How Teachers Handle AI Scores at Summer Deadline Crunch

By the back end of the summer term, the coursework comes in waves. Year 11 NEA submissions, sixth-form portfolios, the final drafts that have been promised for weeks. You are marking against a hard exam-board deadline, and somewhere in the stack a piece of work makes you pause. You run it through your AI detection tool, and a high likelihood score comes back. Now what?

This is the moment that matters for ai detection for teachers: not the score itself, but the decision you make after it. Under deadline pressure, the temptation is to react fast. The professional answer is to slow down by exactly the right amount, run a fair process, and keep your judgment at the centre of it.

Why Likelihood Scores Spike at Deadline Season

The end of the summer term concentrates every risk factor at once. Students who have left a major end of year coursework piece until the final week are tired, stressed, and tempted to cut corners. Drafts that were genuinely the student's own in March may have been "polished" with a generative tool in June. The volume of submissions landing in a 72-hour window means you are reading more work, more quickly, than at any other point in the year.

None of that means a high score is proof of anything. It means the conditions that produce both genuine AI use and false alarms are at their peak. A score is a signal to look more closely, not a verdict to act on.

Probabilistic, Not Proof: Reading the 0–100% Score

GradeOrbit returns a score from 0 to 100, and like any likelihood score it is an indicator, not proof. No detector on the market can prove a student used AI. GradeOrbit's score tells you how far the new piece departs from that pupil's own earlier writing on file - a low score means it is consistent with how they usually write, a high one means it differs in ways worth a closer look.

That has direct consequences for how you treat the number:

• A high score is a reason to investigate, never a reason to accuse.
• EAL students, very able students, and students who write in a flat, formulaic style can all produce naturally high-scoring work. This is not their fault and not your evidence.
• The score is one input into your professional judgment: alongside your knowledge of the student, their drafting history, and the work itself.

If you want the underlying mechanics, our guide on how AI detection likelihood scores work walks through what the percentage actually represents.

The Fair Process When You Have 40 Scripts and 3 Days

Deadline pressure is exactly when a clear process saves you. You do not have time to agonise over every borderline case, and you should not be inventing your approach script by script. Decide your steps once, then apply them consistently:

• Re-read the work yourself. Does the voice match earlier drafts and classwork? Does the argument show the messy thinking of a real student, or the suspiciously tidy fluency of generated text?
• Check the trail. Planning notes, earlier drafts, in-class writing - these are stronger evidence than any score.
• Talk to the student, don't ambush them. Ask them to explain their argument or expand a section. A student who wrote it can talk about it; this conversation protects everyone.
• Align with your school's policy. A high score should feed into an existing academic integrity policy, not a snap decision made alone at 11pm.

For the difficult conversations, our piece on what to do when a student denies using AI covers how to keep the discussion fair and evidence-led.

How GradeOrbit's Built-In Detection Fits Summer Marking

AI detection is part of GradeOrbit's school accounts, included in every teacher seat with no per-check charge, so you are not juggling a separate tool or rationing checks during the busiest weeks of the year. You can run it on one pupil from their profile or on a whole class at once, and for a class set you bulk upload the scans and GradeOrbit matches each cover page to the class list. It compares each submission against that pupil's own earlier work already on file, which is a stronger signal than a generic score for a piece heading into a reported grade. A pupil with no earlier work on file is skipped rather than given a guess.

Critically for end of year coursework: pupils' work is held under the school's signed Data Processing Agreement, scans are removed when a run archives, and pupil records follow the school's retention window and are wiped at offboarding - no open-ended record of a child's writing sitting on a server, and nothing used to train AI models. That privacy contract matters most precisely when you are handling sensitive coursework at scale.
