The permitted scope is narrow, and it is written down

Where an advisor has not specified limits, the guidelines say editors should not go beyond simple correction of grammar, idiom, punctuation, spelling, and mechanics. The content and the overall structure of the text are to be retained as they stand.1 The document then names the specific standards in Editors Canada's Professional Editorial Standards 2024 that the work may draw on, ending at a short subset of the proofreading standards rather than the whole of them.1

For undergraduate work the position is stricter still. Editing an undergraduate text is restricted to flagging errors with notes and queries, and the graduate guidelines note that graduate editing is often more nuanced by comparison.1 An author who has commissioned commercial editing before is usually surprised by how much less is permitted here, and the surprise is better had before the money is spent.

Flagging, not fixing, is the working method

The guidelines are direct about technique. Editors should generally err on the side of flagging rather than fixing problems, naming sentence combining, comma splices, subject-verb agreement, and other mechanics of language as examples for the student to revise.1 Queries should be phrased to put the responsibility back on the student, so that "please clarify this sentence" is preferred over an editor's proposed reading of what the sentence might mean. Where a sentence has to be rewritten to show what the problem is, the student's own wording is retained as far as possible, and no new content is introduced.1

The record-keeping obligations follow from the same principle. The editor keeps a copy showing each editing iteration, whether that is a marked-up paper copy or a tracked-changes file, along with query sheets and correspondence. Some faculties require the student to submit that record alongside the original and the final version.1 The standards the guidelines draw on are published separately, as Editors Canada's Professional Editorial Standards.2 Editors Canada also recommends that the contract stipulate acknowledgment of the editor in the finished work, so that readers know a professional editor was involved.1

What a proofreader is genuinely useful for in academic work

Within that narrow scope there is a great deal to do, because academic manuscripts fail on conformity more often than on grammar.

References are the largest single category. The International Committee of Medical Journal Editors asks authors to provide direct references to original research sources wherever possible, and to verify references against a bibliographic source such as PubMed or against the original.3 Verifying that every in-text citation has an entry, that every entry is cited, and that the two agree on year and author order does not touch the argument.

Abbreviations are the second. ICMJE recommends using only standard abbreviations, notes that nonstandard ones confuse readers, and advises avoiding abbreviations in the title altogether.3 A manuscript that defines a term twice, or uses it before defining it, has a fault a reader can see and an author usually cannot.

Units and measurements are the third. ICMJE asks that length, height, weight, and volume be reported in metric units and that temperatures appear in degrees Celsius.3 A thesis that mixes conventions between chapters written years apart is easy to correct.

Editors Canada defines proofreading as examining material after layout or in its final format. Correcting errors in textual and visual elements, checking adherence to the design, and verifying the consistency of cross-references, running heads, and hyperlinks all fall inside that definition.4 In a dissertation, running heads, chapter numbering, table numbering, and appendix labels are exactly where the late errors live, because they were correct until the last reordering.

Where the editor's judgment stops

The same definitions record that proofreading is not a substitute for editing.4 A thesis with a structural problem does not acquire a structure by being proofread, and a proofreader who begins repairing the structure has stepped outside what the advisor authorized.

Nothing in the method allows an editor to settle a question in the student's own field. Whether a result supports a claim, whether a method was appropriate, and whether a source says what the student reports it says are matters for the student and their committee. What an editor supplies is a report on the words: what is inconsistent, what is misspelled, what is cited but not listed, and what a reader will stumble over.

Everything a client sends is treated in confidence, including unpublished research, data, and committee correspondence. EditFast works within whatever limits an advisor or an institution has set, and will work from the permission form where one exists.

The conversation that settles all of this takes about ten minutes and happens before any money changes hands. It is also the one step students most often leave until the manuscript is due.
