Praxis Core Writing selected-response questions: grammar, revision, and research skills

October 31, 2026 · 7 minute read

Writing 5723 has three separately timed sections. The first is 40 selected-response questions in 40 minutes. Then come two 30-minute essays. The selected-response section is the part candidates most often underprepare, because it looks like school grammar and feels like it should take care of itself. It does not. It tests precise, timed decisions about usage, sentence correction, revision in context, and research skills, at about one minute per question. This guide covers what each question type asks, the error patterns that repeat, and how to practice them. The essays are a separate skill, covered in the Writing essays guide.

The short version

• 40 questions, 40 minutes, separately timed. Time left in the selected-response section does not carry over to the essays, and essay time does not flow back. Treat it as its own sprint.
• Four question types. Usage (find the error, or choose "No error"), sentence correction, revision in context, and research skills.
• Most of the questions are language and research skills. In the ETS content outline, Language and Research Skills for Writing accounts for 28 to 34 of the 40 selected-response questions. Text Types, Purposes, and Production accounts for 6 to 12, plus the two essays.
• "No error" is a real answer. Some usage sentences are correct as written. Guessing an error where there is none costs the same as missing a real one.
• Answer every question. There is no penalty for a wrong answer on selected-response questions, so a guess beats a blank. Mark hard questions and come back if time remains.

Format and content-category numbers come from the ETS Study Companion for Writing 5723. Passing scores are set by states and programs, not by ETS, so check your own requirement in the passing scores guide rather than studying toward a single national number.

The four question types

1. Usage: find the error, or confirm there is none

A sentence appears with underlined portions. One portion may contain an error in grammar, sentence construction, word use, punctuation, or capitalization. If no portion is wrong, the answer is "No error." No sentence has more than one error, which is useful: once you find a genuine error, stop hunting for a second one.

The reliable method is to read the sentence first without looking at the underlines. Often the error announces itself on a clean read. If nothing jumps out, check each underlined portion in turn, and only then choose "No error." Candidates lose the most points here by refusing to pick "No error" on principle, or by trusting their ear on sentences that sound fine in conversation but break a written rule.

2. Sentence correction: pick the best version

Here a sentence or part of a sentence is underlined and the choices offer rewrites, including keeping the original. The question is not "find the mistake" but "which version is best in standard written English." That means a choice can be grammatical and still wrong if it is wordy, awkward, or changes the meaning. Read each choice back into the full sentence before deciding. A rewrite that fixes one problem while creating another is not the answer.

3. Revision in context: fix a passage, not a sentence

These questions give a short passage, usually a draft with rough spots, and ask for the best revision of a sentence, the best sentence to add or remove, or the best order for the ideas. The unit is the paragraph, not the line. A sentence can be correct on its own and still be the wrong choice because it repeats what the passage already said, breaks the flow, or answers a question nobody asked. Read the whole passage before touching the choices, and ask what job the sentence is supposed to do in that spot.

4. Research skills: judge sources and evidence

Research questions ask which source is credible for a purpose, which detail actually supports a claim, or what belongs in a piece of writing drawn from sources. The trap is the tempting but irrelevant detail: true, interesting, and beside the point. Match the evidence to the claim being made, not to the topic in general. A source can be reliable and still be the wrong answer if it does not speak to the question asked.

The error patterns that repeat

Usage and sentence correction questions draw from a short list of rules. Learning the list beats relearning grammar from scratch.

• Subject-verb agreement. The verb agrees with the subject, not with the nearest noun. Phrases between subject and verb are decoration. Watch compound subjects and subjects joined by "or" and "nor."
• Pronoun-antecedent agreement. A singular antecedent takes a singular pronoun. Vague pronouns, where it is unclear who "they" or "it" refers to, are errors too.
• Pronoun case. Subjects take "I," "he," "she," "we," and "they." Objects of verbs and prepositions take "me," "him," "her," "us," and "them." The classic trap is "between you and I," which should be "between you and me."
• Verb tense and consistency. A sentence that starts in the past should usually stay there unless a time marker justifies a shift. "Have been living" describes something still true; a finished past action takes simple past.
• Parallel structure. Items in a list or joined by "and," "or," or "but" should match in form. A list that mixes nouns and verb phrases is broken even if every word is spelled right.
• Modifiers and placement. A modifier should sit next to what it modifies. A dangling or misplaced modifier changes the meaning, sometimes comically, and always wrongly.
• Punctuation. Commas, semicolons, and apostrophes do most of the damage here. Know when a semicolon joins two complete thoughts, when a comma splice is just two sentences glued together, and when an apostrophe marks possession rather than a plural.
• Word choice. Commonly confused pairs show up often: affect and effect, its and it is, their, there, and they are, accept and except. If two choices differ by one such word, that word is the whole question.

Do not try to memorize rules in the abstract. Keep an error log while you practice: every missed question gets one line naming the rule it tested. After fifty questions, the log shows your real pattern, usually two or three rules doing most of the damage. Those rules are your study plan.

Timing: one minute a question, with a bail rule

Forty questions in forty minutes means an average of one minute each, but not every question deserves one minute. Easy usage questions should take thirty seconds. Revision-in-context questions, which need a passage read, legitimately take longer. The discipline is a bail rule: if a question has eaten ninety seconds with no clear answer, pick your best guess, mark it, and move on. Come back only after every question has an answer. A question you never reach is a guaranteed miss. A question you guessed on is a live chance, and a second look with fresh eyes sometimes resolves what the first look could not.

One more timing note: because the sections are separately timed, do not rush the selected-response section to "save time" for the essays. There is nothing to save. Use the full forty minutes, then start the essays fresh.

A two-week routine for this section

1. Diagnose first. Take a timed set of 40 selected-response questions and log every miss by rule, not by question number. Your top two rules are the plan.
2. Drill by rule. Spend the first week on your top two rules only, in short untimed sets, until you can name the rule before you pick the answer.
3. Add timed sets. In the second week, switch to full 40-minute timed sets and practice the bail rule. Score by rule again, not just by total.
4. Read passages as a reviser. For revision-in-context, practice asking "what does this sentence do here" before looking at the choices. That habit transfers to every passage question.

The study plan guide shows where this routine fits alongside Reading and Math, and how to keep a retake window open if Writing is the subtest that needs a second attempt.

Frequently asked questions

How many selected-response questions are on Praxis Core Writing?

40, in a 40-minute section that is timed separately from the two 30-minute essays. The full Writing subtest is 100 minutes.

What kinds of selected-response questions appear on Writing 5723?

Four types: usage (find the error or choose "No error"), sentence correction (pick the best version), revision in context (improve a passage), and research skills (judge sources and evidence).

Is "No error" ever the right answer?

Yes. Some usage sentences are correct as written, and "No error" is the correct choice for those. Never invent an error to avoid picking it.

Should I guess on questions I cannot answer?

Yes. There is no penalty for a wrong answer on selected-response questions, so answer every question. Mark hard ones and return to them if time remains.

Does time left in the selected-response section carry over to the essays?

No. The three sections are separately timed. Use the full 40 minutes on selected-response questions, then start the essays fresh.

How does this section relate to the Writing essays?

They are two halves of one subtest with different skills. Selected-response tests control of standard written English and revision judgment. The essays test producing organized writing under time pressure. The essays guide covers how readers judge them.
