What this rubric measures
The ISASP Informative/Explanatory Writing Rubric, Grades 4–5 is the official scoring guide used to evaluate student writing on Iowa ISASP assessments. It is an Analytic rubric that scores responses across 4 distinct criteria, allowing teachers to give precise, targeted feedback on each area of writing.

1 Prompt Task
The response demonstrates the following:
- Provides a context for the explanation. Topic(s) and purpose of explanation are clear from the start. Successfully uses ample relevant evidence from provided texts to support the explanation.
The response demonstrates the following:
- Topic(s) and purpose of explanation are clear. Appropriately uses some evidence from provided texts to support the explanation.
The response demonstrates the following:
- Topic(s) and purpose of explanation are apparent within the response as a whole. Evidence from provided texts is used but is limited, overused, or misrepresented.
The response demonstrates the following:
- Topic(s) and purpose of explanation are unclear or otherwise confusing. Attempts to use evidence from provided texts are unsuccessful (text sections are lifted exactly, misunderstood, or not relevant to the ideas they are used in support of).
The response demonstrates the following:
- Topic(s) and purpose of explanation are never indicated. No attempt is made to use evidence from provided texts to support the explanation.
Grade 4 begins the Prompt Task descriptor at score 5 with 'Topic(s) and purpose of explanation are clear from the start.' Grade 5 prepends 'Provides a context for the explanation.' This page uses the Grade 5 wording as the canonical descriptor.
2 Development of Explanation
The response demonstrates the following:
- Explains topic(s) completely. Effectively uses ample specific and relevant facts, definitions, details, examples, and/or other appropriate information in the explanation.
The response demonstrates the following:
- Explains topic(s) adequately. Explanation includes some specific and relevant facts, definitions, details, examples, and/or other appropriate information.
The response demonstrates the following:
- Explains topic(s) to a limited extent or the explanation is developed unevenly. Explanation includes few or only general facts, details, and examples. Some information may be repetitious or may not be clearly relevant.
The response demonstrates the following:
- Explains topic(s) by providing some information but explanation is minimal and/or superficial, and parts may be repetitious or not relevant.
The response demonstrates the following:
- Development of topic(s) lacks explanation of ideas, only repeats ideas, or most ideas are not relevant. May demonstrate a lack of understanding of the purpose of explanatory writing.
3 Organization
The response demonstrates the following:
- Has a clear, well-developed introduction. Provides a logical concluding statement or section. Organizes ideas effectively, clearly grouping related ideas together throughout the response. Consistently uses varied linking words, phrases, and clauses to connect ideas.
The response demonstrates the following:
- Has a clear, somewhat developed introduction. Provides a clear concluding statement or section. Organizes ideas adequately, grouping related ideas together throughout the response. Consistently uses simple and/or repetitive linking words, phrases, and clauses to connect ideas.
The response demonstrates the following:
- Provides a basic introduction and basic concluding statement or section. Generally groups related ideas together, though parts of the response may be out of place. Sometimes uses linking words, phrases, and clauses to connect ideas.
The response demonstrates the following:
- Has minimal evidence of an introduction and/or a concluding statement or section. Groups a few related ideas together within the response but overall demonstrates weak organization skills. Use of linking words, phrases, and/or clauses to connect ideas lacks control and may cause confusion.
The response demonstrates the following:
- Lacks an introduction and a concluding statement or section. Demonstrates no understanding of organization (or response may be too short to assess). Does not use linking words, phrases, and/or clauses to connect ideas.
4 Language Use
The response demonstrates the following:

The response demonstrates the following:
- Uses mostly specific and somewhat varied word choice. Occasionally employs topic-specific vocabulary successfully. Demonstrates adequate control of sentences with some variety in length and structure.
The response demonstrates the following:
- Uses general word choice. Attempts to employ topic-specific vocabulary may be unsuccessful. Demonstrates a little variety in sentence structure, although there may be a few long, uncontrolled sentences.
The response demonstrates the following:
- Uses simple and/or repetitive word choice. Uses repetitive sentence structure and/or long, uncontrolled sentences.
The response demonstrates the following:
- Uses awkward, incorrect, and/or confusing word choice and sentence structure.
How to score with the ISASP Informative/Explanatory 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.
Four-trait analytic, scored independently
- Score each of the four traits (Prompt Task, Development, Organization, Language Use) on its own pass, then sum for the rubric total out of 20.
- Each trait uses the same 1 to 5 scale. A response can earn 5 on Development (rich specific facts) and 3 on Language Use (general word choice). Score independently.
- Start at the lowest score point and ask, does the response meet this descriptor? Move up only when it clearly meets the next level.
Informative-specific notes
- ISASP informative/explanatory prompts are source-based. The Prompt Task trait rewards evidence drawn from the provided text(s), not background knowledge.
- Topic-specific vocabulary is explicitly part of Language Use at this grade band. Reward responses that use words like 'habitat,' 'predator,' or 'photosynthesis' when the source introduces them, not just general words like 'place' or 'animal.'
- The genre is explanation, not argument. Penalize responses that take a position rather than explain a topic. Those should be scored under the opinion/argument rubric, not this one.
Common pitfalls to avoid
- Confusing 'topic-specific vocabulary' with long words. A 4th-grader using 'pollinator' correctly is hitting the descriptor; a sprinkling of unrelated SAT words is not.
- Awarding 5 on Development to a response with lots of facts but weak connections among them. The descriptor requires 'effectively uses' the information, not just listing it.
- Letting strong organization halo weak topic explanation. Organization and Development score independently.
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 when scoring topic-specific vocabulary.
Notes for the ISASP Informative/Explanatory Rubric, Grades 4–5
ISASP does not administer informative/explanatory writing at Grade 3. The genre enters at Grade 4. This page covers Grades 4 and 5, whose rubrics share nearly identical descriptor language.
The Grade 5 rubric prepends 'Provides a context for the explanation' to the score 5 Prompt Task descriptor. Grade 4 starts directly with 'Topic(s) and purpose of explanation are clear from the start.' This page uses the Grade 5 wording as the canonical descriptor.
Topic-specific vocabulary enters explicitly on the Language Use trait at this grade band, an expectation that distinguishes informative/explanatory from opinion or narrative writing.
All four traits are scored on the same 1 to 5 scale. The maximum total per rubric is 20 points.

How honeybees keep our farms growing
Most people think of honeybees as the small insects that make honey, but they do something even more important for farms. Honeybees are pollinators, which means they move pollen from one flower to another so that fruits and vegetables can grow. Without them, many of the foods we eat would become rare or much more expensive.
How pollination works
When a honeybee lands on a flower to drink nectar, pollen sticks to the tiny hairs on its body. The article explains that when the bee flies to the next flower, it brushes some of that pollen onto the new flower, which lets the plant make seeds and fruit. According to the article, honeybees pollinate about 130 different crops in the United States, including almonds, apples, and blueberries. One scientist in the article said that without honeybees, almond farms in California would not be able to produce a crop at all.
Why honeybees are at risk
The article describes several threats that honeybee colonies face. Pesticides used on crops can poison the bees, even when farmers do not mean to harm them. Diseases like Colony Collapse Disorder cause whole hives to die. Loss of wildflowers also means bees have fewer places to find nectar between farm fields. Together, these problems have made the number of healthy honeybee colonies smaller over the last twenty years.
How farmers help honeybees
Farmers across Iowa and other states are working to protect honeybees. Some plant strips of wildflowers along the edges of their fields so bees have food when the crops are not in bloom. Others use fewer pesticides or apply them at night when bees are not active. The article describes one Iowa farmer who started keeping his own beehives near his orchard and saw better apple crops within two years.
Conclusion
Honeybees are tiny, but they do a job that no machine can do for them. By moving pollen from flower to flower, they make it possible for farms to grow the fruits, nuts, and vegetables that fill our kitchens. Protecting honeybees is one of the most important things farms can do.
Clear topic, ample evidence from the source
Topic ("why honeybees are important to farms") is established in the intro. Evidence is drawn directly from the article (130 crops, almond farms, the Iowa farmer example, the Colony Collapse reference). Earns full credit on Prompt Task.
Specific facts well used, some general claims
The response explains pollination clearly with specific examples (almonds, the Iowa farmer's orchard). Some claims ("loss of wildflowers") are general where a 5 would name a specific cause. Topic vocabulary (pollinators, nectar, Colony Collapse Disorder) is used correctly.
Clear structure, simple transitions
Intro defines pollination, three body paragraphs handle how/why/help in logical order, conclusion ties back to the opening image. Transitions ("When a honeybee," "The article describes") are clear but simple.
