Tired of audit ping‑pong over what counts as “acceptable evidence”? This lesson gives you a precise, reusable template and model phrasing to define evidence acceptance criteria that auditors can test and teams can reproduce—on time, with zero ambiguity. You’ll get a clear framework, concrete examples across five control families, and practical do/don’t guidance, plus short exercises to confirm you can write criteria that stand up. Finish with audit‑grade language, measurable thresholds, and operational steps that cut rework and move audits forward.
