STAAR ECR Rubric, Grades 3–5 (Argumentative/Opinion)

The STAAR grades 3–5 opinion essay is scored on a 5-point rubric: Development and Organization of Ideas (0–3) and Conventions (0–2). On the test two scores are added, so the essay counts for up to 10 points. A 0 in the first trait means a 0 in Conventions too.

Criterion3 points2 points1 point0 pointsScore
Development and Organization of IdeasHow clearly the opinion is stated and supported, how well the essay is organized, how well text evidence is used and explained, and how clearly ideas are expressed.0–3 points

Argument/opinion is clear and fully developed. Organization is effective. Evidence is specific, well chosen, and relevant. Expression of ideas is clear and effective.

  • The opinion is easy to find and the writer stays with it from start to finish, so the essay reads as one connected piece.
  • The structure suits the task: an introduction that sets up the opinion, a conclusion that closes it, and transitions that link sentences and paragraphs in a logical order.
  • Reasons are backed by details from the passage that fit the opinion and are explained, which shows the writer understood what the prompt asked for.
  • When the prompt is based on two passages, the evidence can come from one passage or both.
  • Word choice is precise and deliberate, and nearly every sentence helps make the writer's point.

Argument/opinion is present and partially developed. Organization is limited. Evidence is limited and may include some irrelevant information. Expression of ideas is basic.

  • A reader can find the opinion, but it may be stated loosely, only partly supported, or lost for stretches of the essay.
  • An introduction and conclusion are there, but the body may not build logically and some sentences do not connect to the ones around them.
  • Some text evidence is used, but it is thinly explained, partly off target, or does not always back the opinion; the writer's grasp of the task is partial.
  • When the prompt is based on two passages, evidence comes from at least one of them.
  • Words are general or imprecise, and some sentences blur what the writer means.

Argument/opinion is evident but not developed. Organization is minimal and/or weak. Evidence is insufficient and/or mostly irrelevant. Expression of ideas is ineffective.

  • An opinion appears, but the writer does little to support it in a way that fits the task.
  • An introduction or a conclusion may appear, but the structure does not help ideas build and may not suit the task.
  • Little of the support comes from the text; much of it is repeated, off topic, or explained in ways only loosely tied to the prompt.
  • Vague or limited wording makes the essay hard to follow.

The response has no workable structure and no relevant support for its opinion.

  • An opinion might be visible, but there is no introduction, no conclusion and no structure a reader can follow.
  • Evidence is missing or has nothing to do with the prompt.
  • The writing is unclear or does not hold together.
  • A 0 here also sets Conventions to 0.
ConventionsSentence construction, punctuation, capitalization, grammar and spelling, judged against what is appropriate for the grade.0–2 pointsNot used for this criterion

Student writing demonstrates consistent command of grade-level-appropriate conventions.

  • Sentences are built correctly for the grade, and punctuation, capitalization, grammar and spelling are mostly right.
  • The few errors that appear do not get in the way of meaning.

Student writing demonstrates inconsistent command of grade-level-appropriate conventions.

  • Correct conventions show up in some places and not in others.
  • There are several errors, but a reader can still follow the writer's thinking.

Student writing demonstrates little to no command of grade-level-appropriate conventions.

  • Errors are frequent and make parts of the essay hard to understand.
  • This is also the score whenever Development and Organization of Ideas is 0.

Total: 5 points (Development and Organization of Ideas 3 + Conventions 2)

  • The rubric is worth 5 points. On the STAAR test each essay gets two scores that are added, so the item is reported out of 10.
  • A 0 in Development and Organization of Ideas means the essay also gets a 0 in Conventions.
  • TEA publishes a separate informational rubric for grades 3–5 with the same two traits and point values. A student writes in only one mode on test day, so use the informational rubric when the prompt asks the student to explain rather than argue.
  • Since December 2023 an automated scoring engine scores every English-version response first, and trained human scorers score at least 25% of responses. A human score, when there is one, becomes the score of record.

About the STAAR argumentative/opinion rubric

Third, fourth and fifth graders taking STAAR Reading Language Arts read one passage or a pair of passages and then write an essay about them. TEA calls this the extended constructed response, or ECR. The prompt asks for either an opinion essay or an informational essay, and each mode has its own rubric. This page covers the argumentative/opinion rubric, which is the one the EasyClass grader uses for this page.

The rubric is short on purpose. Almost everything a teacher would call ideas, structure, evidence and word choice sits inside one 3-point trait. Spelling, punctuation and grammar get their own 2-point trait. That means a student who writes a neat, error-free essay with weak reasons can still land at 2 or 3 out of 5, while a student with a strong opinion and messy commas can earn 4.

In the elementary grades the bar for evidence is lower than in middle school. When the prompt pairs two passages, a top-scoring essay can draw evidence from just one of them, and there is no counterargument requirement at any score point.

How to score with it

Development and Organization: a 3 versus a 2

Start with the opinion. In a 3, you can point to the sentence where the student says what they think, and every body paragraph goes back to it. In a 2, the opinion is there but it wobbles: the student agrees in the introduction, then spends a paragraph retelling the story.

Then look at the evidence. A 3 picks details from the passage that actually prove the reason and says why they matter ("This shows that..."). A 2 drops in a detail and moves on, or uses a detail that is true but doesn't help the argument. If you find yourself thinking "so what?" after the quoted detail, the essay is more likely a 2.

Development and Organization: a 2 versus a 1

A 2 has a recognizable shape, with an introduction and a conclusion around some body sentences. A 1 might have only one of those, or a single block of text where ideas don't build.

The other difference is how much of the support comes from the passage. A 1 often repeats the opinion in different words, or leans on personal stories with little from the text. Be careful with long essays: length alone does not lift a 1 to a 2 if most of it is repetition.

When Development and Organization is 0

Give a 0 when there is no introduction, no conclusion and no structure, and the evidence is missing or unrelated. An opinion may still be visible. Once this trait is 0, Conventions is automatically 0, so the essay earns nothing, even if the few sentences written are spelled correctly.

Scoring Conventions

Judge conventions against what a third, fourth or fifth grader is expected to control, not against adult writing. Ask one question: do the errors get in the way? A 2 has few errors and none that stop you. A 1 has several errors, but you can still follow the student's thinking. A 0 has so many errors that you have to reread to work out what the student meant.

How the test counts it

Each essay gets two rubric scores that are summed, so a 3 and a 2 on the page above becomes 10 points on the test. Reporting it out of 10 matches what families see on score reports. In class, scoring out of 5 is enough to see where a student is.

Prompt

Fictional source (written by EasyClass): "The Lot on Pecan Street" tells how the town of Mesa Verde has an empty lot next to the library. The town council can turn it into a vegetable garden run by students or a small skate park. The article says the garden would give food to the food pantry and teach science, and that the skate park would give older kids a safe place to ride but would cost twice as much. Prompt: Should the town build the garden? Write an essay that states your opinion and supports it with evidence from the article.

I think the town should build the garden on Pecan Street. The garden is a better idea for alot of reasons.

First the garden would help people who need food. The article says the vegetables would go to the food pantry. That means families could get fresh food. My family likes tomatoes from my grandma's garden they taste better then the store.

Second the garden is cheaper. The skate park costs twice as much money. The town could use the extra money for other things like books for the library.

Also kids would learn about science. They would learn how plants grow and about dirt and water. Skate parks are fun to but you can get hurt.

In conclusion the town should build the garden because it helps people and costs less.

Teacher tools for this rubric

A checklist to hand to students, comments you can reuse when you give feedback, and the mistakes that cost points most often.

Student checklist

  • I tell my opinion clearly at the beginning.
  • Every reason I give connects back to my opinion.
  • I use details from the passage to support each reason.
  • I explain how each detail proves my reason.
  • I have an introduction and a conclusion.
  • I use transition words to connect my ideas.
  • I reread for capital letters, end marks and spelling.

Common mistakes

  • Giving a 3 for a clear opinion even though the evidence is listed without explanation.
  • Lowering Development and Organization because of spelling and punctuation errors; those belong in Conventions.
  • Scoring Conventions above 0 when Development and Organization is 0.
  • Expecting evidence from both passages in a paired-passage prompt; at grades 3–5 one passage is enough for a 3.
  • Scoring an informational prompt with this opinion rubric. Check the mode of the prompt first.

Feedback comment bank

Development and Organization of Ideas

  • 3 points

    Your opinion is clear from the first sentence, and every paragraph gives a reason with proof from the passage. Your explanation of the detail in paragraph 4 really convinced me.

  • 2 points

    I can tell what you think, and you used a detail from the passage. Next step: after each detail, add a sentence that starts with "This shows..." to explain how it proves your opinion.

  • 1 point

    You shared your opinion, but most of the essay repeats it. Go back to the passage and find two details that prove you are right.

Conventions

  • 2 points

    Your sentences are complete and your punctuation is careful, which makes your essay easy to read.

  • 1 point

    A few run-on sentences and missing capitals slowed me down. Read your essay out loud and put a period where you take a breath.

  • 0 points

    Many spelling and sentence errors make this hard to understand. Let's pick one thing, ending each sentence with a period, and practice it.

What differs from the official version
  • Criterion names, point values, score order and the score-point headline phrases follow TEA. The descriptor bullets are written in our own words because TEA marks its scoring materials "All rights reserved."
  • TEA's score 0 in Development and Organization has no headline phrase; the headline shown for 0 is ours.
  • TEA's rubric lists the four parts of each score point (argument, organization, evidence, expression) as separate rows. We combined the headline phrases into one line per score.
  • We compared this page with the rubric as it appears in TEA's 2026 Grade 3 and Grade 5 scoring guides. The standalone rubric PDF did not load for us; it is linked above.
  • This page and the EasyClass grader use the argumentative/opinion rubric. For informational prompts use TEA's Grades 3–5 Informational Writing Rubric: https://tea.texas.gov/student-assessment/tx-staar-informational-rubric-g3-5.pdf
Good to know
  • House Bill 8 (2025) replaces STAAR with the Student Success Tool (SST) beginning in the 2027–28 school year; until then the grades 3–5 essay is scored with this rubric (TEA HB 8 FAQ, August 2026: https://tea.texas.gov/data-reports/staar/hb-8-faq-update.pdf).
  • TEA has posted a DRAFT SST Argumentative/Opinion Writing Rubric for grades 3–5 (August 2026). It is worth 3 points: Organization and Development of Ideas 0–2 and Conventions 0–1 (https://tea.texas.gov/data-reports/staar/sst-3-5-argumentative-opinion-writing-rubric.pdf).

Questions teachers ask

Is the STAAR ECR rubric the same for 3rd, 4th and 5th grade?

Yes. TEA publishes one argumentative/opinion rubric for grades 3–5 and one informational rubric for the same band. What changes from grade to grade is the passage and what counts as grade-level conventions.

Why is the essay out of 10 if the rubric is only 5 points?

Each essay receives two scores on the 5-point rubric and the two are added together. TEA's 2026 scoring guides describe this, and the released answer keys list the essay at 10 points.

Do 3rd graders have to write a counterargument?

No. The grades 3–5 opinion rubric does not mention counterarguments at any score point. TEA's rubric for grades 6 through English II asks for one starting in grade 8.

How do I know if the prompt is opinion or informational?

Read the prompt's task line. Opinion prompts ask whether the student agrees, which choice is better, or whether a character was right. Informational prompts ask the student to explain or describe something from the text. Score each with its own rubric.

Will this rubric still be used after STAAR ends?

Not as is. TEA says the switch begins in the 2027–28 school year. TEA's draft rubric for the replacement test, the Student Success Tool, scores the essay out of 3 instead of 5, with the same idea of separate development and conventions scores.
