What this rubric measures
The IAR Research Simulation and Literary Analysis Writing Rubric, Grades 4–5 is the official scoring guide used to evaluate student writing on Illinois IAR 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 Illinois State Board of Education IAR scoring guide.
1 Reading Comprehension and Written Expression
The student response:
- demonstrates full comprehension of ideas stated explicitly and/or inferentially by providing an accurate analysis;
- addresses the prompt and provides effective development of the topic that is consistently appropriate to task, purpose, and audience;
- uses clear reasoning supported by relevant, text-based evidence in the development of the topic;
- is effectively organized with clear and coherent writing;
- uses language effectively to clarify ideas.
The student response:
- demonstrates comprehension of ideas stated explicitly and/or inferentially by providing a mostly accurate analysis;
- addresses the prompt and provides mostly effective development of the topic that is appropriate to task, purpose, and audience;
- uses mostly clear reasoning supported by relevant text-based evidence in the development of the topic;
- is organized with mostly clear and coherent writing;
- uses language that is mostly effective to clarify ideas.
The student response:
- demonstrates basic comprehension of ideas stated explicitly and/or inferentially by providing a generally accurate analysis;
- addresses the prompt and provides some development of the topic that is somewhat appropriate to task, purpose, and audience;
- uses some reasoning and text-based evidence in the development of the topic;
- demonstrates some organization with somewhat coherent writing;
- uses language to express ideas with some clarity.
The student response:
- demonstrates limited comprehension of ideas by providing a minimally accurate analysis;
- addresses the prompt and provides minimal development of the topic that is limited in its appropriateness to task, purpose, and audience;
- uses limited reasoning and text-based evidence;
- demonstrates limited organization and coherence;
- uses language to express ideas with limited clarity.
The student response:
- demonstrates no comprehension of ideas by providing an inaccurate or no analysis;
- is undeveloped and/or inappropriate to the task, purpose, and audience;
- includes little to no text-based evidence;
- lacks organization and coherence;
- does not use language to express ideas with clarity.
At Grades 4 and 5, the Reading Comprehension and Written Expression construct opens at score point 4 and includes a separate fully effective descriptor that does not exist at Grade 3. Knowledge of Language and Conventions remains on the 0 to 3 scale.
2 Knowledge of Language and Conventions
The student response to the prompt demonstrates full command of the conventions of standard English at an appropriate level of complexity. There may be a few minor errors in mechanics, grammar, and usage, but meaning is clear.
The student response to the prompt demonstrates some command of the conventions of standard English at an appropriate level of complexity. There may be errors in mechanics, grammar, and usage that occasionally impede understanding, but the meaning is generally clear.
The student response to the prompt demonstrates limited command of the conventions of standard English at an appropriate level of complexity. There may be errors in mechanics, grammar, and usage that often impede understanding.
The student response to the prompt does not demonstrate command of the conventions of standard English at the appropriate level of complexity. Frequent and varied errors in mechanics, grammar, and usage impede understanding.
Knowledge of Language and Conventions opens at score point 3 at Grades 4 and 5. There is no score 4 on this construct.
How to score with the IAR Research Simulation and Literary Analysis Writing Rubric, Grades 4–5.
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.
Asymmetric scales between constructs
- Reading Comprehension and Written Expression is scored 0 to 4 (5 points). Knowledge of Language and Conventions is scored 0 to 3 (4 points). Maximum is 7.
- The two constructs are scored independently. A response can earn 4 on Reading Comprehension and Written Expression and 1 on Conventions, or vice versa.
- Unlike Texas STAAR, IAR does NOT zero out Conventions when the first construct scores 0.
Five elements folded into the first construct
- Reading Comprehension and Written Expression folds five elements into one construct, comprehension accuracy (explicit and inferential), appropriateness to task and audience, reasoning supported by text-based evidence, organization and coherence, and language use.
- To earn a 4, the response must satisfy all five elements at the top descriptor level. A strong response that lacks text-based evidence typically caps at 3.
- Start at the lowest score point and ask, does the response meet all five elements at this level? Move up only when it clearly does.
Common pitfalls to avoid
- Awarding a 4 to a response with strong reasoning but no text-based evidence. Text-based evidence is one of the five required elements.
- Confusing accurate analysis with thorough analysis. A short, accurate analysis can earn 4; a long, partially accurate analysis caps at 3.
- Forgetting that Knowledge of Language and Conventions tops out at 3, not 4. The first construct uses a 5-point scale, the second uses a 4-point scale.
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 construct where graders are more than one point apart.
- Re-norm halfway through a long batch. Drift is real.
Notes for the IAR RST/LAT Rubric, Grades 4–5
At Grades 4 and 5, IAR introduces inferential comprehension to the rubric language. The score 4 descriptor explicitly requires accurate analysis of ideas stated explicitly and/or inferentially. A response that handles only explicit comprehension typically caps at 3.
RST and LAT prompts at Grades 4 and 5 typically pair source texts with an analytical writing prompt. RST uses informational sources; LAT uses literary sources. The scoring rubric is identical for both.
Knowledge of Language and Conventions still tops out at 3 at this grade band. The asymmetric scale (RC/WE 0 to 4, KLC 0 to 3) is intentional and matches PARCC's original framework.
If a response cannot be scored against the rubric (no response, unintelligible, not in English, off-topic, refusal, or do not understand), ISBE assigns a condition code (A through F) instead of a numeric score.

How Wilma Rudolph turned challenges into Olympic gold
Wilma Rudolph faced challenges as a child that many people would have given up over, but those same challenges built the strength she used to win three Olympic gold medals. Her story shows that early struggles can become a foundation for later success.
Polio and the doctors who said she would never walk
The article explains that when Wilma was four years old, she got polio. Doctors told her family that she would never walk normally again. Her mother refused to accept that, and they began a long routine of physical therapy four times a week. The article says it took six years before Wilma could walk without leg braces. Most kids would have stopped trying long before then.
A family that believed in her
Wilma was the 20th of 22 children, but the article describes how her family took turns rubbing her affected leg every day. This support taught her two things, that her family believed she could recover, and that recovery would take work. By the time she could finally run, she had learned a level of patience and discipline most young athletes never develop.
Turning recovery into gold
The article ends with Wilma at the 1960 Rome Olympics, winning three gold medals in track and field. She was the first American woman to do so. The connection between her childhood and her victories is clear: the same effort that helped her walk again is what made her run faster than anyone else. Without polio, the article suggests, there might not have been an Olympic Wilma Rudolph at all.
Full comprehension, effective development, strong text evidence
Accurate analysis of how challenges shaped success, with both explicit (six years of therapy, three gold medals) and inferential reasoning (patience and discipline transferred to athletics). Organized in three coherent body sections each tied to the thesis. Language is precise.
Full command at the grade 5 level
Sentence formation, punctuation, capitalization, and spelling are accurate. A few minor errors do not impede meaning. Meets the grade 5 standard for full command on the IAR Knowledge of Language and Conventions construct.
