Test learners' ability to apply plain‑language principles to revise workplace policies, reports, and professional communications. Assess skills in identifying and removing jargon, converting passive to active voice, shortening and restructuring sentences for clarity, using headings/lists for scannability, tailoring tone to specific audiences while preserving legal/technical accuracy, and justifying revisions. Include multiple-choice principle checks, short edits, and before/after rewrite tasks using HR, safety, and client‑facing scenarios.
