Introduction
Pronoun-Antecedent Agreement falls under Standard English Conventions (SEC), which accounts for roughly 26% of operational Reading and Writing questions. Within SEC, this skill tests whether a pronoun correctly matches its antecedent — the noun it refers back to — in number (singular vs. plural) and person (first, second, or third). Questions give you an underlined pronoun or a blank and ask you to pick the form that follows conventional usage. Getting this right requires identifying the true antecedent before you touch the options.
Core Concept
A pronoun must agree with its antecedent in number and person. Sounds simple — but test writers deliberately obscure the antecedent using three main traps:
1. Singular collective nouns and organizations Nouns like committee, team, company, Congress, the university, and proper organization names (e.g., the firm, the agency) are grammatically singular in standard American English. They take its, not their.
The committee released its report. ✔ The committee released their report. ✗ (in standard written English)
2. Indefinite pronoun antecedents Indefinite pronouns such as each, every, either, neither, anyone, everyone, someone, nobody are singular. Their pronouns must be singular.
Each of the researchers submitted his or her data. ✔ Each of the researchers submitted their data. — acceptable in informal speech but marked wrong on the SAT when a singular alternative is available.
On the digital SAT, the test uses constructions where one option is clearly singular and the others are clearly wrong in some additional way, so the "singular vs. plural" distinction is always the deciding factor, not a stylistic preference.
3. Ambiguous this/these and it/they references A pronoun must have one clear antecedent. If this, these, it, or they could plausibly refer to more than one noun in the passage, the question will ask you to choose the option that is unambiguous — usually by replacing the vague pronoun with a noun phrase or by using a pronoun that only one antecedent matches.
Vague: The engineer reviewed the blueprint and the contract; it needed revision. Clear: The engineer reviewed the blueprint and the contract; the contract needed revision.
The SAT will present four options, typically varying between a pronoun and a descriptive noun phrase, and you must select whichever is grammatically and logically precise.
