What this rubric measures
The OST Holistic Argumentation Writing Rubric, Grades 6–HS 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 thesis statement, a clearly addressed alternate or opposing claim,* 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:
- a thesis statement that is strongly maintained throughout,
- little, if any, loosely related material,
- a clearly evident organizational structure that includes a skillfully crafted introduction and conclusion,
- a logical progression of ideas that reflects a skillful use of transitional strategies to move from one idea to another, and
- an appropriate style and an objective tone that are well established and maintained.
The response is adequate and reflects original writing that reasonably addresses the topic. It has a thesis statement and is generally focused on the audience and purpose of the task and includes a satisfactory alternate or opposing claim.* The organizational structure adequately reflects a sense of completeness. The response includes most of the following:
- a thesis statement 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 a thesis statement 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 thesis statement that is unclear or insufficiently sustained throughout,
- some loosely related material,
- insufficiently addressed alternate or opposing claims,
- 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 thesis statement with little or no obvious organizational structure. The response may include the following:
- a thesis statement that may be inadequate, confusing, or ambiguous,
- loosely related or unrelated material,
- little or no evidence of an organizational structure, and
- ideas minimally related to the topic with few transitions and little or no progression.
Per the ODE rubric, the alternate or opposing claim element is not applicable at grade 6. From Grade 7 onward, an addressed alternate or opposing claim is part of the score 4 and score 3 descriptors.
2 Evidence and Elaboration
The response is exemplary and includes thorough and convincing evidence that is directly related to the purpose of the task and references the source. 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 thesis statement. The response includes most of the following:
- strong evidence that is well integrated throughout, directly related to the task, and references the source,
- a clear relationship between points and evidence,
- effective use of a variety of 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/evidence that is related to the purpose of the task. It includes the use of evidence, facts, and details that are from all sources, as appropriate. It is generally connected to the thesis statement. 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 source,
- an adequate relationship 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 evidence related to a thesis statement and the purpose of the task. There is an ineffective use of sources, facts, and details. Elaboration contains 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 a thesis statement 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 text, is vague, lacks clarity, or is confusing, and
- inappropriate or ineffective 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 an 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
- 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
- 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.
How to score with the OST Holistic Argumentation Writing Rubric, Grades 6–HS.
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.
Counterargument expectations at Grade 7+
- The rubric is explicit, *not applicable at grade 6. From Grade 7 onward, the alternate or opposing claim is part of the score 4 and score 3 descriptors on Purpose/Focus/Organization.
- A clearly addressed alternate or opposing claim is required for score 4 at Grade 7 and above. A satisfactory alternate or opposing claim is required for score 3.
- At Grade 6, a focused, well-organized argument can earn 4 without addressing counterclaims, since the counterclaim element does not apply.
Common pitfalls to avoid
- Mistakenly applying the counterclaim requirement at Grade 6. The asterisk in the ODE rubric is explicit that the alternate or opposing claim element is not applicable at grade 6.
- Confusing thesis statement with topic sentence. Argumentation responses must take a defensible position, not just describe a topic.
- Awarding score 4 to a response with a strong thesis and counterclaim but generic vocabulary. The score 4 descriptor requires precise academic and domain-specific vocabulary.
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 Argumentation Writing Rubric, Grades 6–HS
The OST Argumentation rubric is the secondary-grade argumentative writing rubric for the Ohio State Test ELA assessment. It runs from Grade 6 through High School. The 3-dimension structure is identical to the other OST writing rubrics.
The most important grade-specific feature is the counterclaim asterisk. The Purpose, Focus, and Organization descriptor at scores 4 and 3 names a clearly addressed (or satisfactory) alternate or opposing claim, and the source PDF notes that this element is not applicable at grade 6. From Grade 7 onward, addressing the counterclaim is part of the descriptor.
Argumentation differs from Informational by introducing a thesis statement that takes a position. The score 4 descriptor also names appropriate style and objective tone that must be well established and maintained, language not present in the Informational rubric at the same grade band.
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 public libraries should expand evening hours
Public libraries were built around the rhythm of an industrial workday that no longer exists for most of the people who use them. Public libraries should expand their evening hours because doing so reaches users that current hours exclude, the additional cost is modest relative to the public benefit, and the most common objection (that demand is low) is contradicted by data from libraries that have already extended their hours.
Current hours exclude the people who most need library resources
Source 1, a usage study from the Ohio Library Council, reports that working adults and students who hold after-school jobs make up the fastest-growing demographic of patrons who report being unable to reach a branch before closing. The study finds that 38 percent of survey respondents who do not use their local library cite hours as the primary reason. The closing time, not the location, is the access barrier.
The additional cost is modest, the public benefit is not
Source 2, an operating-cost analysis from a regional library system, calculates that extending hours by 90 minutes per weekday raises the operating budget by roughly 6 percent. The same analysis projects an 18 to 24 percent increase in patron visits. A 6 percent cost increase that drives a 20 percent increase in use is, by any reasonable public-investment standard, a strong return.
Addressing the counterargument
Critics, including a quoted board member in Source 2, argue that evening expansion is unnecessary because branches are not full during current hours. This argument assumes that current demand reflects total demand, but Source 1 directly shows that 38 percent of non-users are excluded by hours, not by lack of interest. The supposed lack of demand is itself a function of when the library is open.
Conclusion
Public libraries serve the citizens who fund them, and current hours systematically exclude a significant share of those citizens. Modest investment in evening hours reaches the excluded users, generates measurable patron-visit gains, and dissolves the strongest objection on the table. The case for expansion holds across both sources.
Strongly maintained thesis, counterclaim addressed, objective tone
Thesis is stated in the intro and maintained throughout. Counterclaim is explicitly addressed using Source 1 data. Style is appropriate and objective tone is maintained.
Thorough, well-integrated evidence from both sources
Strong evidence from both sources (38 percent figure, cost-and-visit analysis) integrated with explicit attribution. Quoted material handled correctly. Effective elaboration.
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.
