How to Master the SHSAT ELA Revising/Editing Section: Top 10 Grammar Rules Tested

The Specialized High Schools Admissions Test (SHSAT) is an important part of the admissions process for New York City’s specialized high schools. The English Language Arts (ELA) section evaluates a student’s ability to understand written passages, recognize grammatical errors, improve sentence structure, and communicate ideas clearly. Strong grammar skills can help students approach the Revising/Editing questions with greater accuracy and confidence.

Many students understand basic grammar rules but struggle to apply them under timed testing conditions. The key to improving performance is to recognize common grammatical patterns, understand how sentences work, and practice identifying errors in context. As a tutor, I recommend focusing on the grammar concepts that students are most likely to encounter in editing and revision exercises rather than memorizing isolated rules.

In this guide, I explain how to master the SHSAT ELA Editing section, explore 10 essential grammar rules, and share practical strategies that can help students prepare effectively.

Understanding the SHSAT ELA Revising/Editing Section

The SHSAT ELA section measures more than a student’s ability to identify grammatical mistakes. It also evaluates reading comprehension, logical organization, sentence clarity, and the ability to make effective revisions. Revising focuses on improving the quality, organization, and effectiveness of writing, while editing focuses on correcting errors in grammar, punctuation, capitalization, and usage.

Students should approach these tasks by reading the surrounding sentences carefully. A sentence may appear grammatically correct on its own but create confusion within a paragraph. Similarly, an editing question may test whether a student can recognize a subject-verb agreement error or select the correct punctuation without changing the author’s intended meaning.

I encourage students to develop a consistent editing process. First, read the entire sentence to understand its meaning. Next, identify the grammatical structure and look for possible errors. Finally, compare the answer choices and select the option that makes the sentence correct, clear, and consistent with the passage.

Students should also remember that the SHSAT uses a specific test format that can change over time. Families should consult the latest official SHSAT information and current practice materials when planning preparation.

Top 10 Grammar Rules Students Should Master

Understanding the following 10 grammar rules can help students identify errors more efficiently and make stronger editing decisions. I recommend practicing each rule with complete sentences and short passages.

1. Subject-Verb Agreement

A verb must agree with its subject in number. Singular subjects generally take singular verbs, while plural subjects take plural verbs.

• Incorrect: The group of students are preparing for the exam.
• Correct: The group of students is preparing for the exam.

Students should identify the main subject instead of getting distracted by phrases between the subject and verb.

2. Verb Tense Consistency

Verb tenses should remain consistent unless the timing of an action requires a change.

• Incorrect: Maya studied for the test and practices grammar every day.
• Correct: Maya studied for the test and practiced grammar every day.

Students should check whether the sentence describes past, present, or future actions and maintain the appropriate tense.

3. Pronoun-Antecedent Agreement

A pronoun must clearly refer to an antecedent and agree with it in number and person.

• Incorrect: Each student should bring their notebook.
• Correct in traditional formal usage: Each student should bring his or her notebook.

In modern American English, singular they is widely accepted. Students should follow the usage and conventions established by the question and its answer choices.

4. Pronoun Case

Pronouns must function correctly as subjects or objects in a sentence.

• Incorrect: The teacher gave the worksheet to Sarah and I.
• Correct: The teacher gave the worksheet to Sarah and me.

A useful strategy is to remove the other person’s name temporarily. This makes it easier to identify the correct pronoun.

5. Sentence Fragments

A complete sentence needs an independent clause with a subject and a predicate that expresses a complete thought.

• Incorrect: Because Jordan practiced grammar every evening.
• Correct: Jordan improved because he practiced grammar every evening.

Students should watch for dependent clauses that cannot stand alone and identify ways to connect them to complete thoughts.

6. Run-On Sentences and Comma Splices

A run-on sentence incorrectly joins independent clauses without suitable punctuation or a conjunction. A comma splice joins two independent clauses with only a comma.

• Incorrect: The student reviewed the passage, she found the error.
• Correct: The student reviewed the passage, and she found the error.

Students can correct these errors with a period, a semicolon, or a comma followed by an appropriate coordinating conjunction.

7. Comma Usage

Commas separate introductory elements, items in a series, and certain clauses and phrases. They also help prevent confusion in sentence structure.

• Incorrect: Before the exam began the students checked their answers.
• Correct: Before the exam began, the students checked their answers.

Students should learn when commas are necessary and avoid inserting them between a subject and its verb or a verb and its object.

8. Apostrophes and Possessives

Apostrophes indicate possession or form contractions. Students should distinguish singular and plural possessives from ordinary plural nouns.

• Incorrect: The students book was on the desk.
• Correct: The student’s book was on the desk.

For plural possessives, the apostrophe usually follows the s, as in the students’ books. Students should also distinguish its (possessive) from it’s (it is or it has).

9. Modifiers and Parallel Structure

Modifiers should appear close to the words they describe. Parallel structure requires items in a list or series to follow consistent grammatical patterns.

• Incorrect: Running through the park, the backpack fell off Daniel’s shoulder.
• Correct: Running through the park, Daniel felt his backpack fall off his shoulder.

For parallel structure, compare She enjoys reading, writing, and solving puzzles with a sentence that mixes inconsistent verb forms. Consistent structure makes writing easier to understand.

10. Word Choice and Commonly Confused Words

Students should recognize words that sound similar or have related meanings but perform different grammatical functions.

• There: Refers to a place or introduces an idea.
• Their: Shows possession.
• They’re: Means they are.
• Your: Shows possession.
• You’re: Means you are.
• Its: Shows possession.
• It’s: Means it is or it has.

Students should also pay attention to context when choosing between words such as affect and effect. The correct choice must fit the sentence’s meaning and grammatical structure.

How to Apply Grammar Rules During the SHSAT

Knowing grammar rules is only the first step. Students also need to apply those rules quickly and accurately while working through a passage. I recommend reading the entire sentence before examining an underlined phrase or evaluating answer choices. This helps students understand the writer’s meaning and avoid correcting something that is already appropriate in context.

A practical approach is to identify the possible error, name the grammar rule involved, and then test the answer choices against that rule. Students should eliminate choices that introduce new errors, change the intended meaning, or make a sentence unnecessarily complicated. If a question asks for the best revision, the strongest answer should improve clarity and effectiveness rather than simply use more sophisticated vocabulary.

Timed practice can help students build this process into a habit. However, accuracy should come before speed. Once students consistently recognize common errors, they can gradually reduce the time they spend analyzing each question.

Common Revising and Editing Mistakes to Avoid

Even students with strong grammar knowledge can lose valuable points when they rush or overlook context. I encourage families to help students recognize these common mistakes during practice.

• Relying on what sounds right: A sentence may sound natural but still contain a grammatical error. Students should apply a specific rule.
• Ignoring the complete passage: A revision must fit the surrounding sentences and preserve the author’s intended meaning.
• Overlooking small words: Articles, pronouns, prepositions, and verb endings can change a sentence’s correctness.
• Choosing unnecessarily complex wording: The best revision is usually clear, concise, and grammatically correct.
• Spending too long on one question: Students should manage their time and return to difficult questions when the test format and remaining time allow.
• Repeating mistakes without reviewing them: Students should maintain an error log and revisit the grammar rules behind incorrect answers.

Effective SHSAT ELA Practice Strategies

Consistent practice helps students turn grammar knowledge into a reliable test-taking skill. I recommend using a structured study plan that combines targeted grammar exercises, passage-based editing, and regular review.

• Practice one grammar rule at a time: Begin with subject-verb agreement, punctuation, and sentence structure before moving to more complex editing exercises.
• Use timed practice passages: Introduce time limits gradually to build confidence and improve decision-making.
• Maintain a grammar error log: Record each incorrect answer, the rule involved, and the reason the correct choice works.
• Review explanations carefully: Understanding why an answer is correct is more valuable than simply memorizing the answer.
• Complete full-length practice tests: Use appropriate SHSAT practice materials to develop concentration, pacing, and familiarity with the exam format.
• Track progress weekly: Compare accuracy across different grammar topics to identify areas that need additional attention.

Parents can support preparation by helping students establish a consistent study schedule and encouraging them to review mistakes without becoming discouraged. Targeted instruction and personalized feedback can also help students address persistent weaknesses.

Conclusion

Mastering the SHSAT ELA Revising/Editing section requires more than memorizing grammar definitions. Students need to recognize grammatical patterns, understand sentence structure, evaluate revisions in context, and apply their knowledge under timed conditions.

By focusing on the 10 essential grammar rules in this guide, practicing with passages, and reviewing mistakes regularly, students can strengthen their editing skills and approach the SHSAT with greater confidence. A consistent preparation plan, supported by clear explanations and targeted practice, can make a meaningful difference in a student’s readiness for the exam.
