The IELTS essay conclusion is the final impression an examiner has of your essay — and while a strong conclusion alone won't save a weak essay, a poor conclusion can definitely damage a good one. Conclusion mistakes are specific and correctable, and many candidates who write strong body paragraphs undermine their Coherence score with an inadequate or structurally incorrect conclusion.
1Mistake 1: Introducing New Information
The most serious conclusion mistake: introducing new arguments, evidence, or examples that were not discussed in the body paragraphs. A conclusion is a summary and a restatement of position — not a place for new content. Why this is problematic: new information in a conclusion suggests the essay is not logically organised and that important points were not developed in the body. This reduces Coherence and Cohesion scoring. Fix: before writing your conclusion, list the two main ideas you developed in your body paragraphs. Your conclusion should only reference these two ideas — nothing else. If you find yourself adding something new in the conclusion, it should have been in a body paragraph.
2Mistake 2: Simply Repeating the Introduction
A conclusion that copies the introduction word for word (or near word for word) demonstrates no paraphrasing ability and feels mechanical. Example: Introduction: 'Government investment in public transportation is essential and should be substantially increased.' BAD Conclusion: 'Government investment in public transportation is essential and should be substantially increased.' Fix: paraphrase your thesis using different vocabulary and sentence structure, and include a brief summary of the supporting reasons from your body paragraphs: 'In conclusion, it is clear that directing public funds toward transportation infrastructure represents a vital policy priority, both for its documented environmental benefits and its role in reducing traffic congestion in urban centres.'
3Mistake 3: Missing the Conclusion Entirely
Some candidates, particularly those running short on time, omit the conclusion. Ending with the final body paragraph is a Coherence error — the essay lacks logical closure. Fix: always write the conclusion, even if time is limited. A one-sentence conclusion is better than no conclusion: 'In conclusion, while challenges exist, the benefits of increased public transportation investment clearly outweigh the costs.' This sentence is 23 words and takes less than 30 seconds to write — there is no scenario where time pressure justifies skipping it. Build the conclusion as a habitual final step in every practice essay.
4Mistake 4: Excessively Long Conclusions
Conclusions that extend to 100+ words often introduce new information (Mistake 1), go beyond summarising into detailed re-argumentation, or reduce time available for body paragraph development. Fix: target 40–60 words for the conclusion (2–3 sentences). Structure: Sentence 1: 'In conclusion, …' or 'To summarise, …' + thesis restatement (paraphrased). Sentence 2: Brief summary of the main supporting reasons. Optional Sentence 3: Broader reflection or recommendation. This structure is complete, effective, and achievable in under 2 minutes — leaving maximum time for the body paragraphs where marks are won.
🎯 Key Takeaway
A good IELTS conclusion is concise, paraphrased from the introduction, free of new information, and always present. The conclusion does not need to be impressive — it needs to be correct. A competent 50-word conclusion that summarises accurately is worth more than an ambitious 100-word conclusion that introduces new ideas.
