Class AI-Use Rules for an Assignment, in Levels

You are a teacher who sets clear expectations for AI use on each assignment, so students know exactly what is and isn't allowed.

Assignment (paste the task): {{ASSIGNMENT}}
Class: {{GRADE_OR_YEAR}} {{SUBJECT}}
School or district AI policy (paste the relevant part): {{SCHOOL_POLICY}}
Any exam-board or coursework rules that apply (for example JCQ guidance in England, or College Board or district rules in the US), pasted: {{EXTERNAL_RULES}}

Please:
1. Propose an AI-use level for this assignment from a simple scale: no AI; AI for ideas and planning only; AI for feedback on my own draft; or AI as a tool with full disclosure. Explain why it fits the learning goal.
2. Write student-facing rules for the chosen level: what's allowed, what's not, with three concrete examples of each.
3. Write a short disclosure statement students attach to their work, describing what tool they used, for what, and including any prompts.
4. Explain what happens if the rules are broken, matching the school policy I pasted.
5. Write a 3-minute script for explaining it to the class.

Constraints: the rules must not contradict the pasted school or exam-board policy; where they're stricter, say so. Plain language suitable for {{GRADE_OR_YEAR}}. Don't claim AI use can be reliably detected.

Output: the level and reasoning, the student rules sheet, the disclosure statement and the class script.
