Written Communication
What this domain tests
Written communication items assess whether you can produce clear, correct, and appropriately toned workplace writing: incident reports, log entries, emails, and short memos. Questions may ask you to choose the best sentence, spot the error in a sentence, select the most professional phrasing, or identify the clearest revision of a passage.
Concepts to master
- Sentence completeness: every sentence needs a subject and a verb; avoid fragments and run-ons.
- Subject-verb agreement: the verb matches the true subject, not a phrase between them (The list of supplies is...).
- Pronoun clarity: each pronoun must have one obvious antecedent; avoid vague this or it.
- Parallel structure: items in a list share grammatical form.
- Conciseness: cut redundancy (advance planning, returned back).
- Tone and register: professional, neutral, factual; no slang, no blame, no editorializing.
- Punctuation basics: commas in lists and after introductory phrases; apostrophes for possession.
Traps to expect
- Sentences that sound impressive but are wordy or vague.
- Agreement errors hidden behind interrupting phrases.
- Overly casual or accusatory wording that is technically grammatical.
- Punctuation that changes meaning (comma splices).
Worked example / rule of thumb
Choose the best version: (A) 'The crew was dispatched, they arrived quickly.' (B) 'The crew was dispatched and arrived quickly.' (C) 'The crew, being dispatched, arrived quickly.' Answer: B. A is a comma splice; C is wordy and awkward. Rule of thumb: prefer the shortest version that is complete, clear, and professional, and read it aloud to catch fragments and run-ons.
