Organization and Development of Ideas · 3 points
3 points
Controlling idea/Thesis is clear and fully developed: The controlling idea/thesis is clearly identifiable. The focus is consistent throughout, creating a response that is unified and easy to follow. Organization is effective: A purposeful structure that includes an effective introduction and conclusion is evident. The organizational structure is appropriate and effectively supports the development of the controlling idea/thesis. The sentences, paragraphs, or ideas are logically connected in purposeful and highly effective ways. Evidence is specific, well chosen, and relevant: The response includes relevant text-based evidence that is clearly explained and consistently supports and develops the controlling idea/thesis. For pairs in grades 6 through EII, evidence is drawn from both texts. The response reflects a thorough understanding of the writing purpose. Expression of ideas is clear and effective: The writer's word choice is specific, purposeful, and enhances the response. Almost all sentences and phrases are effectively crafted to convey the writer's ideas and contribute to the overall quality of the response and the clarity of the message.
2 points
Controlling idea/Thesis is present and partially developed: A controlling idea/thesis is presented, but it may not be clearly identifiable because it is not fully developed. The focus may not always be consistent and may not always be easy to follow. Organization is limited: A purposeful structure that includes an introduction and conclusion is present. An organizational structure may not be consistent and may not always support the logical development of the controlling idea/thesis. Sentence-to-sentence connections and clarity may be lacking. Evidence is limited and may include some irrelevant information: The response may include text-based evidence to support the controlling idea/thesis, but it may be insufficiently explained, and/or some evidence may be irrelevant to the controlling idea/thesis. For pairs, evidence is drawn from at least one of the texts. The response reflects partial understanding of the writing purpose. Expression of ideas is basic: The writer's word choice may be general and imprecise and at times may not convey the writer's ideas clearly. Sentences and phrases are at times ineffective and may interfere with the writer's intended meaning and weaken the message.
1 point
Controlling idea/Thesis is evident but not developed: A controlling idea/thesis is present but not developed appropriately in response to the writing task. Organization is minimal and/or weak: An introduction or conclusion may be present. An organizational structure that supports logical development is not always evident or is not appropriate to the task. Evidence is insufficient and/or mostly irrelevant: Little text-based evidence is presented to support the controlling idea/thesis, or the evidence presented is mostly extraneous and/or repetitious. Explanation of any evidence presented is insufficient and may be only vaguely related to the writing task. For pairs in grades 6 through EII, evidence is drawn from only one text. The response reflects a limited understanding of the writing purpose. Expression of ideas is ineffective: The writer's word choice is vague or limited and may impede the quality and clarity of the essay. Sentences and phrases are often ineffective, interfere with the writer's intended meaning, and impact the strength and clarity of the message.
0 points

This rubric applied to a real essay
Below is a sample essay scored against the rubric above, shown the way it looks inside the grader. The marks, the scores and every comment are the grader’s own output, not written by hand for this page. It scored 4 out of 5.
The essay is written for this page, at roughly a B grade so both the strengths and the weaknesses are worth seeing. It is not a real student’s work.
The prompt
Write an essay explaining the role a public library plays in its community. Use specific examples to develop your explanation.
Most people think a public library is just a building full of books to borrow. Our town library does lend books, but the more time I spend there, the more I notice that lending books is only a small part of what it actually does for the people who live here1.
The library is one of the only indoor places in town where nobody has to buy anything to stay. On a weekday afternoon the study rooms are full of high school students who do not have a quiet place to work at home2, and the tables near the window are usually taken by adults using the free wifi. Our library has fourteen public computers, and when I asked, the librarian told me that the most common thing people use them for is filling out job applications. For someone without a computer at home, that is not a convenience. It is the only way to apply.3
The library also runs programs for people at both ends of their lives.4 There is a story hour for toddlers on Tuesday mornings, and a computer help session for older adults on Thursdays where volunteers show people how to use email or read a document their doctor sent them.5
All of this is paid for by the town, which means it belongs to everyone equally.7 A library card costs nothing and gives a person the same access whether they live in the biggest house in town or are staying with a relative. That is unusual, and it is worth protecting.8

How it scored, criterion by criterion
The essay has a clear controlling idea — that the library serves the community in ways far beyond lending books — and it holds that focus consistently. The introduction and conclusion both function purposefully, with the closing paragraph landing an effective point about equity. However, several body paragraphs are only partially developed: the paragraph about library programs gestures at examples without explaining their significance, and the paragraph about lending non-book items ('There are a lot of items available') collapses into a vague placeholder with no actual examples or explanation. Evidence is specific and well-chosen in the strongest sections (the fourteen computers, job applications, the wifi tables) but absent or irrelevant in others, leaving the overall development uneven and fitting the '2' level rather than '3'.
The essay is largely clean: sentences are correctly constructed, punctuation is handled well, capitalization is consistent, and there are no noticeable spelling errors. The few moments of awkwardness (such as mildly loose phrasing in places) do not impede clarity. This comfortably meets the top level for conventions.
What the student was told to fix
- Fully develop the 'lending non-book items' paragraph with real, named examples and explanation
- Add a sentence of significance/so-what after the programs paragraph's examples
- Strengthen the conclusion by calling back to specific evidence before the final line
- Where possible, ground claims with concrete numbers or sourced details as you did with the fourteen computers
