Guardrails

Guardrails are rules and checks that limit what an AI will do, such as refusing certain requests, withholding final answers or pointing a student to help.

Why it matters for schools

Two lessons from the research. First, many guardrails are defaults rather than locks: students can leave consumer study modes, and teacher-configured bots followed intended rules 70.4% of the time. Second, guardrails stop harm but do not create gains on their own: a hint-first AI removed the harm of answer-giving AI but did not beat no AI. Structure and teachers create the gains.
