What this skill is asking
Editing fixes grammar and usage errors, and STAAR English I tests it with multiple-choice questions on a student draft, plus the same conventions are scored on the ECR's Use of Conventions trait. The errors STAAR tests recur: subject-verb agreement, pronoun-antecedent agreement and pronoun case, verb-tense consistency, and misplaced or dangling modifiers. The skill is recognizing these specific error types and knowing the correct form. This page covers each error type, its common trap, and how to fix it. The transferable skill is reading a sentence against the grammar rules these questions test, and carrying that habit into proofreading your own writing.
Agreement errors: subject-verb and pronoun-antecedent
Agreement is the most-tested usage area, and the traps are predictable.
For both, the fix begins by finding the real subject or antecedent. Strip away the modifying phrases and ask, "what is this verb actually about?" or "what noun does this pronoun replace?" Then match for number. Most agreement questions resolve once the true subject or antecedent is identified.
Pronoun case, verb tense, and modifiers
Three more error types complete the set.
These error types are testable because each has an unambiguous rule. A modifier must attach to the right word; tenses must stay consistent; case must fit the pronoun's role. When an editing question offers several versions of a sentence, the correct one is the one that satisfies the relevant rule, and the distractors each break it in a recognizable way.
Editing under time pressure
Try this
Q1. In "The list of supplies (was/were) on the desk," which verb is correct and why? [Recall]
- Cue. "Was." The subject is "list" (singular), not "supplies"; the phrase "of supplies" is a modifier. Subject-verb agreement matches the verb to the true subject, so the singular "was" is correct.
Q2. Why is "Each student must bring their own pencil" a usage error, and how do you fix it? [Short explanation]
- Cue. "Each student" is singular, but "their" is plural, breaking pronoun-antecedent agreement. Fix it with a singular pronoun: "Each student must bring his or her own pencil" (or recast as "Students must bring their own pencils").

STAAR English I (editing, style)1 marksWhich sentence is correct? (1) The group of students were ready. (2) The group of students was ready. (3) The group of students is being ready. (4) The group of students are ready.Show worked answer →
Answer: (2). Subject-verb agreement: the subject is "group" (singular), not "students," so it takes a singular verb, "was." The phrase "of students" is a modifier, not the subject.
Why not the others: (1) and (4) wrongly make the verb plural to match "students"; (3) "is being ready" is not idiomatic. The trap is a prepositional phrase between the subject and verb; identify the true subject ("group") and match the verb to it.
STAAR English I (editing, style)1 marksWhich sentence corrects the pronoun error in 'Each of the players brought their own gear'? (1) Each of the players brought their own gear. (2) Each of the players brought his or her own gear. (3) Each of the players brought they own gear. (4) Each of the players brought our own gear.Show worked answer →
Answer: (2). Pronoun-antecedent agreement: "each" is singular, so the pronoun should be singular, "his or her." The original pairs singular "each" with plural "their."
Why not the others: (1) repeats the error; (3) "they own" is ungrammatical; (4) "our" does not match "each of the players." STAAR usage questions test agreement between a pronoun and its antecedent; a singular antecedent ("each") needs a singular pronoun.
