Organization/PurposeHow clearly the essay states its thesis or controlling idea and how well its structure moves the explanation from introduction to conclusion.1–4 points

A clear, effective structure that feels unified and complete, with a consistent, purposeful focus.

  • The organization holds up between and within paragraphs.
  • The thesis or controlling idea is clearly communicated, and the focus stays strong for the purpose and audience.
  • A variety of transitions is used consistently to show how ideas relate to each other.
  • The introduction and conclusion are effective.
  • Ideas move logically from beginning to end, with strong links between them and some variety in sentence structure.

An evident structure and a sense of completeness; any flaws are minor and do not hurt overall coherence, and the response is generally focused.

  • The organization is adequately sustained between and within paragraphs.
  • The thesis or controlling idea is clear, and the focus is mostly held for the purpose and audience.
  • Transitions are adequate and show some variety.
  • The introduction and conclusion are adequate.
  • Ideas progress adequately, with adequate links between them.

An inconsistent structure with some evident flaws; some ideas are loosely connected and the focus may drift a little.

  • The organization is only somewhat sustained between and within paragraphs.
  • The thesis or controlling idea may be somewhat unclear, or the focus is not held well enough for the purpose and/or audience.
  • Transitions are used inconsistently or with little variety.
  • The introduction or conclusion, if there is one, may be weak.
  • Ideas progress unevenly or follow a formula, and the links between them may be inconsistent or unclear.

Little or no discernible structure; the response may relate to the topic but has little or no focus.

  • The thesis or controlling idea may be confusing or ambiguous, the response may be too brief, or the focus may shift away from the purpose or audience.
  • There are few or no transitions.
  • The introduction and/or conclusion may be missing.
  • Unrelated ideas show up often, and ideas may be in random order or hard to follow.
Not used for this criterion
Evidence/ElaborationHow well the essay develops its thesis or controlling idea with facts and details from the sources, credits them, and explains in precise language.1–4 points

Thorough elaboration of the evidence for the thesis or controlling idea, with effective use of the sources; ideas are developed clearly and in precise language.

  • Evidence (facts and details) from the sources is comprehensive, relevant and specific, and it is worked into the explanation.
  • Citations or attributions to the sources are clear.
  • A variety of elaboration techniques is used effectively.
  • Vocabulary clearly fits the audience and purpose.
  • An effective, appropriate style strengthens the content.

Adequate elaboration of the evidence for the thesis or controlling idea, with use of the sources and a mix of precise and more general language.

  • Evidence from the sources is relevant and integrated, but it may be general.
  • Citations or attributions to the sources are adequate.
  • Some elaboration techniques are used adequately.
  • Vocabulary is generally appropriate for the audience and purpose.
  • The style is generally appropriate.

Uneven, cursory elaboration with limited or uneven use of the sources; ideas are developed unevenly in simple language.

  • Some evidence from the sources is weakly integrated, imprecise, repetitive, vague or copied.
  • Citations or attributions to the sources are weak.
  • Elaboration techniques are weak or uneven; the development may be mostly a summary of the sources.
  • Vocabulary is uneven or somewhat ineffective for the audience and purpose.
  • The attempt at an appropriate style is inconsistent or weak.

Minimal elaboration with little or no use of the sources; the response is vague, unclear or confusing.

  • Evidence from the sources is minimal, irrelevant, missing, used incorrectly or mostly copied.
  • Citations or attributions to the sources are insufficient.
  • Elaboration techniques are minimal, if present.
  • Vocabulary is limited or ineffective for the audience and purpose.
  • There is little or no sign of an appropriate style.
Not used for this criterion
ConventionsCommand of sentence formation, punctuation, capitalization, grammar usage and spelling, scored as one holistic judgment.0–2 pointsNot used for this criterionNot used for this criterion

Adequate command of conventions.

  • Sentence formation, punctuation, capitalization, grammar usage and spelling are adequately correct for the length of the response.

Partial command of conventions.

  • Correct use of sentence formation, punctuation, capitalization, grammar usage and spelling is limited.

Little or no command of conventions.

  • Correct use of sentence formation, punctuation, capitalization, grammar usage and spelling is infrequent.

Total: 10 points (Organization/Purpose 4 + Evidence/Elaboration 4 + Conventions 2)

  • Each trait gets its own score: up to 4 + 4 + 2 rubric points. How the trait scores feed the Writing claim and scale score on a state report is set by the test's scoring rules, so the 10-point rubric total is a classroom number, not a scale score.
  • NS (no score) is separate from the score points. The two 4-point traits run from 4 down to 1; there is no 0 on those traits. Conventions runs 2, 1, 0.
  • Smarter Balanced notes that elaboration techniques can include personal experiences that support the controlling idea.
  • Conventions is scored holistically, not by counting errors. Scorers weigh variety (how many kinds of errors), severity (basic errors count more than errors in advanced constructions) and density (how many errors relative to the amount of writing, so length matters).
Not scored (no score point is given):
  • Insufficient: too little of the student's own writing to score, including a response that is mostly text copied from the sources or the prompt.
  • Written in a language other than English.
  • Off-topic: the response does not address the topic of the task.
  • Off-purpose: the response is on topic but written for a different purpose than the one asked for (for example, an opinion piece arguing a side when the task asks for an explanation). Organization/Purpose and the elaboration trait get NS; Conventions can still be scored, because off-purpose is not one of its NS conditions.

About the Smarter Balanced explanatory rubric

In an explanatory performance task, students research a topic through a short set of articles, videos or data, answer a few research questions, and then write an essay that explains something: how a process works, why something happens, or what a set of findings means. They are informing the reader, not taking a side.

That difference shapes the scoring. Where the argumentative rubric looks for a claim and counterarguments, this one looks for a thesis or controlling idea and for evidence that explains it. A student who slips into arguing a position can lose focus points, and a response written for an entirely different purpose is not scored.

Below are the three traits in plain language, a scored grade 7 sample, and the points where scorers most often disagree.

How to score with it

Organization/Purpose (1–4): one controlling idea, carried through

Find the thesis or controlling idea and check that it is a real statement about the topic ("Cities heat up because pavement and roofs store sunlight") and not just the topic restated ("This essay is about heat"). A 4 or 3 keeps every paragraph tied to it.

Look at how the explanation is ordered. Strong explanatory writing has a logic you can name: cause then effect, problem then solutions, general then specific. When paragraphs are in no particular order or end abruptly, the essay is a 2; when you cannot tell what it is trying to explain, it is a 1.

Evidence/Elaboration (1–4): facts that explain, not facts that pile up

The line between 3 and 2 is usually integration. A 3 essay uses relevant facts from the sources and says what they show. A 2 essay strings together facts or retells each source in turn, so the essay reads like a summary rather than an explanation.

For a 4, look for precision: exact figures, terms from the sources used correctly, definitions or examples that help a reader new to the topic, and sources named clearly. Copying long stretches of a source, or using facts that are wrong or off the point, belongs at 1.

Conventions (0–2): read the whole essay first

Score conventions once, after reading everything. Weigh how many kinds of errors there are, how basic they are and how dense they are for an essay of this length. A few slips earn a 2; repeated run-ons or sentence fragments that slow the reader suggest a 1.

When the essay argues instead of explains

A student who explains the topic but adds a strong opinion at the end is still on purpose; judge how much the opinion pulls focus. A response that is entirely a persuasive piece is off-purpose, which means NS on the first two traits while Conventions can still be scored.

Fictional sample · Grade 7

Prompt

Source summary (fictional, written by EasyClass): Students read three short sources about urban heat. "Hot Spots" explains that dark roads and roofs absorb sunlight and release heat at night, so a downtown can be up to 7°F warmer than nearby parks. "Shade on the Way" describes a city that planted 10,000 street trees and measured sidewalks up to 20°F cooler in the shade. A fact sheet explains that white or "cool" roofs reflect sunlight and can lower indoor temperatures. Task: Write an explanatory article for your school website that explains why cities get hotter than the areas around them and what can be done about it. Use the sources.

Have you ever noticed that downtown feels hotter than the park? This is called an urban heat island, cities get hotter than the land around them because of what they are built from, but there are ways to cool them down.

The main reason cities are hot is dark surfaces. According to "Hot Spots," roads and roofs soak up sunlight during the day and then they let the heat out at night. this is why a downtown can be up to 7 degrees warmer than a park. Parks have grass and trees so they dont store heat the same way.

One way to fix this is planting trees. In "Shade on the Way" a city planted 10,000 trees and the sidewalks in the shade where up to 20 degrees cooler. Trees block the sun before it hits the ground, its like putting an umbrella over the street.

Another way is cool roofs. The fact sheet says white roofs reflect sunlight instead of absorbing it. This makes buildings cooler inside so people use less air conditioning.

Cities are hot because of dark surfaces, but trees and cool roofs can help. If more cities try these ideas summers in the city could be a lot more comfortable.

Teacher tools for this rubric

A checklist to hand to students, comments you can reuse when you give feedback, and the mistakes that cost points most often.

Student checklist

  • I state my main idea about the topic in my introduction.
  • Each paragraph explains one part of my main idea.
  • I use specific facts, numbers or examples from the sources.
  • I name the source when I use its information.
  • I explain what each fact shows instead of just listing it.
  • I define words my reader might not know.
  • My conclusion sums up what I explained.
  • I check my sentences, punctuation and spelling.

Common mistakes

  • Scoring an explanatory essay as if it needs a counterclaim. That bullet belongs to the argumentative rubric only.
  • Rewarding an essay that summarizes each source in order. That is the rubric's description of uneven, cursory elaboration.
  • Accepting the topic as a thesis. "Urban heat" is a topic; a controlling idea says something about it.
  • Giving a 0 on a 4-point trait. Those traits go down to 1; a response below that is NS.
  • Marking down Evidence/Elaboration for spelling errors in quoted terms. Spelling belongs to Conventions.

Feedback comment bank

Organization/Purpose

  • 4 points

    Your controlling idea is clear and every paragraph builds on it. The order of your explanation makes the topic easy to follow.

  • 3 points

    Clear thesis and a sensible order. Strengthen the links between paragraphs so the reader sees how each part connects to the next.

  • 2 points

    I am not sure what your main idea is. Write one sentence that says what you are explaining, put it in your introduction, and check each paragraph against it.

Evidence/Elaboration

  • 4 points

    Precise, well-chosen evidence from several sources, clearly credited and explained. Your definitions help a reader new to the topic.

  • 3 points

    You use relevant facts from the sources. Add more precise details, like exact numbers, and explain what each one shows.

  • 2 points

    This reads more like a summary of each source. Choose the facts that explain your main idea and say how they connect.

Conventions

  • 2 points

    Your sentences are clear and errors are rare for an essay this long.

  • 1 point

    Several run-on sentences and mix-ups like its/it's make this hard to read in places. Proofread one paragraph at a time.

What differs from the official version
  • Descriptors are in EasyClass's own words. Trait names, score points, level order and the meaning of each bullet follow the Smarter Balanced rubric.
  • The NS (no score) conditions are listed separately instead of as a score of 0, matching the rubric's own layout.
  • The footnote on elaboration techniques and the holistic guidance for Conventions are summarized in the scoring notes.
Good to know
  • EasyClass is not affiliated with or endorsed by the Smarter Balanced Assessment Consortium or any state education agency.
  • Some state copies of this rubric in circulation (and an older EasyClass version) described Evidence/Elaboration in terms of a "claim and argument". The current Smarter Balanced explanatory rubric is written around a thesis or controlling idea, which is what this page follows.

Questions teachers ask

What is the difference between the explanatory and argumentative Smarter Balanced rubrics?

The traits and points are the same. The explanatory rubric asks for a thesis or controlling idea supported by facts from the sources. The argumentative rubric asks for a claim, reasoned analysis of evidence and, from grade 7, a response to opposing arguments.

Is "informational" the same as "explanatory" on Smarter Balanced?

They are the same purpose at different grade bands. Grades 3–5 use the Informational rubric; grades 6–11 use this Explanatory rubric. The structure is the same.

Can students use personal experience in an explanatory essay?

Yes, as one elaboration technique, if it supports the controlling idea. It does not replace evidence from the sources, which the rubric expects at every score above 1.

Why does an essay that is mostly quotes score low?

Copied or barely integrated source text is a sign of weak elaboration. If most of the response is copied, it can be marked insufficient and get no score.
