How to Tell If Your Child Used AI for Homework

A sudden change in tone, polished grammar, unusual vocabulary or a detector result may prompt a conversation, but none proves by itself that a child used AI. Students may improve, receive editing help, use accessibility tools or write differently for different assignments. AI detectors also make mistakes. A 2023 Patterns study found high false positives for non-native English writers in one specific detector sample; it does not measure every current tool or population. Turnitin likewise says its AI writing model may misidentify text and should not be the sole basis for adverse action. Begin with curiosity rather than accusation. Ask the child to describe how they chose a topic, found sources, formed an argument and revised the draft. Invite them to show notes, outlines, earlier versions or sources, while remembering that not every student saves the same process artifacts. If the work is confusing or inconsistent, discuss the ideas: ask for an explanation of a key paragraph or invite the student to revise one section with you. Check the teacher’s instructions and school policy. Rules may differ by assignment and may allow brainstorming, grammar feedback or citation help while restricting generated prose. Clarify what tool use must be disclosed and how accommodations or language support fit the rules. If a detector or report is involved, request a fair process that considers the student’s explanation and other evidence before any consequence. Avoid uploading a child’s work to an unapproved third-party detector, especially if it contains personal information. The goal is to understand learning and set expectations, not to catch a child through unreliable signals. Agree on transparent boundaries: when AI can help, what must remain the student’s own work, and how to cite or disclose assistance. If there is a real concern, work with the teacher to support learning and apply policy consistently.
