Essay Proofreading Checklist: 12 Checks Before You Submit

Somewhere in your final draft there is almost certainly an it's that should be its, a citation that does not quite match its entry in the reference list, and one sentence that made perfect sense at two in the morning. Proofreading is the pass that catches them before a marker does. It is not the same job as editing: by this stage you are not reshaping the argument, you are checking that the words on the page say what you meant, correctly and consistently. The twelve checks below take roughly an hour on a 2,000-word essay.

First, Break Your Own Reading Habits

Your brain reads what it expects to see, which is why you can read a paragraph five times and still miss a missing word. Spellcheckers have the same blind spot: they check words in isolation, not meaning. So change the conditions before you start.

• Print the essay if you can. Errors look different on paper.
• Change the font and size for the final pass so the page looks unfamiliar.
• Read aloud. You will hear dropped words and clunky syntax that your eyes slide over.
• Read the last sentence first, then the one before it, working backwards. It breaks the flow that hides mistakes.
• Leave a few hours between finishing and proofreading. Overnight is better still.
• Check that your spellchecker is set to UK English, not US English, or it will flag correct spellings and ignore wrong ones.

Checks 1–3: Spelling and Word Choice

1. Spelling, including variant consistency

Unless your department specifies otherwise, use UK spelling throughout: organise, analyse, behaviour, colour, centre, programme. Mixing analyse in one paragraph with analyze in the next looks careless even when the spelling itself is correct.

2. Homophones and near-misses

These survive spellcheck because both versions are real words: its/it's, affect/effect, their/there/they're, principle/principal, practice/practise, complement/compliment, dependent/dependant, discrete/discreet, lead/led, lose/loose. Search for each one deliberately rather than hoping to spot it.

3. Words autocorrect chose for you

Watch for plausible-but-wrong substitutions, especially in academic vocabulary: infer when you mean imply, phenomena used as a singular, comprised of where composed of belongs. Scrutinise any word you would not use in conversation. Then read names, module codes and place names letter by letter — that is a check spellcheckers handle badly.

Checks 4–6: Grammar at Sentence Level

4. Subject–verb agreement

Long subjects hide errors. The range of factors influencing student retention is — not are. Take note of collective nouns and phrases such as one of the students who.

5. Tense and voice

Most essays hold arguments in the present tense and describe methods or historical events in the past. Choose your convention and stay with it. Sudden switches mid-paragraph read as confusion rather than sophistication.

6. Complete sentences and clean clauses

Check every sentence has a subject and a finite verb, and that commas are not doing the work of full stops. Dangling modifiers are the classic slip: Having analysed the data, the conclusion was clear suggests the conclusion analysed the data. Finally, look at sentence length. A run of forty-word sentences exhausts the reader; a short one after them lands hard. Aim for variety, not uniformity.

Checks 7–9: Punctuation and Mechanics

7. Apostrophes

Test each one. Its is possessive; it's means it is. Students, student's and students' all say different things. Decades take no apostrophe: the 1990s. For names ending in s, follow your style guide consistently (James's or James' — pick one and hold it).

8. Commas, semicolons and colons

Commas separate items, mark off non-essential clauses and follow introductory phrases. They cannot join two independent clauses on their own — that is a comma splice, and a semicolon or full stop is the fix. Colons introduce a list, a quotation or an explanation, and whatever follows should complete the sentence.

9. Quotations, dashes and capitals

Punctuate quotations according to your style guide. Use ellipses for omissions, square brackets for your own insertions, and block quotations — indented, without quotation marks — for longer passages. Distinguish hyphens from en dashes: well-known author takes a hyphen, 2019–2023 takes an en dash. On capitals, keep heading styles identical throughout and do not capitalise subjects or job titles unless they are proper nouns.

Check 10: Referencing, End to End

Markers notice referencing errors faster than almost anything else. Work through this list slowly.

• Every in-text citation appears in the reference list, and every entry is cited at least once.
• Names and years match exactly. Smith (2019) in the text and Smith (2020) in the list is an easy, common slip.
• Page numbers are given for direct quotations and specific claims.
• One style is used throughout — Harvard, APA, MLA, OSCOLA or your department's variant — with consistent punctuation and italics.
• Quotations are word-perfect, checked against the source rather than your notes.
• Secondary citations (cited in) are formatted correctly and used sparingly.
• The list is in the right order (alphabetical or numbered) with consistent hanging indents.

Check 11: Formatting and Presentation

Confirm the small things: font and size, line spacing, margins, left-aligned rather than justified text. Check your word count and whether it includes quotations, footnotes and references. Make sure headings follow one system, page numbers are present, and the title page shows what your department requires — sometimes a student number instead of a name for anonymous marking. Tables and figures should be numbered, captioned, mentioned in the text and legible if printed in greyscale. Finally, name the file as instructed and submit it in the requested format.

Check 12: Read the Brief One More Time

Go back to the assignment question and the marking criteria. Does your essay answer the question that was actually set, rather than a related one you found more interesting? Is every required element present? Then check the practical details: deadline and time zone, submission portal, any declaration form, and the confirmation that your upload succeeded.

The Final Twenty Minutes

Do the closing pass in a fixed order so nothing gets skipped.

1. Run the spellchecker with the correct language set and accept only the changes you agree with.
2. Read the whole essay aloud, slowly, one paragraph at a time.
3. Check the reference list against every citation.
4. Check formatting, word count and file name.
5. Submit, then save the confirmation and keep a copy of the exact version you sent.

Submit with time to spare rather than at midnight, when portals slow down and your judgement is worst. If something goes wrong after submission, contact your tutor promptly and check your departmental handbook — it, not a checklist, is the authority on deadlines, extensions and referencing rules. And if you find one last typo while reading the confirmation email, remember that every editor has done the same thing. The difference is that you will have caught the other forty.
