- The Core Rule: Singular subjects take singular verbs. Plural subjects take plural verbs.
- The SAT Trap: The test places distracting words and phrases (especially prepositional phrases) between the subject and the verb.
- The Solution: Identify and mentally cross out the phrases between the subject and the verb to see the true connection.
- Singular Verbs: Often end in "-s" in the present tense (for example, he runs, she talks, it is).
- Plural Verbs: Do not end in "-s" in the present tense (for example, they run, they talk, they are).

Subject-verb agreement is a simple rule. A singular subject takes a singular verb. A plural subject takes a plural verb.
- Singular: The dog barks loudly. (One dog, so the verb ends in 's')
- Plural: The dogs bark loudly. (Multiple dogs, so the verb has no 's')
Bluebook Test 7 shows how the test makes this harder by adding descriptive phrases. The most common trick is inserting a prepositional phrase. A prepositional phrase starts with a preposition (like in, of, on, for, with, between, among) and ends with a noun. The subject of the sentence will never be inside a prepositional phrase.
Look at this tricky example: "The box of old crayons is on the table." The subject is "box," not "crayons." Since "box" is singular, use the singular verb "is." The phrase "of old crayons" is just a distraction.
Common Mistake: Chasing the Nearest Noun
The most frequent error students make on subject-verb agreement questions is matching the verb to the noun that appears right before it, rather than the true subject. In the sentence "The box of old crayons is on the table," a student might see "crayons" right before the verb and incorrectly choose "are." The SAT relies on this reflex. Train yourself to find the subject by asking "who or what is doing the action?" before you look at the verb choices. This habit alone can eliminate most errors on these questions.
Why This Question Matters for Your Score
Subject-verb agreement appears in the Standard English Conventions domain, which accounts for roughly 26 percent of the Reading and Writing section on the Digital SAT. According to College Board's official test specifications, this domain covers grammar, usage, and punctuation. Mastering subject-verb agreement gives you a reliable path to points because the rule does not change. Unlike inference or main idea questions, grammar questions have a single correct answer based on a fixed rule. Every point you secure here is a point you do not have to fight for in harder passages later in the module.
Let's Break Down a Actual SAT Question
Bluebook Test 7, Module 1, Question 16: Nail That Subject-Verb Agreement
Zydeco music originated in the French Creole community of southwest Louisiana. One instrument that gives zydeco its unique sound is the vest frottoir. The vest frottoir, _______ a wearable washboard that is played by rubbing spoons or bottle openers against it.
- (A) have been
- (B) is
- (C) were
- (D) are
Explanation: Why 'is' is the Winner
This is a perfect example of a subject-verb agreement question. The main rule is straightforward: singular subjects need singular verbs, and plural subjects need plural verbs.
The SAT tries to trick you by putting extra information between the subject and the verb. Let's find the true subject. The sentence is about "The vest frottoir." This is ONE single thing. The phrase that comes after the blank, "a wearable washboard that is played...", is just a description.

Our subject, "vest frottoir," is singular. Therefore, we need a singular verb.
- (A) 'have been' is a plural verb. This is incorrect.
- (B) 'is' is a singular, present-tense verb. This is a perfect match for our singular subject.
- (C) 'were' is a plural, past-tense verb. This is incorrect.
- (D) 'are' is a plural verb. This is incorrect.
Mr. O's Tutor Tip:
Think like a detective. Cross out or mentally ignore the extra descriptive phrases between the subject and the verb. Underlining the subject and the blank where the verb goes can help isolate what you need to match. Here: "The vest frottoir _______." Now it's obvious you need a singular verb. This is a simple but powerful strategy that my students have used for years to achieve 150-300+ point improvements. For more practice, work the grammar questions in our SAT question bank.
How to Apply This Rule on Test Day
When you see a subject-verb agreement question in Bluebook, follow these steps. First, read the sentence and identify the subject by asking what the sentence is about. Second, look for prepositional phrases, appositives, or relative clauses between the subject and the verb. Third, mentally remove those phrases and read only the subject and the verb choice. Fourth, check whether the verb matches the subject in number. This process takes about 10 seconds once you practice it. Use the Bluebook practice tests to build speed. The more you practice, the faster you will spot the trap. Then note the error in your practice test mistake log.
FAQ: Subject-Verb Agreement on the SAT
1. What about subjects connected by 'and' or 'or'?
Subjects joined by 'and' are usually plural. For example, "The cat and the dog are friends." For subjects joined by 'or' or 'nor', the verb agrees with the subject closest to it. For example, "Neither the students nor the teacher is ready."
2. Are collective nouns like 'team' or 'committee' singular or plural?
On the Digital SAT, collective nouns are almost always treated as singular because they act as a single unit. For example, "The team practices every day." This rule is covered in all verb rules for the Digital SAT.
3. How do I handle indefinite pronouns like 'each', 'everyone', and 'anybody'?
Most indefinite pronouns are singular. Words like each, everyone, everybody, anyone, anybody, no one, nobody, someone, and somebody all take singular verbs. For example, "Each of the players has a helmet."
4. What's the fastest way to check if a verb is singular or plural?
Test it with 'he' and 'they'. If the verb works with 'he', it is singular (he is, he has, he runs). If it works with 'they', it is plural (they are, they have, they run).
5. Why does The Test Advantage focus so much on these grammar rules?
Standard English Conventions are the most predictable and learnable part of the Reading and Writing section. As a 12-year test prep veteran, I built this platform because I saw students paying overpriced tutors for generic material. By focusing on the exact patterns the SAT uses, we can achieve massive score jumps for a fraction of the cost, just $25 per month.
