What this rubric measures
The STAAR Argumentative/Opinion Writing Rubric, Grades 3–5 is the official scoring guide used to evaluate student writing on Texas STAAR assessments. It is an Analytic rubric that scores responses across 2 distinct criteria, allowing teachers to give precise, targeted feedback on each area of writing.
All 2 scoring criteria
Click any criterion to expand its score level descriptors. The language below is taken verbatim from the official Texas Education Agency STAAR scoring guide.
1 Development and Organization of Ideas
The response demonstrates the following:
- Argument/opinion is clear and fully developed. The argument/opinion is clearly identifiable. The focus is consistent throughout, creating a response that is unified and easy to follow.
- Organization is effective. A purposeful structure that includes an effective introduction and conclusion is evident. The organizational structure is appropriate and effectively supports the development of the argument/opinion. The sentences, paragraphs, or ideas are logically connected in purposeful and highly effective ways.
- Evidence is specific, well chosen, and relevant. The response includes relevant text-based evidence that is clearly explained and consistently supports and develops the argument/opinion. For pairs in grades 3-5, evidence is drawn from at least one text. The response reflects a thorough understanding of the writing purpose.
- Expression of ideas is clear and effective. The writer's word choice is specific, purposeful, and enhances the response. Almost all sentences and phrases are effectively crafted to convey the writer's ideas and contribute to the overall quality of the response and the clarity of the message.
The response demonstrates the following:
- Argument/opinion is present and partially developed. An argument/opinion is presented, but it may not be clearly identifiable because it is not fully developed. The focus may not always be consistent and may not always be easy to follow.
- Organization is limited. A purposeful structure that includes an introduction and conclusion is present. An organizational structure may be apparent, but it may not be consistent and may not always support the logical development of the argument/opinion. Sentence-to-sentence connections and clarity may be lacking.
- Evidence is limited and may include some irrelevant information. The response may include some text-based evidence to support the argument/opinion, but it may be insufficiently explained, and/or some evidence may be irrelevant to the argument/opinion. For pairs, evidence is drawn from at least one of the texts. The response reflects partial understanding of the writing purpose.
- Expression of ideas is basic. The writer's word choice may be general and imprecise and at times may not convey the writer's ideas clearly. Sentences and phrases are at times ineffective and may interfere with the writer's intended meaning and weaken the message.
The response demonstrates the following:
- Argument/opinion is evident but not developed. An argument/opinion is present but not developed appropriately in response to the writing task.
- Organization is minimal and/or weak. An introduction or conclusion may be present. An organizational structure that supports logical development is not always evident or is not appropriate to the task.
- Evidence is insufficient and/or mostly irrelevant. Little text-based evidence is presented, or the evidence presented is mostly extraneous and/or repetitious. Explanation of any evidence presented is insufficient and may be only vaguely related to the writing task. The response reflects a limited understanding of the writing purpose.
- Expression of ideas is ineffective. The writer's word choice is vague or limited and may impede the quality and clarity of the essay. Sentences and phrases are often ineffective, interfere with the writer's intended meaning, and impact the strength and clarity of the message.
The response demonstrates the following:
- An argument/opinion may be evident.
- The response lacks an introduction and conclusion. An organizational structure is not evident.
- Evidence is not provided or is irrelevant. The response reflects a lack of understanding of the writing purpose.
- The expression of ideas is unclear and/or incoherent.
Four sub-criteria are embedded in each score point, clarity of the argument/opinion, effectiveness of organization, specificity of text-based evidence, and effectiveness of expression. To earn the higher score, the response must satisfy all four.
2 Conventions
Student writing demonstrates consistent command of grade-level-appropriate conventions, including correct sentence construction, punctuation, capitalization, grammar, and spelling. The response has few errors, but those errors do not impact the clarity of the writing.
Student writing demonstrates inconsistent command of grade-level-appropriate conventions, including limited use of correct sentence construction, punctuation, capitalization, grammar, and spelling. The response has several errors, but the reader can understand the writer's thoughts.
Student writing demonstrates little to no command of grade-level-appropriate conventions, including infrequent use of or no evidence of correct sentence construction, punctuation, capitalization, grammar, and spelling. The response has many errors, and these errors impact the clarity of the writing and the reader's understanding of the writing.
Important STAAR scoring rule, if a response receives a score point 0 in the Development and Organization of Ideas trait, the response will also earn 0 points in the Conventions trait.
How to score with the STAAR Argumentative/Opinion Writing Rubric, Grades 3–5.
A practical guide for teachers and norming teams. How to apply each descriptor consistently, the pitfalls that hurt inter-rater reliability, and a workflow for calibrating with colleagues.
Two-trait analytic, scored independently
- Score Development and Organization (0 to 3) first, then Conventions (0 to 2). Sum for the rubric total out of 5.
- Conventions has only 3 score points (0, 1, 2) on a tighter scale than Development.
- Critical TEA rule: a response that earns 0 on Development AUTOMATICALLY earns 0 on Conventions. There is no way to earn Conventions points on a response that fails Development.
Apply the sub-criteria together
- Development's four sub-criteria (idea, organization, evidence, expression) are NOT scored independently. They describe what writing at each score point looks like across all four areas.
- To earn a 3, the response must satisfy all four sub-criteria consistently. A response with strong evidence but weak organization typically caps at 2.
- Start at the lowest score point and ask, does the response meet all four sub-criteria for this level? Move up only when it clearly does.
Common pitfalls to avoid
- Awarding 3 to a response with strong organization but no text-based evidence, evidence is one of the four required sub-criteria.
- Counting evidence quantity instead of quality. Grades 3-5 require evidence from at least one provided text, but the rubric rewards SPECIFIC and RELEVANT evidence, not volume.
- Forgetting the 0-on-Development → 0-on-Conventions rule when scoring responses that lack structure but have decent mechanics.
Tips for norming with your team
- Anchor with 3 to 5 sample responses scored by your most experienced grader before the session.
- Score the first 5 silently, then compare. Discuss any trait where graders are more than one point apart.
- Re-norm halfway through a long batch. Drift is real.
Notes for the STAAR Argumentative/Opinion Rubric, Grades 3–5
STAAR Grades 3-5 Argumentative/Opinion is technically opinion writing at this grade band. The rubric does not require counterarguments (those appear starting at Grade 8 in the 6-EII rubric).
STAAR prompts at Grades 3-5 typically provide one or two short source texts. The rubric expects evidence drawn from at least one text. Responses that ignore the sources or substitute personal opinion for source-based evidence typically cap Development at 2.
Conventions on STAAR are scored on a 3-point scale (0, 1, 2). Even strong mechanics cannot recover an overall score: a response with severe Development weakness will earn 0 on both traits per the TEA rule.
Universal STAAR scoring rule: a response that earns 0 on Development and Organization of Ideas earns 0 on Conventions regardless of mechanical quality.

Why students should pick where they sit at lunch
Right now at my school, the teachers decide where everyone sits at lunch. I think fourth graders should get to choose their own seats in the cafeteria, because we are old enough, it helps us make new friends, and the article shows that other schools have done it.
We are old enough to choose
Fourth graders are not little kids anymore. We pick our own partners for group projects and choose which book to read for our reading log. Picking where to sit at lunch is the same kind of choice. If we can make these decisions in class, we can make them in the cafeteria.
It helps us make friends
The article says that when one school let kids pick their seats, more students started talking to kids they had not talked to before. Some kids made new friends just by sitting next to someone different. Lunch is one of the only times we can talk to friends, and it should be the time we choose who to sit with.
Other schools already do this
The article describes a school in Round Rock that lets students pick their seats and says it works well. The teachers walk around to help if there is a problem. If their school can do it, our school can too.
Conclusion
Fourth graders are old enough, picking our seats helps us make friends, and other schools already do it. Our school should let us choose where we sit at lunch.
Clear opinion, all four sub-criteria met
Opinion is stated clearly in the intro and maintained throughout. Organization uses three reasons each in its own paragraph with a satisfying conclusion. Evidence from the article (Round Rock school, new-friend example) is specific and relevant. Word choice is grade-appropriate.
Consistent command of grade-level conventions
Capitalization, punctuation, sentence formation, and spelling are correct throughout. There are no patterns of errors. Earns full credit on the STAAR 0-2 Conventions sub-scale.
