How do I stop students cheating with AI?
Design tasks AI cannot complete for them: do key writing in class, assess drafts and planning, ask for personal or local details, and follow up with a short oral explanation. Set clear rules on when AI is allowed, teach why practice matters, and rely on knowing students' work rather than detectors.
You cannot stop AI misuse with detection alone, so the most effective approach is prevention: design work that shows a student's own thinking, set clear rules about when AI is allowed, and explain why doing the work matters. Students cheat less when the task makes the process visible and the expectations are plain.
Design tasks that show the thinking
| Instead of | Try |
|---|---|
| A finished essay written at home | A plan written in class, then a draft, then a final copy |
| "Write about the Romans" | "Write about what surprised you on our museum trip" |
| A worksheet with one right answer | "Show two ways to solve this and explain which is better" |
| A take-home book report | A two-minute talk, then three questions from the class |
| A research summary | Annotated notes with sources the student can show you |
Personal experience, class discussions, local details and hands-on work are hard to outsource. Short oral follow-ups ("Tell me how you got that") are quick and work at every age.
Set clear rules, by task
Children, especially younger ones, often do not know where the line is. Name it for each task:
- AI not allowed: tests, spelling and handwriting practice, independent writing, times-table practice.
- AI allowed with credit: brainstorming topics, checking understanding of a concept, getting an explanation another way.
- AI used by the teacher only: demonstrations on the board.
The UK's Joint Council for Qualifications requires students to acknowledge AI use in assessed work and treats undisclosed AI content as malpractice (JCQ guidance). A simple "how I used AI" line on assignments builds the same habit early.
Explain why it matters
Students are more likely to follow rules they understand. Research gives you a concrete story: in a 2025 study in PNAS, high school students who practised math with an answer-giving AI scored 17% lower than the control group once the AI was removed. Practice is how the brain learns, and skipping it has a cost. See Does using AI make students worse at thinking?.
Give students an honest way to get help
A lot of misuse starts with a stuck student at home. Offer alternatives: a homework club, worked examples, or a tool designed to explain rather than hand over answers. In the PNAS study, the version of the AI that gave hints instead of answers largely avoided the learning loss. Askie, for example, is designed to explain homework rather than simply give answers, and Askie for Schools lets teachers review students' conversation history.
When you suspect misuse
- Compare the work with the student's classwork.
- Ask them to explain it in a calm, private conversation.
- For young children, treat a first case as a misunderstanding of the rules.
- Follow your school's policy for repeat or assessed cases.
