Assess learners' ability to apply plain-language principles and interpret readability formulas (e.g., Flesch‑Kincaid, SMOG, Gunning Fog) to revise professional documents—memos, reports, policies, and emails—so edits improve clarity, concision, organization, and target reading level while preserving accuracy and required terminology; tasks include calculating/reading scores, identifying problems (word choice, sentence length, passive voice, structure), proposing concrete revisions, and explaining trade‑offs.
