Is my kid too dependent on AI for homework?
The data moved fast. Here's what parents are actually up against, and what's worth doing about it.
A 2026 RAND report found 62 percent of middle school, high school, and college students now use AI for homework, up from 48 percent just seven months earlier. That's not a slow trend. That's most students, and it's climbing month to month. If your kid is one of them, they're not an outlier. They're the norm.
The more interesting number from that same report: 67 percent of those students already believe their AI use is hurting their critical thinking. They're not confused about the tradeoff. They're making it anyway, which tells you this isn't primarily an awareness problem. It's a habit and incentive problem, and awareness alone won't fix it.
What the research says about the actual cost
A preregistered study out of FGV and UFRJ measured retention 45 days after a learning task and found an 11 percentage point gap between students who used AI assistance and those who didn't. That gap shows up specifically on the material the AI helped with, not across the board, which is a useful detail: it suggests the cost is concentrated exactly where the shortcut was taken.
Signs it's gone from tool to crutch
- They can't explain, out loud, how they got an answer they turned in.
- Grades on AI-assisted homework look fine, but test scores on the same material, done without AI, don't match.
- They reach for AI before attempting a problem, not after getting stuck on it.
- They've stopped asking you or a teacher for help and go straight to a chatbot instead, even for things you could explain in two minutes.
What tends to actually work
Banning AI outright is hard to enforce and often backfires, kids find workarounds and lose the chance to learn to use it well, which they'll need eventually anyway. A few things parents and teachers have found more workable:
- Separate "check my answer" from "give me the answer." The first preserves the attempt. The second replaces it.
- Ask for the explanation, not just the output. If they can walk you through their reasoning without the AI open, the learning likely happened. If they can't, it probably didn't.
- Watch the gap between assisted and unassisted performance. A quiz or in-class test is a decent natural check on whether homework help is translating into actual understanding.
- Talk about the tradeoff directly, using the actual numbers. Most students already sense something's off, per that RAND data. Naming it plainly, rather than lecturing, tends to land better than a blanket rule.

Frequently asked questions
Should schools just ban AI tools?
Most education researchers argue against blanket bans, since they're hard to enforce and don't teach the discernment students will need later. Structured, disclosed use tends to work better than prohibition.
At what age does this matter most?
The retention research suggests the cost is highest wherever the material is meant to build a durable skill, like foundational math or writing, which makes younger grades a more sensitive period than, say, a one-off high school elective.
