Organization and Development of Ideas · 3 points
3 points
Controlling idea/Thesis is clear and fully developed: clearly identifiable; focus is consistent throughout, creating a response that is unified and easy to follow. Organization is effective: purposeful structure with an effective introduction and conclusion; appropriate and effectively supports development of the controlling idea/thesis; sentences, paragraphs, or ideas logically connected in purposeful and highly effective ways. Evidence is specific, well chosen, and relevant: text-based, clearly explained, consistently supports and develops the controlling idea/thesis (for paired texts, evidence drawn from both texts); reflects a thorough understanding of the writing purpose. Expression of ideas is clear and effective: word choice is specific, purposeful, and enhances the response; almost all sentences and phrases are effectively crafted to convey the writer's ideas.
2 points
Controlling idea/Thesis is present and partially developed: presented but may not be clearly identifiable because it is not fully developed; focus may not always be consistent or easy to follow. Organization is limited: purposeful structure with introduction and conclusion present, but may not consistently support logical development; sentence-to-sentence connections and clarity may be lacking. Evidence is limited and may include some irrelevant information: text-based evidence may be insufficiently explained and/or irrelevant (for paired texts, drawn from at least one text); reflects partial understanding of the writing purpose. Expression of ideas is basic: word choice may be general and imprecise; sentences and phrases at times ineffective and may weaken the message.
1 point
Controlling idea/Thesis is evident but not developed: present but not developed appropriately for the task. Organization is minimal and/or weak: introduction or conclusion may be present; structure supporting logical development is not always evident or appropriate. Evidence is insufficient and/or mostly irrelevant: little text-based evidence, or mostly extraneous/repetitious; explanation is insufficient and vaguely related to the task (for paired texts, drawn from only one text); reflects a limited understanding of the writing purpose. Expression of ideas is ineffective: word choice is vague or limited; sentences and phrases often interfere with the writer's intended meaning.
0 points
A controlling idea/thesis may be evident. The response lacks an introduction and conclusion; an organizational structure is not evident. Evidence is not provided or is irrelevant; the response reflects a lack of understanding of the writing purpose. The expression of ideas is unclear and/or incoherent. (A score of 0 here automatically yields 0 on Conventions.)

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
Some districts have moved their middle school start times later in the morning. Write an essay arguing whether middle schools should start later. Support your position with specific reasons and examples.
My middle school starts at 7:40 in the morning, which means my alarm goes off at 6:05. Middle schools should push their start time back to at least 8:30, because students are not actually awake for first period, because the schedule works against how our bodies are built, and because it would help attendance1.
The clearest problem is that first period is wasted. My first class is science, which is the hardest class I have, and I spend most of it trying to keep my eyes open. Last month our teacher gave the same review quiz to our 7:40 class and to her fifth period class. Our class average was eleven points lower on the exact same quiz.2 That is not because we are worse at science. It is because we took it before our brains had started.3

How it scored, criterion by criterion
The essay opens with a clear, multi-part thesis and the first body paragraph supports it effectively with a concrete, specific example (the quiz score comparison). However, the second body paragraph abandons the argument mid-way — 'Our school has a really nice new gym that they built two years ago' is entirely irrelevant — and the promised reasons about biology and attendance are never meaningfully developed. The counterargument paragraph ('I know the main objection is buses. That would be hard to fix.') is acknowledged but not addressed, which weakens the overall development. The conclusion is present but thin.
The essay is largely clean: capitalization, spelling, and grammar are correct throughout. The final sentence is a comma splice ('Middle schools should start at 8:30, the research supports it and the test scores support it'), which is the only notable convention error and does not significantly impair clarity. This is consistent with a score of 2.
What the student was told to fix
- Develop every reason in the thesis — write a full paragraph on biology and a full paragraph on attendance, each with specific evidence
- Cut the irrelevant gym sentence and stay focused on start times in every paragraph
- Expand the counterargument: don't just name the objection, explain why the benefit outweighs the difficulty or propose a solution
