Free AI STAAR ECR grader for teachers. Score Grades 3–8 RLA and EOC English I–II Extended Constructed Response essays in English and Spanish, against the official TEA rubric.
The full essay on every Texas STAAR Reading Language Arts test in Grades 3–8 and EOC English I & II, scored on a 0–5 rubric.
The STAAR ECR (Extended Constructed Response) is the full-essay portion of the Texas STAAR Reading Language Arts (RLA) assessment. It appears on every STAAR RLA test in Grades 3–8 and on the End-of-Course (EOC) English I and English II exams, and is graded with a dedicated STAAR ECR rubric.
Students read one or more passages, then write a complete essay (informational, argumentative, or correspondence in Grades 6+) that cites evidence from the text. Responses are capped at 2,300 characters, not counting spaces, which is roughly a 4–5 paragraph essay.
Each ECR is scored on a 5-point scale: Organization & Development of Ideas (0–3) plus Conventions (0–2). Since 2022–23, TEA first uses an automated scoring engine; responses that fall below a confidence threshold are then reviewed by human scorers. Two scorers each assign a 0–5 score; if they disagree by more than 1 point, a third scorer is added. The final reported score is still on a 0–5 scale.
Two components decide the score: Organization & Development of Ideas (0–3 points) measures thesis, structure, and use of text evidence; Conventions (0–2 points) measures grammar, spelling, and punctuation. Together they add up to the 0–5 STAAR ECR score.
Organization & Development of Ideas (0–3)
Score
What it means
3
Clear central idea or thesis; purposeful structure with effective introduction and conclusion; specific, relevant text evidence; logical flow; clear, effective expression.
2
Central idea is present but not fully focused; organization is uneven; evidence is limited or partly irrelevant; expression has gaps.
1
Weak or undeveloped central idea; minimal or confusing organization; insufficient or off-topic evidence; unclear or choppy expression.
0
Severely underdeveloped; no coherent structure; little or no relevant evidence; response is incoherent or completely off-topic.
Conventions (0–2)
Score
What it means
2
Strong command of grade-level spelling, punctuation, capitalization, sentence structure, and grammar. Errors are minor and do not interfere with meaning.
1
Inconsistent command. Several errors in spelling, punctuation, or grammar, but meaning is still generally understandable.
0
Little or no command of conventions. Frequent errors that make the response hard to read or that heavily obscure meaning.
The 0-cap rule: if a response receives a 0 in Organization & Development of Ideas, Conventions is automatically 0, even if grammar and spelling are clean. An off-topic or incoherent response cannot earn convention points.
Six illustrative excerpts at each scoring band on the STAAR 0–5 scale, with the rubric reasoning that drives the score. (Excerpts are illustrative, not real student work.)
The author shows that travel helps teenagers grow because it builds independence and broadens their perspective. In paragraph 4, the narrator says, "I had to figure out the train alone for the first time," which proves she became more self-reliant. Another reason is that travel exposes teens to new cultures. As the author notes, "every meal felt like a small classroom." Because of these reasons, schools should encourage student travel.
Why this score: Clear thesis, two reasons each backed by a direct quote with explanation, transition phrases, and a conclusion that closes the loop. Conventions are clean.
Travel helps teens grow alot. The author says travel makes you "self-reliant" and that means you can take care of yourself. it also lets you see new cultures like when she eats new food. So traveling is good for teenagers and schools should let them go on more trips.
Why this score: Solid central claim and two pieces of evidence with explanation, but spelling ("alot") and capitalization errors pull Conventions down to 1.
Travel is important for teens. They learn things and meet people. The story said travel was hard but good. teens should travel because its fun and you learn.
Why this score: Central idea is present but vague; evidence is paraphrased without specificity; multiple convention errors. Organization stays at 2 because there is a recognizable structure.
Argumentative essays are the most common. Top scores show clear claim, two strong reasons, an addressed counter-claim, and synthesis-level conclusions.
TEA publishes official Spanish-language STAAR ECR rubrics for Grades 3–5. CoGrader includes both.
Bilingual and dual-language teachers can grade Spanish ECR responses using the same scoring criteria the state uses: Desarrollo y Organización de las Ideas (0–3) and Convenciones (0–2).
CoGrader includes both Spanish ECR rubrics in the rubric library, so you can switch between English and Spanish grading without rewriting anything. Feedback is generated in the rubric's language.
What the strongest responses do at each paragraph, broken out by grade band.
Grades 3–5 (4-paragraph minimum)
Paragraph
Goal
What strong responses do
1. Introduction
Hook + clear topic/claim + roadmap.
One sentence naming the topic; one sentence previewing the two main reasons or pieces of evidence.
2. Body 1
Develop reason 1 with text evidence.
Topic sentence stating one reason; 1–2 short quotes or paraphrases; 1–2 sentences explaining how the evidence proves the reason.
3. Body 2
Develop reason 2 with text evidence.
Same pattern as Body 1 with a different reason and new evidence. Transitions like "Another reason…" boost organization.
4. Conclusion
Close the loop. Do not introduce new ideas.
Restate the main idea in a new way; briefly summarize the two reasons; end with a sentence that matches the prompt's tone.
Grades 6–English II (4–5 paragraphs, argumentative-friendly)
Paragraph
Goal
What strong responses do
1. Introduction
Clear thesis + claim + hint of evidence.
A clear claim (e.g., "The author argues that…") and a hint of the two main reasons or pieces of evidence to come.
2. Body 1
Reason 1 + evidence + explanation, sometimes a brief counter-answer.
Topic sentence; concrete example or quote; 2–3 sentences of explanation; in higher grades, a brief "Some might disagree…" then a push-back.
3. Body 2
Reason 2 + evidence + explanation.
Parallel to Body 1 with a different reason. Strong responses use evidence from both passages on paired-passage prompts.
4. (Optional) Body 3
Refine, broaden, or counter.
A third paragraph can address a counter-claim fully, add a third reason, or connect the idea to a broader theme.
5. Conclusion
Synthesize, do not just repeat.
Restate the thesis in new language; summarize the main reasons; end with a "big-picture" sentence that matches the prompt.

Frequently Asked Questions
Everything teachers ask about scoring the STAAR ECR.
What is a STAAR ECR?
The STAAR ECR (Extended Constructed Response) is a full essay students write on every Texas STAAR Reading Language Arts assessment in Grades 3–8 and on the End-of-Course (EOC) English I and English II exams. Responses are limited to 2,300 characters (not counting spaces) and are scored on a 5-point rubric.
How is the STAAR ECR scored?
The ECR uses a 5-point scale: Organization & Development of Ideas (0–3) plus Conventions (0–2). Two scorers each assign a 0–5 score; if they disagree by more than 1 point, a third scorer is added. The final reported score is still on a 0–5 scale.
What is a 5 on STAAR ECR?
A 5 is the highest possible score from a single scorer. It requires a 3 in Organization & Development (clear thesis, purposeful structure, specific text evidence, logical flow) and a 2 in Conventions (strong command of grade-level grammar, spelling, and punctuation, with only minor errors).
What is the 0-cap rule on the STAAR ECR rubric?
If a response receives a 0 in Organization & Development of Ideas, Conventions automatically becomes 0 as well, no matter how clean the writing is. The reasoning is that an off-topic or incoherent response cannot be meaningfully scored for conventions.
Is the STAAR ECR auto-graded?
Yes. Since 2022–2023, TEA uses an automated scoring engine as the first pass on STAAR ECR responses. Flagged responses (low confidence, unusual length, off-topic signals, or potential refusals) are routed to human scorers for review.
Does CoGrader use the same scoring as TEA?
CoGrader uses the official TEA ECR rubric for grading: Organization & Development of Ideas (0–3) and Conventions (0–2). Our AI is calibrated to match TEA rubric language, but CoGrader is a teacher-facing practice tool: you have full control to adjust any score before it is returned to students.
Does CoGrader grade STAAR ECR in Spanish?
Yes. CoGrader includes the official TEA Grades 3–5 Spanish Argumentative/Opinion and Informational rubrics. Bilingual and dual-language teachers can grade Spanish ECR responses against the same standards Texas uses.
What grades does the STAAR ECR cover?
Grades 3, 4, 5, 6, 7, 8 RLA and EOC English I and English II. Grades 3–5 use one rubric band; Grades 6 through English II share a slightly more demanding band with an extra "correspondence" genre option.
How long is a STAAR ECR response?
STAAR ECR responses are limited to 2,300 characters, not counting spaces. That works out to roughly 350–450 words depending on word length, enough room for a 4–5 paragraph essay.
What is the difference between STAAR ECR and SCR?
SCR (Short Constructed Response) is a brief paragraph-length answer to a specific question, scored on a 0–3 rubric. ECR (Extended Constructed Response) is a full essay scored on a 0–5 rubric. Both appear on the same RLA assessment, but the ECR carries more total points.
Can students use evidence from outside the passage on a STAAR ECR?
No. Strong ECR responses are text-based: every supporting reason should reference evidence from the assigned passage(s). Outside facts or personal opinions without textual support do not earn credit for evidence.
How many paragraphs should a STAAR ECR be?
Grades 3–5 typically aim for at least 4 paragraphs (intro, two body paragraphs, conclusion). Grades 6 through English II often use 4–5 paragraphs, with stronger responses adding an optional third body paragraph for counter-claim or synthesis.
How does CoGrader help students prepare for the STAAR ECR?
Teachers can run unlimited ECR practice rounds, get rubric-aligned feedback per student, and use class analytics to see which rubric criteria the class is weakest on. CoGrader integrates with Google Classroom, Canvas, Schoology, and DMAC.
Is CoGrader FERPA and SOC 2 compliant?
Yes. CoGrader is SOC 2 Type 1, FERPA, COPPA, and SOPIPA compliant, and follows the NIST 1.1 framework. Texas districts can review the full compliance pack on request.
What does it cost?
Individual teachers can use CoGrader free. Schools and districts get custom plans with admin controls, district-wide analytics, and LMS integrations. See pricing.
How does CoGrader compare to writing my own ChatGPT script?
A ChatGPT prompt can produce a number, but it does not give you per-criterion rubric reasoning, won't store class-wide analytics, won't round-trip with your gradebook, and is not FERPA-compliant. CoGrader is purpose-built for the STAAR ECR rubric and your classroom workflow.
Looking for the full Texas STAAR grading platform?
Beyond the STAAR ECR, CoGrader also grades SCRs, supports custom TEKS-aligned rubrics, and runs class-wide STAAR analytics.
