The conclusion is the part students treat as an afterthought, and it is the part readers remember. It should not introduce anything new — but it should do more than summarise.
This guide gives you a repeatable structure, shows the difference between a weak and a strong conclusion, and explains how to end without padding.
What a Conclusion Should Do
- 1.Return to the argument in new wording — not a copy of your thesis sentence.
- 2.Pull together the reasoning that got you there, briefly.
- 3.Show significance: what follows if your position is right.
- 4.Optionally close with a recommendation or a remaining question.
Three to five sentences is usually right for a standard essay. Longer conclusions are common in dissertations, where you may summarise findings chapter by chapter.
Restate, Do Not Repeat
Restating your thesis word for word tells the reader nothing. Change the wording and sharpen the claim as you close — you have now earned the right to state it more precisely than you could at the start.
Example
Introduction: "This essay argues that remote work improves junior progression."
Weak conclusion: "To conclude, this essay has argued that remote work improves junior progression."
Strong conclusion: "The evidence therefore points in the opposite direction from common assumption: flexibility gains do not translate into progression, because visibility, not hours, drives early promotion."
Showing Significance
The most common weakness is a conclusion that stops at summary. One sentence on why the argument matters lifts the whole essay.
- Policy or practice: "Universities adopting this approach should pair it with X, or the effect will be uneven."
- Practical consequence: "For institutions, this means capacity planning must anticipate Y."
- Limits of your own argument: "This does not explain Z, which remains open."
What to Leave Out
- New evidence or sources introduced here.
- New counter-arguments you have not developed.
- New topics ("this essay has also explored...").
- Generic grand statements, rhetorical questions, and "in conclusion" openings.
- Apologies ("I know this is not perfect, but...").
A Structure You Can Reuse
Five-sentence conclusion
1. Restate the argument, sharpened. (Not identical to your thesis.)
2. Name the strongest reason that supports it.
3. Acknowledge the main counter-argument and why it does not change your position.
4. State the significance or implication.
5. Optional closing line: a recommendation, or the question that remains.
