Is my teen cheating with AI? How to tell learning from shortcuts
Short answer
It depends on two things: the rules for that piece of work, and who did the thinking. If the rules for that task say no AI, it's cheating, even if your teen understood the work. If AI was allowed and your teen can explain the work without the screen, the AI was a tool. If they can't explain what they handed in, the AI did the learning for them.
How common is it?
In a Common Sense Media survey of more than 1,000 US teens, 7 in 10 said they use AI for schoolwork. Among them, about 6 in 10 had used it to get an answer directly, and more than 3 in 4 had used it without asking for the answer. (Common Sense Media, August 2026)
Teens see it around them too. In a Pew Research Center survey of US teens aged 13 to 17, 59% said using AI to cheat happens at least somewhat often at their school. (Pew Research Center, February 2026)
Parents are stricter than teens. In a Common Sense Media survey of 1,244 parents, 52% said it is not ethical to rely on AI to complete school assignments. (Education Week, March 2026)
Start with the rules for that task
Rules change by school, by teacher and by assignment: brainstorming with AI may be fine where writing the answer is not. Ask your teen what each teacher allows, and read the school's policy if there is one. When the rule is unclear, the safe default is to ask the teacher before using AI, not after.
Five questions that show who did the thinking
Common Sense Media puts the core test in one line: "Can they explain the work themselves?" These questions turn it into a five-minute conversation, with no accusation in it:
- "Walk me through how you got to this answer."
- "What did the AI suggest that you didn't use, and why?"
- "Which part was hardest?"
- "What would you change if you did it again?"
- "Explain it to me as if I had never seen it, without the screen."
If your teen did the thinking, these are easy to answer, even with AI help. If they stall early, ask the teacher what was allowed for that task.
Practice on a project of their own
Schoolwork has grades and rules, which makes it a stressful place to learn how to work with AI. A project of their own, like a study app or a small game, is a lower-stakes place to practice the same habits in the open: picking what to build, asking the AI for small changes and checking each result.
At the end, a short note on who did what makes the thinking visible to you and to them:
A project of their own is where your teen can use AI openly and still own the result.
