What this skill is asking
Every strong extended response is built on one sentence: a claim if the prompt asks for argumentation, or a controlling idea if it asks for informative or explanatory writing. This sentence is the spine of the essay. It answers the prompt directly, it tells the reader what the whole response will do, and on Ohio's State Test for English Language Arts II it is the heart of the Purpose, Focus, and Organization domain. A vague or missing claim drags every other part of the essay down, because the body has nothing clear to support. This page covers how to write a precise, defensible claim for an argument, how to write a clear controlling idea for an explanation, how to make sure the texts can actually support it, and where to put it so a reader finds it immediately. Getting this sentence right is the highest-leverage move in the whole module.
A claim for argumentation
When the prompt asks you to argue, your anchor sentence must take a side and be defensible from the passages.
The fastest way to test a claim is to ask whether someone could reasonably disagree and whether the passages give you the evidence to answer them. If no one could disagree, it is not really an argument; if the passages do not support it, you cannot defend it. A strong claim often previews the reasons you will develop, which doubles as a plan for the body. Argumentation at the English II level usually rewards acknowledging the other side, so a claim can be sharper when you know which opposing points you will answer, the same analysis you practice in analyzing argument and claims.
A controlling idea for informative writing
When the prompt asks you to explain or analyze, you do not take a side, but you still need a clear anchor.
The difference between a claim and a controlling idea is the difference between the two modes. A claim argues; a controlling idea explains. Both must answer the prompt directly and both must be supportable from the texts. Writing the wrong one for the mode, arguing a side when the prompt says explain, signals that you misread the task, which is why prompt analysis in analyzing the prompt and mode comes first.
Writing and placing the sentence
A claim or controlling idea earns its marks only if the reader can find it and the body delivers on it.
Try this
Q1. What is the difference between a claim and a controlling idea? [Recall]
- Cue. A claim takes a defensible position for an argumentation prompt; a controlling idea names and frames the idea an informative or explanatory essay develops, without taking a side. Both must answer the prompt and be supportable from the texts.
Q2. Turn this weak anchor into a strong one for an argumentation prompt about whether a school should require uniforms: "Uniforms are a topic people argue about." [Short explanation]
- Cue. A strong version takes a side and previews supportable reasons, for example: "The school should require uniforms because the passages show they reduce distraction and ease morning routines." It answers the prompt directly and points the body toward specific evidence.

Ohio English II EOC (style)1 marksAn argumentation prompt asks whether a city should build a new library. Which is the strongest claim? (1) Libraries are nice. (2) The city should build the new library because the passages show it would expand access and support local jobs. (3) This essay is about libraries. (4) Some people like libraries and some do not.Show worked answer →
Answer: (2). A strong claim takes a clear position (the city should build it) and previews the supportable reasons drawn from the texts (access and jobs). It tells the reader exactly what the essay will argue.
Option (1) is a vague opinion, not a position on the prompt; (3) announces the topic without a stance; (4) sits on the fence and commits to nothing. Under Purpose, Focus, and Organization, a reader rewards a claim that is precise, defensible, and clearly tied to the prompt.
Ohio English II EOC (style)1 marksFor an informative prompt asking you to explain how an author develops the idea that change is hard, which is the best controlling idea? (1) Change is hard. (2) The author develops the idea that change is hard through a reluctant character, a setback, and a final small step forward. (3) I will explain the passage. (4) The passage is interesting.Show worked answer →
Answer: (2). A controlling idea for an explanatory essay names the idea and previews how it is developed, giving the essay a clear frame the body can follow.
Option (1) merely repeats the prompt's topic; (3) describes what you will do without saying anything; (4) is an empty reaction. A controlling idea is not a claim to defend, but it must still be specific enough to organize the whole response.
