Academic proofreading and editing: what help is allowed and how to use it
Ask a friend, a tutor, or a professional service to look over your assignment before you submit it, and a new worry sits alongside the old one: will this get flagged as someone else's work, or worse, as AI-generated. The worry is reasonable. Universities have tightened proofreading policy over the past two years, GenAI-powered writing tools blur what counts as "just fixing grammar," and the line between compliant proofreading and contract cheating is not always where students assume it sits. This guide sets out exactly where that line is, what a proofreader is and is not allowed to touch, how the rules shift between taught and research degrees, and what compliant support looks like when English is your second language.

Editing, proofreading, and revision are different jobs
The words get used interchangeably in everyday speech, and that habit is exactly what gets students into trouble when a university policy uses one of them with a precise, narrower meaning. Revision is the broad structural pass: does the argument hold, does the evidence support the claim, does each section do the job the brief asked for. Editing works one level down, on content, structure within paragraphs, clarity, style, and citation, once the bigger structural work is settled (The Writing Center, University of North Carolina at Chapel Hill, n.d.). Proofreading is the final, narrowest stage: surface errors only, spelling, grammar, punctuation, formatting (The Writing Center, University of North Carolina at Chapel Hill, n.d.; University of Waterloo, n.d.).
The order is fixed for a reason, and it matters as much for a second reader as it does for you. Correcting a sentence's grammar before its paragraph has survived the structural pass risks polishing text that gets cut an hour later; there is no point fixing what might still be deleted (University of Waterloo, n.d.). That is also why a policy that permits "proofreading" is not automatically permitting "editing," and definitely not permitting "revision." When you ask someone for help, you are asking for one specific, narrow service, and the label you use for that request is the label your university will hold you to. For the practical mechanics of running these passes yourself, our editing and proofreading checklist walks through the multi-pass method step by step.
Where the integrity line sits
Here is the principle that runs underneath every university policy on this, worded differently by different institutions but consistent in substance: proofreading means pointing out surface errors; the moment a third party starts changing content, argument, or structure, the work is no longer proofreading, it is editing or ghost-writing, and it counts as academic misconduct (The University of Edinburgh, 2025).
What a compliant proofreader can do is narrow and local. They can correct spelling, punctuation, grammar, and syntax, usually a single word or mark inside a sentence you already wrote (The University of Edinburgh, 2025). They can flag a passage that is unclear, repetitive, or overcomplicated and explain why, without rewriting it themselves (The University of Edinburgh, 2025). And every change should be visible through Track Changes or comments, so authorship stays traceable to you (The University of Edinburgh, 2025).
What crosses the line is broader than most students expect. Rewriting a sentence or paragraph, changing your voice, making the prose "sound more academic," is editing, not proofreading (The University of Edinburgh, 2025; Swansea University, n.d.). Reordering your argument, moving sections, or changing cross-references is a structural change, not a surface fix (The University of Edinburgh, 2025). Adding new content, whether that is a sentence, a data point, a formula, or a piece of evidence, is not proofreading under any definition (The University of Edinburgh, 2025). The same applies to checking or correcting whether your facts, data, or calculations are actually right, to touching your reference list or switching citation systems, to translating any part of your work into another language, and to trimming text purely to hit a word limit (The University of Edinburgh, 2025).
Two things follow from this that students routinely underestimate. First, many UK universities do not permit professional third-party proofreading or editing services at all for taught undergraduate and postgraduate-taught work, except where it has been approved as a reasonable adjustment, such as through a Disabled Students' Allowance; postgraduate research and thesis work is generally permitted to use proofreading support, but inside a tighter framework (Swansea University, n.d.). Second, a correction that is "so substantial it is no longer your own work" is classified as contract cheating, whether or not any money changed hands (Loughborough University, n.d.). One university's guidance puts the boundary plainly: you can be helped with proofreading or given feedback; having your work written for you or edited at depth is not acceptable (Victoria University of Wellington, 2026). None of this is uniform across institutions or degree levels, which is exactly why the rule that matters most is the least glamorous one: check your own university's policy and your assignment brief before you arrange any outside help, every time, because the permitted line moves between schools and between years of study.
If you are weighing up whether to use a proofreading service at all, our companion guide on whether using a proofreading service counts as cheating works through that permission question university by university.
Proofreading when English is your second language
If English is not your first language, the calculation changes again, because the errors you are catching are often not careless slips but patterns tied to how your first language organises meaning. That is a different, and legitimate, skill to build, and it does not require anyone else touching your sentences for you. Our companion guide on proofreading academic writing as a second-language writer covers the specific error patterns, the language learning log, and the single-error-per-pass technique that university writing centres recommend for exactly this situation.
GenAI tools and proofreading
Online proofreading tools sit inside the same integrity line, not outside it, and that line has moved with the technology. If the tool you are using runs a generative AI feature, one that changes your tone, shortens your text, or paraphrases a sentence for you, using it counts as using AI, and current guidance requires you to declare that use the same way you would declare any other AI assistance (The University of Edinburgh, 2025). A tool that only flags an error for you to fix yourself is a different category from one that rewrites the sentence and hands it back finished; the first keeps the judgement with you, the second makes the judgement for you and then hides the fact that it did. This is the same test that applies to a human proofreader, applied to software: correcting is fine, rewriting is not, and either way, the fact that a tool touched your text at all needs to be visible, not buried.
When to get help, and what compliant help looks like
The compliant version of "getting help" is narrower than most services advertise, and it is the version MAAS builds its academic integrity check and academic support services around: a mentor points out where a sentence is unclear, where a paragraph has drifted from its argument, or where a citation is inconsistent, and explains why, but the sentence, the paragraph, and the fix stay yours to write. Nothing is rewritten on your behalf, nothing is translated, and nothing is submitted under an outside author's phrasing. Every suggestion is left visible through Track Changes, so your supervisor or marker can see exactly what was flagged and confirm that the words on the page are still yours.
If your goal is a compliance check before you submit, an academic integrity check reviews your draft against the boundary set out above and flags anything that risks reading as more than surface correction. If your goal is ongoing support through a longer piece of work, academic support pairs you with a mentor who reviews drafts against your brief across the writing process, always in the advisory role described here. Either way, the test stays the same: did a person fix the sentence, or did they tell you what was wrong with it so you could fix it yourself. Only the second one is proofreading.
Frequently asked questions
Is proofreading allowed at my university?
It depends on the university and your level of study, so there is no single answer. Many UK universities restrict or ban professional third-party proofreading for taught undergraduate and postgraduate-taught assessment, unless it has been approved as a reasonable adjustment; postgraduate research work is generally allowed to use proofreading support, but within stricter limits than taught coursework (Swansea University, n.d.). Always check your own institution's policy and your assignment brief before arranging outside help.
Does proofreading count as cheating?
Proofreading itself does not, provided it stays limited to surface-level correction: spelling, punctuation, grammar, and syntax, with changes visible through Track Changes (The University of Edinburgh, 2025). It becomes misconduct once the correction is substantial enough that the work is no longer genuinely yours, which universities classify as contract cheating regardless of whether payment was involved (Loughborough University, n.d.).
What is a proofreader allowed to change, exactly?
Local, sentence-level correction only: fixing a spelling error, a punctuation mark, or a grammar mistake, and flagging (without rewriting) passages that are unclear or repetitive. A proofreader should not rewrite sentences, reorder your argument, add new content or evidence, correct your facts or data, alter your reference list, translate any part of the text, or cut content purely to meet a word limit (The University of Edinburgh, 2025).
Is it a problem to ask a friend to read my assignment?
It depends on what they do with it. A friend who points out a typo, an awkward sentence, or a confusing paragraph and lets you fix it yourself is proofreading. A friend who rewrites your sentences, restructures your argument, or writes any new material for you has moved into editing or ghost-writing territory, which most universities treat the same way regardless of whether the helper was paid (Victoria University of Wellington, 2026).
Do I need to declare an AI proofreading tool?
Yes, if the tool does more than flag surface errors. A tool with a generative AI feature that changes your tone, shortens your text, or paraphrases sentences for you counts as AI assistance and needs to be declared under current university guidance, the same as any other use of AI in your work (The University of Edinburgh, 2025).
