GUARD Focused Lab · Student Card
Human Override Challenge
Do not let an AI flag become an unreviewed accusation.
GUARD focus: D / R · 12–15 minutes · Classes 9–10
Situation
A school writing checker gives a student's essay a 91% 'AI-generated' score. The teacher notices that the student's style changed from earlier work. The checker provides no source match or sentence-level explanation. The student says they used accessibility support and has notes and earlier drafts.
Learning objective
Identify consequential decision points requiring accountable human review, evidence, explanation and appeal.
1. Choose the immediate action
What should happen first?
- Issue the penalty immediately because 91% is above 90%.
- Pause the accusation, review the work and process, and give the student a fair opportunity to explain and provide drafts.
- Ignore the flag completely because AI detectors are never useful.
Reasoning:
2. Choose the evidence for review
Which evidence should the human reviewer consider?
- □ The student's notes, drafts, revision history and ability to explain the argument.
- □ The assignment rules and what AI or accessibility support was permitted.
- □ The checker's documented limitations, validation evidence and error rates for comparable students and tasks.
- □ Relevant accessibility or language-support context, handled confidentially.
- □ Only the 91% score, because additional evidence could confuse the decision.
- □ Whether classmates think the student probably used AI.
Reasoning:
3. Assign accountable roles
Which people or roles should be part of a fair process?
- □ The teacher, who understands the assignment and student work.
- □ The student, with a chance to explain and provide evidence.
- □ An appropriate academic or school lead for serious or disputed findings.
- □ A relevant accessibility or safeguarding professional where necessary and authorised.
- □ The detector itself as the final accountable decision-maker.
Reasoning:
4. Design the appeal route
What appeal mechanism is strongest?
- Allow an appeal only if the student can prove the detector is technically defective.
- Explain the concern and evidence, allow the student to respond, and provide review by an appropriate human who can change the decision.
- Let the same automatic checker run the essay again and call the second score an appeal.
