4.1 Grammar Fundamentals

Why Grammar Anchors the Writing Domain

The Writing section is one of three equally weighted domains on the ETS ParaPro Assessment (1755), supplying roughly 30 of the 90 questions, about a third of the test. (Note: ETS is retiring the 1755 on August 31, 2026 and replacing it with ParaPathways 5757; the grammar skills below transfer directly.) Within Writing, items split almost evenly between content knowledge — can you spot and fix an error — and classroom application — can you help a student understand the rule. Grammar fundamentals power both halves, so this is the highest-leverage place to study.

A paraprofessional (also called a paraeducator, teacher aide, or instructional assistant) reinforces what the lead teacher introduces. You will not be asked to diagram sentences or recite obscure terminology. You will be asked to recognize standard written English, identify the single best correction among four choices, and choose the support strategy a good aide would use.

The Eight Parts of Speech

Every word in English does one of eight jobs. Knowing the job a word performs lets you reason about agreement, case, and modifier placement instead of guessing.

A quick tell: adverbs often end in -ly and answer how, when, or where (she read quietly). Prepositions almost always begin a phrase that ends in a noun (under the desk), and that whole phrase can be crossed out to find the true subject.

Subject-Verb Agreement

The core rule is simple: a singular subject takes a singular verb, and a plural subject takes a plural verb (the dog runs vs. the dogs run). The exam earns its difficulty by hiding the subject. Master these traps:

The single most common ParaPro distractor is a prepositional phrase that drops a plural noun right before the verb: The list of supplies is long — not are long, because the subject is list, not supplies.

Pronoun-Antecedent Agreement and Case

A pronoun must match its antecedent (the noun it replaces) in number, person, and gender. Each student brought his or her notebook is traditionally correct for a singular antecedent; The students brought their notebooks is plural. With or/nor, the pronoun again follows the nearer noun.

Pronoun case trips many test-takers:

A reliable trick: cover the other person and read the pronoun alone. Me went to recess sounds wrong, so the answer is He and I went to recess. Likewise to she fails, so write give it to her.

Verb Tense Consistency

Keep tense consistent unless the sentence genuinely shifts in time. She finished her work and walks home is wrong (past, then present); make it She finished her work and walked home. Watch the perfect tenses too: present perfect (has graded) links the past to now, and past perfect (had graded) marks an action completed before another past action.

Supporting Grammar Instruction in the Classroom

Application items reward concrete, supportive scaffolding. The best answer almost always:

1. Teaches one rule at a time before combining concepts.
2. Makes the rule visible with anchor charts or color-coded subjects and verbs.
3. Uses the student's own sentence so the lesson feels relevant.
4. Reads aloud, because the ear often catches an agreement error the eye misses.
5. Builds on prior knowledge instead of correcting in a way that embarrasses the student.

Reject any answer choice that publicly singles out a student, hands them the answer with no reasoning, or piles on multiple rules at once.

Worked Example: A student writes, "The group of fourth-graders are lining up for lunch." On a content item you must fix the verb: the subject is group (singular), so it becomes "The group of fourth-graders is lining up." On the paired application item, the best support is not "Tell her it's wrong." It is to cover the prepositional phrase of fourth-graders with your finger so she sees group ... is, then have her reread it aloud. That isolates the true subject and lets her self-correct — the hallmark of a strong paraeducator response.
