An essay has three parts, and each has one job: the introduction says what the essay will argue, the body proves it one point at a time, and the conclusion answers the question. This guide to how to structure an essay, published by EdCitation, takes each part in turn, with a worked outline of our own and the rough proportions universities actually publish.
Every rule here was read on 26 September 2026 at seven universities' writing centres and libraries: Kent, Swansea and Derby in the UK, Harvard and the University of North Carolina at Chapel Hill (UNC) in the US, Victoria University in Australia and Canterbury in New Zealand. They agree on the three parts and disagree on details, which we name.
EdCitation never writes any part of an essay. It reads your brief into a checklist with Check your paper, finds the evidence each paragraph needs with Find sources, and builds and checks the references with Cite a source and Verify references.
How to structure an essay, step by step
Plan before you draft.
- Read the brief for the question, word limit, sources and style. Check your paper reads them into a checklist, free, each shown with the sentence it came from.
- Write a one-sentence answer to the question: your working thesis.
- Break the thesis into the points it depends on, one point to a body paragraph.
- Order the points so that each needs only what came before it, and place the counterargument.
- Find evidence for each point. Find sources looks through about 300 million published works, searched by topic or by the exact claim a paragraph makes.
- Draft the body, then the conclusion, then the introduction.
- Make a reverse outline of the draft, one line per paragraph, and test the order.
- Check the references with Verify references, then the essay against its brief with Theoretics QA (Max).
What goes in an essay introduction?
An essay introduction gives enough context to understand the question, says what its key terms mean in this essay, states the thesis and, in many subjects, maps the order of the argument. University of Kent (2025) gives nearly the same list: the scene, the argument, the key theories, then a signpost of the order. Swansea University (n.d.) calls the result an "essay map", and the University of Canterbury Learning Skills Centre (n.d.) puts the thesis near the end of the introduction, often with a road map after it.
Context: the funnel, and why Harvard warns against it
The guides split here. Swansea recommends a "funnel" that moves from general context to key concepts to the thesis. Harvard College Writing Center (n.d.-d) says to avoid a funnel that starts from a broad statement about the topic, since a generalisation does not help the reader understand this essay. University of North Carolina at Chapel Hill Writing Center (n.d.-c) sits between them: context, but at the scale of the question, as you would zoom a map to a city rather than the globe, and never the "dawn of man" opening.
In our view they can be reconciled: give context, but let the first sentence already be about the question, and use the context, as Harvard asks, to show why the thesis is worth arguing.
Key terms: define the ones the question depends on
Swansea and Canterbury give definitions a place in the introduction; Canterbury suggests a separate paragraph of 150 to 200 words when there are many terms. Harvard and UNC both warn against opening with a dictionary definition. The advice fits together: define a term when the answer turns on its meaning, in the sense your course or sources use.
The thesis and the map
The thesis is the one-sentence answer to the question; it gets its own guide in this series. The map varies by subject. Kent and Swansea expect one; Harvard College Writing Center (n.d.-e) says only some courses expect a roadmap and its introductions page names Government and Economics as subjects where a preview is common. If the brief is silent, ask your tutor. UNC, Canterbury and Kent all suggest writing or rewriting the introduction last, so that it promises what the essay delivers.
How should body paragraphs be structured?
Each body paragraph makes one point, stated in a topic sentence near its start, supports it with evidence, and analyses what that evidence shows for the thesis. Harvard College Writing Center (n.d.-a) names those three elements and says the number of paragraphs should follow the number of steps the argument needs. Canterbury is firm that a topic sentence is a statement of understanding that needs evidence, not a fact, and Harvard's example sets a descriptive opener ("Marx wrote a critique of capitalism") against a claim about what the critique does.
How a paragraph ends: the guides differ
Swansea ends each paragraph with a summary sentence that gives your judgement and ties the point to the thesis. Harvard advises against ending on a summary or on a new idea, and suggests a last sentence saying what the reader can now understand. Both want the final sentence to be the writer's verdict, not the source's words; they differ on whether it restates.
Named patterns such as PEEL (Point, Evidence, Explain, Link) package this shape: University of Derby Library (2026) links a Point, Evidence, Explain example, and Victoria University Library (2026) teaches a TEEEL paragraph. They get a guide of their own. The claim, evidence, citation and "so what" check is in the essay assignment checklist, and whether to quote a source or restate it is in paraphrase, quote or summarise.
In what order should the points go?
In the order the argument needs. None of the guides read here sets a rule such as strongest point first or last, and Canterbury calls ordering a complex art with no straightforward rules. They offer tests instead.
- Dependence. Harvard's method: write the thesis at the top of a page, list the claims it needs and the sub-claims under each. A claim the others rely on comes first.
- The reverse outline. Harvard's check on a draft: list each paragraph's point, then ask whether a late point would work better earlier, whether two paragraphs make the same point, and whether one holds too many.
Where does a counterargument go in an essay?
A counterargument goes wherever a thoughtful reader would object, most often just before the conclusion, and never inside the conclusion itself, where there is no room to answer it. Harvard College Writing Center (n.d.-c) lists the usual places: before the conclusion, before the thesis when your essay answers someone else's argument, after the introduction, or wherever a reader might push back.
Harvard's method: state the objection and why a reasonable reader might hold it, then reply by showing a flaw, conceding part, or refining your claim. University of North Carolina at Chapel Hill Writing Center (n.d.-a) adds two rules: present the other side fairly, not as a straw man, and treat one or two serious counterarguments in depth rather than listing many.
What goes in an essay conclusion?
The conclusion answers the question by drawing the points together, and it adds no new evidence. Kent asks for a conclusion that directly answers the question; Swansea rules out new points and Canterbury new material or quotations; UNC lists evidence that belongs in the body among things to avoid; Harvard College Writing Center (n.d.-b) warns against restating the whole paper.
They differ on how far a conclusion may look outward. Kent and Canterbury describe restating the argument and its key points. University of North Carolina at Chapel Hill Writing Center (n.d.-b) says a conclusion can go beyond the assignment, to broader implications, a course of action or questions for further study; Harvard's "so what" and "now what" do the same, and Swansea ends by suggesting further research. In our view a sentence or two on implications is safe; a new argument is not. Whether the essay answers the question actually set is a separate check, in does my paper answer the assignment question.
How long should the introduction, body and conclusion be?
As long as your brief allows. These are the only figures the seven guides give, each as a rough guide.
| University guide | Introduction | Body | Conclusion |
|---|---|---|---|
| Kent (UK) | 5 to 10% of the word count | 80 to 90% | 5 to 10% |
| Derby (UK) | About 10% | About 80% | About 10% |
| Swansea (UK) | Around 10%, which it says many departments suggest | No figure | No figure |
| Victoria University (Australia) | 10% | 80% | 10% |
| Canterbury (New Zealand) | 10% | 4 to 8 paragraphs of 150 to 250 words, in a 1,500-word essay | 150 to 200 words |
| Harvard and UNC (US) | No figure | No figure | No figure |
Derby says its split is not a precise rule.
An essay outline example: one question, part by part
This outline is ours, for a question we wrote: "To what extent does homework improve the achievement of secondary school students? (1,500 words)". The word shares follow Canterbury's figures. The one study named is real; its findings come from its abstract: Cooper et al. (2006) synthesised US research since 1987, found generally consistent evidence of a positive link between homework and achievement, stronger in Grades 7 to 12 than in earlier grades, and found design flaws in every study.
Working thesis: homework is consistently linked with higher achievement in secondary school, more strongly than in primary, but the research shows an association rather than a proven cause, so the benefit is real but conditional.
| Part | Words | What it does | Evidence, and the tool |
|---|---|---|---|
| Introduction | About 150 | Why the question is argued over; "achievement" as grades and test scores; "secondary" as ages 11 to 18 (Grades 7 to 12 in the US studies); thesis; map | The brief, read with Check your paper |
| 1. The link | About 230 | Across research designs, homework goes with higher achievement | Cooper et al. (2006), built with Cite a source |
| 2. Older students | About 230 | The link is stronger at secondary level, the question's population | Cooper et al. (2006) |
| 3. What kind of homework | About 230 | A claim still to test: which homework helps | Not yet found; to search by claim in Find sources |
| 4. The objection | About 230 | Correlation is not cause; every study had design flaws | Cooper et al. (2006), stated fairly |
| 5. The reply | About 230 | Concede cause is unproven; say what the evidence supports, and that it is US research | Cooper et al. (2006) |
| Conclusion | About 175 | Answers "to what extent": a real, conditional link | Nothing new |
Paragraph 1 sets up what the rest depends on, paragraph 2 narrows it to the question's population, and the objection sits just before the conclusion, as Harvard suggests. Row 3 is left empty on purpose: a missing source is a plan to research, not a gap to fill with a guess.
What did Check your paper read from a real essay brief?
We gave Check your paper the published brief for Essay #2 in MIT's American History Since 1865 course (Horan, 2018) on 26 September 2026. It returned four rules, each with the sentence it was read from:
| What it asks | Asked for |
|---|---|
| Font size | 12 pt |
| Line spacing | 2 × |
| Word count | About 1,250 words |
| Citation style | Chicago |
Eleven sentences came back under "What it asks you to do, which no rule can test", among them the minimum of five assigned readings, three of them primary sources; the page numbers, footnotes and title; and the brief's one sentence on structure, which asks that a reader follow "both the overall argument and its progression through your essay". Two of the three marking criteria, and the due date, appeared in neither list, so read the brief yourself as well. The brief also wants Chicago footnotes, and Cite a source builds Chicago 18 in author-date form only.
Structure is what a rule cannot test: Theoretics QA, part of Max, judges the finished essay against every line of the brief, and checking against the marking rubric covers the criteria.
How EdCitation helps you structure an essay
For the sources that hold an essay's structure up, EdCitation is the best tool: it takes each reference from the publisher's record instead of composing one, something a chatbot cannot guarantee, and it checks an entire reference list in one pass. We ran it on the outline above.
Evidence, entries and the list
Find sources takes a topic or a claim and narrows it by kind of source, years and open access. Homework academic achievement, sorted by most cited, returned 113,413 results, led by Cooper and colleagues' synthesis in Review of Educational Research, cited 1,243 times; the next two were on other topics, so read titles as well as rank. A longer claim, time spent on homework and achievement in high school, returned 50,715 results led by a study of parental involvement: keep a claim to its key words.
Cite a source built the APA 7 entry from Crossref's record:
Cooper, H., Robinson, J. C., & Patall, E. A. (2006). Does homework improve academic achievement? A synthesis of research, 1987–2003. Review of Educational Research, 76(1), 1–62. https://doi.org/10.3102/00346543076001001
It set the record's title-case title in the sentence case APA 7 requires, so the entry pastes as it stands. Verify references found Cooper and colleagues' entry verified ("Title, year and first author match a published record."), and Zimmerman and Kitsantas's homework study, given the year 2007, doubtful, shown as "check this" ("A record with this title exists, but it was published in 2005, not 2007."). A reference that could not be checked is never shown as not found.
The whole essay
References from a file takes the uploaded essay, checks each reference in it and pairs each in-text citation with its entry: three checks a month with a free account, no limit with Pro at $8 a month. With Max at $24 a month, Theoretics QA reads the finished essay against the brief it was set and rewrites nothing. None of these writes a sentence of your essay, and none can promise a mark.
Quick questions
What are the three parts of an essay structure?
An introduction that states the thesis and maps the argument, body paragraphs that each make one point with evidence and analysis, and a conclusion that answers the question without new evidence.
How long should an essay introduction be?
The universities that give a figure suggest about 10% of the word count; Kent says 5 to 10%. Your brief or tutor overrides any such figure.
Can I put new evidence in the conclusion?
No. Kent, Swansea, Canterbury and UNC keep new material out of the conclusion, though UNC and Harvard allow a sentence or two on wider implications.
Can EdCitation check the structure of my essay?
Check your paper reads the brief into a checklist, free, and lists instructions about structure under what no rule can test. Theoretics QA, part of Max, judges the finished essay against that brief, quoting your text.
