What this topic is asking
Topic 4.3 (skill REO-1.A) asks you to write a conclusion suited to the rhetorical situation: one that closes the argument and extends it to its implications or significance. A conclusion is not a copy of the introduction. Its job is to leave the reader with the argument's meaning, why it matters beyond the page, which is also one of the best places on the exam to reach for the sophistication point.
What a conclusion does
The test of a conclusion is whether it adds. If you could delete it and lose nothing but a restated thesis, it has failed. A strong ending takes the reader one step further than the body did.
Extending beyond restatement
A brief return to the thesis can orient the reader, but the work of the conclusion is the extension. Reliable moves include:
- Implications. What follows if the argument is right? Who is affected, and how?
- Broader context. How does this issue connect to a larger principle, tension, or debate?
- Consequences. What happens if we act, or fail to act, on the argument?
- Call to action. A measured invitation to think or do something, suited to the audience.
Suiting the situation, staying efficient
Like the introduction, a conclusion should fit its rhetorical situation and stay lean. A reflective argument may end on a quiet image; a policy argument may end on a consequence or call to act. Either way, a tight, purposeful ending beats a long, repetitive one.
Why this matters for the exam
On the argument and synthesis essays, the conclusion is a prime site for the sophistication point, the hardest of the six, because explaining implications and significance is a named route to it. A strong ending also leaves the reader with the sense of a complete, controlled argument, which supports the reasoning band. On the rhetorical analysis essay, the same principles guide your own ending, and reading questions may ask what a conclusion accomplishes.
Try this
Q1. Name two moves, besides restating the thesis, that an effective conclusion can make. [Recall]
- Cue. Drawing out the implications of the argument (what follows if it is right, who is affected) and situating it in a broader context or principle. Other valid moves include naming consequences or issuing a measured call to action.
Q2. Why is the conclusion a good place to aim for the sophistication point? [Short explanation]
- Cue. Because the sophistication point rewards demonstrating a complex understanding, and explaining the implications of an argument or situating it in a broader context is a named route to that point. A conclusion that extends the argument outward to its significance does exactly the kind of thinking the point rewards, while also ending the essay.

AP 2024 (multiple choice, style)1 marksThe strongest conclusion to an argumentative essay most often does which of the following? (A) introduces a brand-new argument (B) extends the argument to its broader implications or significance (C) simply repeats the thesis in the same words (D) apologizes for the essay's limits (E) lists the sources used.Show worked answer →
Answer: (B). The skill is knowing what a conclusion should add.
A strong conclusion does more than restate: it reaches for the implications, the broader significance, or the consequences of the argument, leaving the reader with something to carry away.
Why not the others: (A) new arguments belong in the body, not the ending; (C) word-for-word repetition adds nothing; (D) apology undercuts the case; (E) a source list is not a conclusion.
Markers reward an ending that extends, rather than echoes, the argument.
AP 2021 (argument, style)6 marksCarefully consider the following idea: progress always carries a cost that is paid by someone. Then write an essay that argues your position on the idea, ending with a conclusion that extends your argument to its wider significance rather than merely restating it.Show worked answer →
Free Response Question 3 (argument), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication).
The prompt foregrounds the conclusion's job of extension.
Thesis (1 point): take a defensible position, e.g. "Progress does carry a cost, and a just society is one that chooses who pays it deliberately rather than by default."
Evidence and commentary (4 points): build the case in the body, so the conclusion has something to extend.
Sophistication (1 point): the conclusion is a prime place to earn it, by drawing out implications (who bears tomorrow's costs) or situating the argument in a broader tension.
The essay rewards a conclusion that opens outward to significance, exactly where the sophistication point often lives.
