What this rubric measures
The SBAC Opinion Performance Task Writing Rubric, Grades 3–5 is the official scoring guide used to evaluate student writing on California CAASPP (SBAC) assessments. It is an Analytic rubric that scores responses across 3 distinct criteria, allowing teachers to give precise, targeted feedback on each area of writing.
All 3 scoring criteria

1 Organization/Purpose
The response has a clear and effective organizational structure, creating a sense of unity and completeness. The organization is sustained between and within paragraphs. The response is consistently and purposefully focused:
- opinion is introduced, clearly communicated, and the focus is strongly maintained for the purpose and audience
- consistent use of a variety of transitional strategies to clarify the relationships between and among ideas
- effective introduction and conclusion
- logical progression of ideas from beginning to end; strong connections between and among ideas with some syntactic variety
The response has an evident organizational structure and a sense of completeness. Though there may be minor flaws, they do not interfere with the overall coherence. The organization is adequately sustained between and within paragraphs. The response is generally focused:
- opinion is clear, and the focus is mostly maintained for the purpose and audience
- adequate use of transitional strategies with some variety to clarify relationships between and among ideas
- adequate introduction and conclusion
- adequate progression of ideas from beginning to end; adequate connections between and among ideas
The response has an inconsistent organizational structure. Some flaws are evident, and some ideas may be loosely connected. The organization is somewhat sustained between and within paragraphs. The response may have a minor drift in focus:
- opinion may be somewhat unclear, or the focus may be insufficiently sustained for the purpose and/or audience
- inconsistent use of transitional strategies and/or little variety
- introduction or conclusion, if present, may be weak
- uneven progression of ideas from beginning to end; and/or formulaic; inconsistent or unclear connections between and among ideas
The response has little or no discernible organizational structure. The response may be related to the opinion but may provide little or no focus:
- opinion may be confusing or ambiguous; response may be too brief or the focus may drift from the purpose and/or audience
- few or no transitional strategies are evident
- introduction and/or conclusion may be missing
- frequent extraneous ideas may be evident; ideas may be randomly ordered or have an unclear progression
At Grades 3-5, students write Opinion responses (not Argumentative). Counterargument expectations begin at Grade 7 on the Argumentative rubric and do not apply at this grade band.
2 Evidence/Elaboration
The response provides thorough and convincing elaboration of the support/evidence for the opinion and supporting idea(s) that includes the effective use of source material. The response clearly and effectively develops ideas, using precise language:
- comprehensive evidence (facts and details) from the source material is integrated, relevant, and specific
- clear citations or attribution of source material
- effective use of a variety of elaborative techniques
- vocabulary is clearly appropriate for the audience and purpose
- effective, appropriate style enhances content
The response provides adequate elaboration of the support/evidence for the opinion and supporting idea(s) that includes the use of source material. The response adequately develops ideas, employing a mix of precise with more general language:
- adequate evidence (facts and details) from the source material is integrated and relevant, yet may be general
- adequate use of citations or attribution to source material
- adequate use of some elaborative techniques
- vocabulary is generally appropriate for the audience and purpose
- generally appropriate style is evident
The response provides uneven, cursory elaboration of the support/evidence for the opinion and supporting idea(s) that includes partial or uneven use of source material. The response develops ideas unevenly, using simplistic language:
- some evidence (facts and details) from the source material may be weakly integrated, imprecise, repetitive, vague, and/or copied
- weak use of citations or attribution to source material
- weak or uneven use of elaborative techniques; development may consist primarily of source summary
- vocabulary use is uneven or somewhat ineffective for the audience and purpose
- inconsistent or weak attempt to create appropriate style
The response provides minimal elaboration of the support/evidence for the opinion and supporting idea(s) that includes little or no use of source material. The response is vague, lacks clarity, or is confusing:
- evidence (facts and details) from the source material is minimal, irrelevant, absent, incorrectly used, or predominantly copied
- insufficient use of citations or attribution to source material
- minimal, if any, use of elaborative techniques
- vocabulary is limited or ineffective for the audience and purpose
- little or no evidence of appropriate style
Elaborative techniques may include the use of personal experiences that support the opinion.
3 Conventions
The response demonstrates an adequate command of conventions:
- adequate use of correct sentence formation, punctuation, capitalization, grammar usage, and spelling
The response demonstrates a partial command of conventions:
- limited use of correct sentence formation, punctuation, capitalization, grammar usage, and spelling
The response demonstrates little or no command of conventions:
- infrequent use of correct sentence formation, punctuation, capitalization, grammar usage, and spelling
Holistic scoring considers Variety (range of error types), Severity (basic errors weighted more heavily than higher-level errors), and Density (proportion of errors to amount of writing done well).
How to score with the SBAC Opinion Performance Task 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.
Three-trait analytic, scored independently
- Score Organization/Purpose (1 to 4) and Evidence/Elaboration (1 to 4), then Conventions (0 to 2). Sum for the rubric total out of 10.
- Each trait is scored independently. A response can earn 4 on Organization but 1 on Evidence, or vice versa.
- Conventions uses a tighter 3-point scale (0, 1, 2).
Opinion writing, not argument
- Grades 3-5 students write OPINION responses, not Argumentative responses. The genre cue on the rubric is 'opinion,' not 'claim.'
- Counterarguments are not expected at this grade band. They appear on the Grades 6-11 Argumentative rubric starting at Grade 7.
- Strong opinion responses state a clear opinion in the intro, support with reasons and evidence, and conclude by restating the opinion.
Holistic Conventions scoring
- Variety: count error types across sentence formation, punctuation, capitalization, grammar usage, and spelling.
- Severity: basic errors weigh more than higher-level errors.
- Density: the ratio of errors to length. A short response with two errors may score lower than a long response with five errors of the same severity.
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, especially across genres.
Notes for the SBAC Opinion Performance Task Rubric, Grades 3–5
The SBAC Opinion rubric is the elementary-level analog of the Argumentative rubric used at Grades 6-11. Both rubrics share the same three-trait structure (Organization/Purpose 1-4, Evidence/Elaboration 1-4, Conventions 0-2), but the Grades 3-5 version uses 'opinion' as the genre cue and does not include any counterargument expectation.
Strong opinion responses are organized around a clear stance, supported by reasons drawn from the source material, and conclude in a way that restates or reinforces the opinion. Personal experience may be used as an elaborative technique where it supports the opinion.
Evidence/Elaboration rewards source integration with citations or attribution. At Grades 3-5, attribution can be informal ('the article says...') rather than formal citation.
Conventions is scored holistically using Variety, Severity, and Density. The descriptors are identical across all SBAC writing rubrics.

Why elementary schools should have longer recess
At my school, recess is only twenty minutes. I think elementary schools should have longer recess because kids need exercise, recess helps us focus in class, and the article shows that other schools have made it longer with good results.
Kids need more exercise
The article says that kids ages 6 to 10 should get at least one hour of physical activity every day. Twenty minutes of recess is not enough to count toward that hour, especially because we spend part of recess putting on jackets and waiting in line. A longer recess would give us real time to run around.
Recess helps us focus
The article also reports that a school in Texas tried 45 minutes of recess and saw students pay more attention in class afterward. Teachers said kids were less wiggly and got more work done. I have noticed the same thing on days when we get extra recess. Coming back to class is easier when I have used some of my energy.
Other schools have done it
The article describes three different schools that switched to longer recess. All three said grades did not drop and attendance got better. If those schools can fit longer recess into the day, my school can too.
Conclusion
Longer recess gives kids the exercise we need, helps us focus when we are back in class, and has worked at other schools. Elementary schools should make recess at least 45 minutes.
Clear opinion, three reasons each in its own paragraph
Opinion is stated in the intro and maintained throughout. Three reasons each get their own body paragraph with transitions. Conclusion restates the opinion clearly. Organization is fully sustained between and within paragraphs at the grade-appropriate level.
Adequate source integration with attribution
Evidence drawn from the article in all three body paragraphs with informal attribution ("The article says..."). Texas school example is specific. The first reason cites a stat (one hour of activity) but does not name the source as precisely. Vocabulary is grade-appropriate.
Adequate command of conventions
Sentence formation, punctuation, capitalization, grammar usage, and spelling are accurate throughout. Few errors and none impact clarity. Earns full credit on the 0-2 Conventions sub-scale.
