Organization/PurposeHow clearly the writer states and keeps an opinion, and how well the piece is put together from introduction to conclusion.1–4 points

A clear, effective structure that feels unified and complete, with a consistent, purposeful focus on the opinion.

  • The organization holds up between and within paragraphs.
  • The opinion is introduced and clearly stated, and the focus stays strong for the purpose and audience.
  • A variety of transitions is used consistently to show how ideas relate to each other.
  • The introduction and conclusion are effective.
  • Ideas move logically from beginning to end, with strong links between them and some variety in sentence structure.

An evident structure and a sense of completeness; any flaws are minor and do not hurt overall coherence, and the response is generally focused.

  • The organization is adequately sustained between and within paragraphs.
  • The opinion is clear, and the focus is mostly held for the purpose and audience.
  • Transitions are adequate and show some variety.
  • The introduction and conclusion are adequate.
  • Ideas progress adequately, with adequate links between them.

An inconsistent structure with some evident flaws; some ideas are loosely connected and the focus may drift a little.

  • The organization is only somewhat sustained between and within paragraphs.
  • The opinion may be somewhat unclear, or the focus is not held well enough for the purpose and/or audience.
  • Transitions are used inconsistently or with little variety.
  • The introduction or conclusion, if there is one, may be weak.
  • Ideas progress unevenly or follow a formula, and the links between them may be inconsistent or unclear.

Little or no discernible structure; the response may relate to the opinion but has little or no focus.

  • The opinion may be confusing or ambiguous, the response may be too brief, or the focus may shift away from the purpose or audience.
  • There are few or no transitions.
  • The introduction and/or conclusion may be missing.
  • Unrelated ideas show up often, and ideas may be in random order or hard to follow.
Not used for this criterion
Evidence/ElaborationHow well the writer supports the opinion and its reasons with facts and details from the sources, and how clearly ideas are developed.1–4 points

Thorough, convincing elaboration of the support for the opinion and its reasons, with effective use of the sources; ideas are developed clearly in precise language.

  • Evidence (facts and details) from the sources is comprehensive, relevant and specific, and it is worked into the writing.
  • Citations or attributions to the sources are clear.
  • A variety of elaboration techniques is used effectively.
  • Vocabulary clearly fits the audience and purpose.
  • An effective, appropriate style strengthens the content.

Adequate elaboration of the support for the opinion and its reasons, with use of the sources and a mix of precise and more general language.

  • Evidence from the sources is relevant and integrated, but it may be general.
  • Citations or attributions to the sources are adequate.
  • Some elaboration techniques are used adequately.
  • Vocabulary is generally appropriate for the audience and purpose.
  • The style is generally appropriate.

Uneven, cursory elaboration with partial or uneven use of the sources; ideas are developed unevenly in simple language.

  • Some evidence from the sources is weakly integrated, imprecise, repetitive, vague or copied.
  • Citations or attributions to the sources are weak.
  • Elaboration techniques are weak or uneven; the development may be mostly a summary of the sources.
  • Vocabulary is uneven or somewhat ineffective for the audience and purpose.
  • The attempt at an appropriate style is inconsistent or weak.

Minimal elaboration with little or no use of the sources; the response is vague, unclear or confusing.

  • Evidence from the sources is minimal, irrelevant, missing, used incorrectly or mostly copied.
  • Citations or attributions to the sources are insufficient.
  • Elaboration techniques are minimal, if present.
  • Vocabulary is limited or ineffective for the audience and purpose.
  • There is little or no sign of an appropriate style.
Not used for this criterion
ConventionsCommand of sentence formation, punctuation, capitalization, grammar usage and spelling, scored as one holistic judgment.0–2 pointsNot used for this criterionNot used for this criterion

Adequate command of conventions.

  • Sentence formation, punctuation, capitalization, grammar usage and spelling are adequately correct for the length of the response.

Partial command of conventions.

  • Correct use of sentence formation, punctuation, capitalization, grammar usage and spelling is limited.

Little or no command of conventions.

  • Correct use of sentence formation, punctuation, capitalization, grammar usage and spelling is infrequent.

Total: 10 points (Organization/Purpose 4 + Evidence/Elaboration 4 + Conventions 2)

  • Each trait gets its own score: up to 4 + 4 + 2 rubric points. How the trait scores feed the Writing claim and scale score on a state report is set by the test's scoring rules, so the 10-point rubric total is a classroom number, not a scale score.
  • NS (no score) is separate from the score points. The two 4-point traits run from 4 down to 1; there is no 0 on those traits. Conventions runs 2, 1, 0.
  • Smarter Balanced notes that elaboration techniques can include personal experiences that support the opinion.
  • Conventions is scored holistically, not by counting errors. Scorers weigh variety (how many kinds of errors), severity (basic errors count more than errors in advanced constructions) and density (how many errors relative to the amount of writing, so length matters).
Not scored (no score point is given):
  • Insufficient: too little of the student's own writing to score, including a response that is mostly text copied from the sources or the prompt.
  • Written in a language other than English.
  • Off-topic: the response does not address the topic of the task.
  • Off-purpose: the response is on topic but written for a different purpose than the one asked for (for example, a made-up story when the task asks for an opinion). Organization/Purpose and the elaboration trait get NS; Conventions can still be scored, because off-purpose is not one of its NS conditions.

About the Smarter Balanced opinion rubric

Third, fourth and fifth graders write this essay as the last step of the ELA performance task. They read a few short texts or watch a short video on one topic, answer some research questions, and then write an opinion piece for a stated audience, such as their principal or classmates.

Younger writers are not expected to handle counterarguments here; that comes in the middle school argumentative rubric. What separates scores at this level is whether the opinion stays clear from start to finish, whether each reason has real support from the sources, and whether the student explains that support in their own words.

Below: the rubric in plain language, a grade 4 sample with honest scores, and feedback comments you can paste into a student's paper.

How to score with it

Organization/Purpose (1–4): a clear opinion, kept all the way through

First find the opinion. In a 3 or 4 paper it shows up in the introduction and you never lose it. Papers that start with one opinion and end with another, or that say "there are good and bad things" and never choose, usually sit at 2.

Then check that reasons are grouped. A strong grade 3–5 paper gives each reason its own paragraph or section, links them with transitions such as "another reason" or "for example", and ends with a conclusion that connects back to the opinion. A list of sentences with no grouping points to a 1 or 2.

Evidence/Elaboration (1–4): do the reasons have support from the sources?

Look at each reason and ask what backs it up. A 3 uses relevant facts from the sources for most reasons and names where they came from, even simply ("The article says"). A 2 might use one fact from one source, repeat the same detail, or copy a sentence without explaining it.

At 4, the support is specific and explained: the student uses details from more than one source, tells why each detail matters, and picks words that fit the audience. A short personal experience can add to the support, but it does not take the place of source evidence.

Conventions (0–2): fair to the grade

Judge conventions against what is reasonable for the grade and the length of the piece. A fourth grader with a few spelling slips and solid sentences earns a 2. Frequent run-ons, missing end punctuation or lowercase sentence starts across the paper point to a 1.

Check for NS first

A response that is a few words long, mostly copied from the articles, not in English, off the topic, or a story instead of an opinion gets NS on the first two traits instead of a 1. Conventions can still be scored for an off-purpose response.

Fictional sample · Grade 4

Prompt

Source summary (fictional, written by EasyClass): Students read two short articles and watch a short video. "Growing Lunch" tells about a school garden where students grew lettuce and carrots and the cafeteria served them; the school reported that students tried more vegetables. "Who Waters in July?" explains that gardens need care in summer and some school gardens were abandoned. In the video, a fourth grader shows how her class measures plant growth for math. Task: Write an opinion essay for your principal about whether your school should start a garden. Use information from the sources.

I think our school should have a garden. A garden would help kids eat healthy and it would help us learn.

The first reason is kids would eat more vegetables. In the article Growing Lunch the kids grew lettuce and carrots and they ate them at lunch. the school said kids tried more vegetables. I think if we grow are own food we would want to eat it to.

Another reason is that a garden helps you learn. in the video a girl measures her plants for math. We could do that and also learn about science like how plants need sun and water.

Some people might say who will water it in the summer. Our families could take turns.

In conclusion our school should have a garden because we would eat healthy and learn. I hope you say yes!

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 at the beginning.
  • I give at least two reasons for my opinion.
  • I use facts or details from the sources to support each reason.
  • I tell which source my facts come from.
  • I use linking words like "because", "also" and "for example".
  • I keep the same opinion the whole time.
  • My ending tells my opinion again.
  • I check my capital letters, end marks and spelling.

Common mistakes

  • Expecting a counterclaim from third to fifth graders. The opinion rubric does not ask for one.
  • Scoring a strong personal story as strong evidence. Personal experience can help, but the rubric expects support from the sources.
  • Giving a 0 on Organization/Purpose or Evidence/Elaboration. Those traits go from 4 down to 1, with NS for responses that cannot be scored.
  • Using the old four-criterion SBAC rubric with level names like "Exceeds". The current rubric has three traits and only numbers.
  • Taking off Organization/Purpose points for spelling. Errors only count under Conventions.

Feedback comment bank

Organization/Purpose

  • 4 points

    Your opinion is clear from start to finish, and each reason has its own paragraph. Your ending ties everything together.

  • 3 points

    Your opinion is clear and your reasons are in order. Try using different linking words so your reader sees how each reason connects.

  • 2 points

    I am not sure which side you chose. Tell your opinion in your first sentence and keep it the same until the end.

Evidence/Elaboration

  • 3 points

    You used facts from the articles to support your reasons. Next time, explain why each fact matters.

  • 2 points

    Your reasons need more support. Find one fact from the sources for each reason and tell where it came from.

  • 1 point

    Your writing tells what you think but does not use the sources. Go back to the articles and find facts that agree with you.

Conventions

  • 2 points

    Your sentences are complete and your capitals and end marks are correct. Great proofreading.

  • 1 point

    Some sentences run together and some start without a capital letter. Read your paper aloud and add a period where you stop.

Questions teachers ask

Does the Smarter Balanced opinion rubric have level names like "Meets" or "Exceeds"?

No. The rubric uses score numbers only: 4, 3, 2 and 1 for the first two traits and 2, 1, 0 for Conventions. Level names on some older copies were added by others.

How many sources does a grade 3–5 student need to use?

The rubric does not set a number. It asks for relevant, specific evidence from the sources that is credited. In practice, papers scoring 3 or 4 usually draw on more than one source.

Do third graders get the same rubric as fifth graders?

Yes, one rubric covers grades 3–5. Scorers apply it with grade-level expectations in mind, and the sources and tasks differ by grade.

What is the difference between this and the grades 6–11 argumentative rubric?

The traits and points match, but middle and high school students write a claim instead of an opinion, are expected to analyze evidence, and from grade 7 must address opposing arguments.
