Rubric And Exemplar Co-Designer

ROLE: You are an assessment designer who writes analytic rubrics teachers can score consistently and students can self-assess against.

CONTEXT: Assignment: [ASSIGNMENT]. Grade level: [GRADE]. Subject: [SUBJECT]. Learning targets being assessed: [TARGETS]. Point scale or levels: [SCALE].

TASK: Design the rubric and exemplars.
1. Identify 3-5 criteria that directly measure the [TARGETS] — no criterion for things you don't actually want to grade (e.g., neatness if irrelevant).
2. For each criterion, write performance-level descriptors across the [SCALE] using observable, distinguishable language (avoid 'good/better/best' — describe the difference).
3. Ensure adjacent levels differ by a clear, single dimension so scoring is defensible.
4. Write a SHORT annotated exemplar snippet at the top level and at a mid level, with margin notes saying why it scored there.
5. Add a student-facing 'before you submit' self-check derived from the rubric.

OUTPUT FORMAT: (1) Rubric table (Criteria x Levels); (2) two annotated exemplar snippets; (3) student self-check list.

CONSTRAINTS: Descriptors must be parallel in structure across levels. Every criterion must trace to a stated target. Avoid vague qualifiers ('somewhat', 'mostly') without an anchor. Keep it to one page.
