What this rubric measures
The OST Holistic Opinion Writing Rubric, Grades 3–5 is the official scoring guide used to evaluate student writing on Ohio State Test (OST) assessments. It is an Holistic rubric that scores responses across 3 distinct criteria, allowing teachers to give precise, targeted feedback on each area of writing.
All 3 scoring criteria
Click any criterion to expand its score level descriptors. The language below is taken verbatim from the official Ohio Department of Education State Test (OST) scoring guide.
1 Purpose, Focus, and Organization
The response is exemplary and reflects original writing throughout that directly addresses the topic. It has a clearly stated opinion and is focused on the audience and purpose of the task. The organizational structure creates clarity and completeness. The response includes most of the following:
- an opinion that is strongly maintained throughout,
- little, if any, loosely related material,
- a clearly evident organizational structure that includes a skillfully crafted introduction and conclusion, and
- a logical progression of ideas that reflects a skillful use of transitional strategies to move from one idea to another.
The response is adequate and reflects original writing that reasonably addresses the topic. It has an opinion and is generally focused on the audience and purpose of the task. The organizational structure adequately reflects a sense of completeness. The response includes most of the following:
- an opinion that is evident throughout,
- some loosely related material,
- an adequate organizational structure that includes an introduction and conclusion, and
- a progression of ideas that includes basic transitional strategies to move from one idea to another.
The response is limited and reflects some original writing that is related to the topic. It has an opinion that is partially focused on the audience and purpose of the task. The organizational structure is inconsistent. The response includes most of the following:
- a limited opinion that is unclear or insufficiently sustained throughout,
- some loosely related material,
- an inconsistent organizational structure that has little or no evidence of an introduction or conclusion, and
- an uneven progression of ideas with an inconsistent use of transitions.
The response is minimal and reflects little original writing that may be loosely related to the topic. It reflects little awareness of the audience or purpose of the task. There is a minimally constructed opinion with little or no obvious organizational structure. The response may include the following:
- a minimal opinion that may be confusing or ambiguous,
- loosely or unrelated material,
- little or no evidence of an organizational structure, and
- ideas that are minimally related to the topic with few transitions and little or no progression.
Conventions opens at score point 2 on the OST rubrics, and a score of 0 is reserved for responses with frequent and severe errors. Purpose/Focus/Organization and Evidence/Elaboration both open at score point 4, with no descriptor at score 0 for those dimensions.
2 Evidence and Elaboration
The response is exemplary and includes thorough and convincing evidence that is directly related to the purpose of the task. It includes relevant evidence, facts, and details from all sources, as appropriate. Elaboration of evidence is focused, original writing and is clearly connected to the writer's opinion. The response includes most of the following:
- strong evidence from all sources that is well integrated throughout, directly related to the task, and references the source,
- clear connections between points and evidence,
- effective uses of a variety of relevant elaborative techniques (including but not limited to definitions, quotations, and examples), and
- the use of precise academic and domain-specific vocabulary that is clearly appropriate for the task.
The response is adequate and includes support and evidence that are related to the purpose of the task. It includes the use of evidence, facts, and details that are from all sources, as appropriate, and is generally connected to the writer's opinion. Elaboration of evidence is original writing but may be generalized. The response includes most of the following:
- evidence from the sources that may not be specific but is generally integrated into the response and includes some reference to the sources,
- adequate connections between points and evidence
- adequate elaboration on the evidence included, and
- academic and domain-specific vocabulary that is generally appropriate for the audience and purpose.
The response is limited and includes uneven, cursory support and text evidence related to the writer's opinion and the purpose of the task. There is an ineffective use of sources, facts, and details. Elaboration includes limited original writing. The response includes most of the following:
- weakly integrated evidence from sources that may be erratic and may include some irrelevant references,
- repetitive or ineffective use of elaborative techniques, and
- limited or ineffective academic or domain-specific vocabulary.
The response is minimal and includes little or no support or evidence related to the writer's opinion and the purpose of the task. There is little or no use of the sources and minimal inclusion of facts and details. The response may include the following:
- minimal, absent, erroneous, or irrelevant evidence or references from the source material,
- elaboration that has no original writing, is vague, lacks clarity, or is confusing, and
- minimal or inappropriate academic or domain-specific vocabulary.
Evidence and Elaboration does not include a score 0 descriptor. A response that fails to develop ideas at all collapses to score 1 (minimal) on this dimension.
3 Conventions
The response demonstrates and adequate command of basic conventions. The response includes most of the following:
- a few minor errors in usage, but no patterns of errors,
- variation of sentence structure, and
- an adequate use of punctuation, capitalization, sentence formation, and spelling.
The response demonstrates a partial command of basic conventions. The response may include the following:
- various errors in usage,
- simple sentence structures that do not vary, and
- an inconsistent use of correct punctuation, capitalization, sentence formation, and spelling that minimally impacts meaning.
The response demonstrates a lack of command of conventions, with frequent and severe errors often obscuring meaning.
The Conventions descriptor is identical across all four OST writing rubrics, the same 0 to 2 scale applies to Opinion, Informative/Explanatory (3 to 5), Argumentation (6 to HS), and Informational (6 to HS).
How to score with the OST Holistic 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.
Three-dimension holistic, scored independently
- Score Purpose, Focus, and Organization (1 to 4) and Evidence and Elaboration (1 to 4), then Conventions (0 to 2). Sum for the rubric total out of 10.
- Each dimension is scored independently. A response can earn 4 on Purpose/Focus/Organization but only 2 on Evidence/Elaboration, or vice versa.
- Unlike Texas STAAR, OST does NOT zero out other dimensions when one scores 0.
Read each dimension as a paragraph descriptor
- OST rubrics are described as holistic, the dimension descriptor at each score point reads as a paragraph, not as a checklist of independent criteria. Bulleted sub-elements describe what a response at that score point includes most of.
- Apply the descriptor that best fits the response as a whole on that dimension. A response does not need to hit every bullet to earn the score.
- Start at the top descriptor and work down until the bullets match the response. Move up only when the higher descriptor clearly fits.
Common pitfalls to avoid
- Treating Opinion as Argumentation. At Grades 3 to 5, students state an opinion and support it; they do NOT need to address opposing claims. That requirement appears at Grade 7 on the Argumentation rubric.
- Penalizing students for using only one source. The rubric uses the phrase from all sources, as appropriate. If the prompt provides one source, evidence from one source can earn the top score.
- Awarding score 4 to a response with a strong opinion but loosely related elaboration. Score 4 requires evidence clearly connected to the opinion.
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 dimension where graders are more than one point apart.
- Re-norm halfway through a long batch. Drift is real.
Notes for the OST Holistic Opinion Writing Rubric, Grades 3–5
The OST Grades 3 to 5 Opinion rubric is the elementary-grade opinion-writing rubric for the Ohio State Test ELA assessment. It uses the same 3-dimension structure shared across all four OST writing rubrics. The differences from the Informative/Explanatory Grades 3 to 5 rubric are mostly cosmetic, opinion replaces topic in the descriptor.
Source use is expected. Even at the elementary grade band, evidence is the second dimension and a response without source-based evidence typically caps at 2 on Evidence and Elaboration. If the prompt provides one source, evidence drawn from that one source can satisfy the from all sources, as appropriate phrasing.
Conventions on OST is identical across all four rubrics. The 0 to 2 scale rewards adequate basic conventions at score 2, partial command at score 1, and lack of command at score 0. Score 0 is reserved for frequent and severe errors that obscure meaning, not for occasional mistakes.
OST applies condition codes (which receive no points) to responses that cannot be scored against the rubric. Examples include blank responses, responses written off-topic, and responses written in a language other than English.

Why every elementary school should have recess every day
Elementary schools should have recess every day because recess helps kids focus better in class, lets them get exercise, and gives them a chance to make friends. The article gives strong reasons why daily recess is important, and I agree with all of them.
Recess helps us focus
The article says that doctors studied kids who had recess every day and kids who only had recess sometimes. The kids with daily recess could focus longer on hard work in the afternoon. When I go outside at lunch, I feel better when I come back inside. My brain feels ready to learn again. The article explains why, exercise helps blood reach the brain.
Recess gives us exercise
The article also says that many kids do not get enough exercise outside of school. Recess might be the only time some kids get to run around. Without recess, those kids would just sit all day. That is not good for our bodies or our learning. Daily recess makes sure every kid gets some exercise.
Recess helps us make friends
The article describes how kids on a playground learn to share, take turns, and solve problems together. My best friend and I met during recess in second grade. If we did not have recess, we might never have talked. Friends help us feel happy at school, and recess is where many friendships start.
Conclusion
Recess helps us focus, gives us exercise, and helps us make friends. The article shows that daily recess makes elementary schools better places to learn. Every elementary school should have recess every day.
Clearly stated opinion, evident organizational structure
Opinion is clearly stated in the intro and maintained throughout. Three reasons each have their own paragraph with topic sentences and transitions. Introduction and conclusion are crafted. Logical progression of ideas reflects skillful use of transitional strategies.
Adequate evidence, generalized elaboration
Evidence drawn from the article (focus study, exercise data, playground social skills) integrated with reference. Elaboration is original but uses personal examples (best friend story) where source-specific evidence would lift to a 4.
Adequate command of basic conventions
Sentence structure varies, punctuation, capitalization, and spelling are accurate, and minor errors do not pattern. Meets the score 2 descriptor on the OST Conventions dimension.
