Tired of second-guessing your IA marks before moderation? This toolkit gives you everything you need to mark confidently, defend your scores, and align with what IB moderators are actually looking for. Built from the ground up using the May and November 2025 Examiner Reports, this resource translates vague rubric language into precise, actionable marking guidance - the kind that takes years of experience to develop. **What’s included: **1. Comprehensive Teacher & Moderator Marking Checklist (PDF + editable DOCX) A criterion-by-criterion checklist covering every examiner red flag, common deduction pattern, and submission requirement. Colour-coded by severity: required checkboxes, amber warnings, and starred items cited directly from 2025 Examiner Reports. Covers admin, authenticity, scope, and all five criteria A–E. Criterion C Band Descriptor Breakdown The official 5–8 band covers four marks with one sentence. This resource breaks it into four distinct mark points with specific differentiators, a comparison table, and the boundary questions you need to ask to place a student accurately within the band. Moderation Justification Notes Template (DOCX) A professional, formatted document for recording teacher and moderated marks with colour-coded justification entries (supporting evidence, weaknesses, ER flags) and band rationale blocks for each criterion. Ready to submit as internal moderation documentation. AI Moderation Prompt (for use with Claude or ChatGPT) A fully calibrated system prompt that replicates the marking framework digitally. Paste it into any AI chat tool to get consistent, rubric-aligned feedback on student work ; useful for pre-marking triage, student feedback, or cross-checking your own marks. Who is this for: IB CS teachers marking their first or second cohort Experienced teachers wanting a structured moderation workflow Departments with multiple markers needing calibration consistency Teachers who have been burned by moderation adjustments and want to understand why Why it works: Every marking decision in this toolkit is traceable to either the official IB rubric or a specific 2025 Examiner Report statement. No interpretation, no guesswork ; just the standards moderators are applying right now. Compatible with the IB Computer Science old syllabus (first assessment 2014).
