Writing: Written Expression and Conventions of Standard English

What the domain tests

The Writing domain has two faces. Written expression asks you to choose the best revision: a clearer thesis, a logical order, a transition, a more precise word, or a sentence that combines ideas without losing meaning. Conventions asks you to edit: grammar, usage, punctuation, capitalization, and spelling, tied to NYS Next Generation Language Standards 1–2. The exam favors meaning-preserving edits; the right answer must fix the problem without changing the writer's intent.

Core rules

  • Revision first, editing second. Ask what the sentence is trying to do before hunting for a comma error.
  • A strong response has a controlling idea, organized paragraphs, and transitions that show relationships (however, therefore, for example).
  • Keep text type in mind: argument needs claim, reasons, evidence, counterclaim; informative/explanatory needs a clear topic and accurate details; narrative needs consistent point of view and pacing.
  • For conventions, check subject–verb agreement, pronoun–antecedent agreement, verb tense consistency, parallel structure, and modifier placement.
  • Punctuation: use commas for introductory elements, items in a series, and nonrestrictive clauses; use a semicolon between related independent clauses; use a colon after a complete sentence to introduce a list or explanation.
  • Avoid comma splices and run-ons; join independent clauses with a period, semicolon, or comma plus coordinating conjunction.

Worked example

Sentence: "The student who won the essay contest, they were awarded a scholarship." Problem: the subject "student" is repeated by "they," creating a pronoun error and an awkward interruption. Revision: "The student who won the essay contest was awarded a scholarship." Reasoning: remove the redundant pronoun; the relative clause "who won the essay contest" modifies "student," and the main verb "was awarded" agrees with the singular subject.

Traps

Choosing an edit that changes meaning; fixing one error while creating a comma splice; leaving a pronoun with an unclear antecedent; shifting tense mid-paragraph; confusing revision (ideas and organization) with editing (mechanics).
