What this skill is asking
Analyzing the prompt is the step between reading the passages and writing the essay, and it decides whether your response answers the actual task. A long-composition prompt does two things: it sets a writing mode (argumentative, informative or explanatory, or a literary analysis of the passage) and it states the specific task, often with command words ("argue," "explain how," "analyze") and required parts ("use evidence from both passages," "address a central idea"). The skill students lose ground on is writing a strong essay that answers a slightly different question than the one asked, missing a required part, or writing in the wrong mode. This page covers identifying the mode, reading the command words and required parts, and turning the prompt into a plan. The transferable skill is treating the prompt as a contract: do exactly what it asks, all of it, and nothing it does not.
Identifying the writing mode
The first move is to name what kind of essay the prompt wants.
Reading the command words is the fastest way to fix the mode, because the verb tells you the move the prompt wants. "Argue whether" wants a side; "explain how" wants analysis of a method; "explain why" wants reasons. Matching your essay to the mode matters for the Idea Development trait, which rewards a response that does the task the prompt sets, not a well-written response to a different task. When in doubt, underline the command word and let it decide the kind of thesis you will write.
Reading the required parts
This is why prompt analysis is its own skill: a clear thesis and good evidence are wasted if they answer the wrong question or skip a required part. Turning the prompt into a checklist also gives you the skeleton of a plan, because each required part suggests a section of the essay. The same discipline of reading a task closely powers the reading items (where command words like "best," "most nearly," and "supports" tell you what to choose) and the argument-analysis skill, where you identify exactly what a claim must do. Read the prompt as a contract, and build the plan to fulfil all of it.
Turning the prompt into a plan
Try this
Q1. How do you tell whether a prompt wants an argument or an explanation? [Recall]
- Cue. Read the command word: "argue" or "take a position" calls for an argument; "explain," "analyze," or "explain how the author develops" calls for an explanatory or literary-analysis response.
Q2. A prompt reads: "Explain how the author uses the setting to develop the mood. Use details from the passage." Turn it into a checklist. [Short explanation]
- Cue. Parts: (1) mode is literary analysis ("explain how"); (2) focus on how the setting develops the mood, not on summarizing the plot; (3) use specific details from the passage as evidence. The plan should explain the setting-mood link and support it with text details.

Grade 10 ELA MCAS (style)1 marksA prompt says: 'Explain how the author develops the idea that change is difficult. Use evidence from the passage.' What writing mode does this call for? A. Argumentative (take a side). B. Literary analysis / explanatory (explain how the author develops an idea). C. A personal narrative. D. A description of a place.Show worked answer →
Answer: B. The command word "explain how the author develops" calls for analysis and explanation, not for taking a side. The task is to show how the writer builds the idea, using evidence from the passage, which is a literary-analysis or explanatory mode.
Why not the others: A would be signalled by "argue" or "take a position"; C and D ask for narrative or description, which this prompt does not. The command words tell you the mode, so read them first and write the kind of response they ask for.
Grade 10 ELA MCAS (style)2 marksDescribe how you would turn the prompt 'Argue whether the town should keep the old library, using evidence from both passages' into a plan.Show worked answer →
First, identify the mode: "argue whether" calls for an argumentative essay that takes a clear position. Second, read the required parts: take a side (keep or do not keep), and use evidence from both passages, so a plan that uses only one passage misses part of the task.
Then build the plan: a thesis stating the position, two or three reasons each supported by evidence drawn from the passages, and, for a strong argument, a brief response to the opposing view. The plan must cover every part the prompt names, the position and both passages, because answering the actual task is half the Idea Development score.
