark schemes of maths, the sciences and geography, where working-out and calculation steps carry the credit. That breadth matters for a directed time plan, because it means the workload saving reaches across the whole school, not just the essay subjects.

A Fair, Consistent Read Across the School

There is a quality-assurance dividend as well as a time one. Because GradeOrbit marks every script against the same defined criteria, the first pass is consistent in a way tired human marking cannot always be at the end of a long pile. That consistency supports moderation and standardisation, and it makes the marks more defensible when a department reviews its work. For leaders thinking about how this sits alongside existing workload commitments, our guide on AI marking software and the DfE workload reduction toolkit connects it to national guidance, and how to reduce teacher workload across your school covers the broader rollout.

Data Protection and the Institutional View

Leaders rightly ask about data before rolling anything out. GradeOrbit offers a school journey designed for institutional use under a data processing agreement, so a trust or school can adopt it with the governance a directed time and workload strategy needs behind it. Marking is treated as the serious, assessment-critical activity it is, not a bolt-on.

Try GradeOrbit for Your School

If your directed time budget never quite contains the marking it should, the answer is to shrink the marking hours, not to squeeze more time from staff who have none to give. GradeOrbit does the first, exhausting read so your teachers spend their time confirming judgments and giving feedback — the part that actually helps students — inside the time they have. It is assistive by design: your staff stay the markers, and every grade is still theirs to award.
