Authorship Review With Highlights: A Fair Method
When a teacher is unsure who wrote an essay, the fairest evidence is the writing process itself. Highlights make that process visible: what changed between drafts, which sources were really read, and which sentences the student can explain.
Authorship questions are among the hardest conversations in teaching. An accusation that turns out to be wrong damages trust for a whole year, and a question that is never asked lets a student skip the learning the assignment was for. The way through is to make the conversation about the work and the process rather than about a suspicion. Highlighting is a simple, low-tech way to do that, and it works for students reviewing their own work as well as for teachers.

In short
A fair authorship review looks at process, not style. Collect drafts, notes and annotated sources when the assignment is set, highlight what changed between drafts, check each source claim against its source, and ask the student to explain chosen sentences. The process record and the conversation together support a conclusion; no single signal does.
Four principles before you start
- Tell students in advance. If drafts, notes and source annotations will be part of how work is reviewed, say so when the assignment is set. Review then becomes a normal step, not an event.
- Collect process, not just product. An outline, a first draft, a revised draft and an annotated source list take students little extra effort and give you far more to look at than a single final file.
- Start from curiosity. The first question is always "walk me through how you wrote this", never "did you use a tool".
- No single signal decides. Style marks, a software score, or a feeling are reasons to look closer. Only the conversation and the process evidence together support a conclusion.
The method in three passes
Highlight what changed between drafts
Lay the first and final drafts side by side and mark, in yellow, every passage that is new or substantially rewritten in the final version. Real revision leaves an uneven trail: some paragraphs barely change, some are rebuilt, and a few ideas appear only late. A final draft that shares almost nothing with the first, arriving in one polished step, is worth asking about.
Highlight the claims that rest on sources
In a second colour, mark each sentence that depends on a source. Then open the source and find the passage it depends on. Our guide to annotating sources to verify claims covers this in detail. Claims that match their sources show the student read them; claims attributed to sources that do not say them are the most concrete thing you will find.
Highlight the sentences to ask about
In a third mark, choose three to five sentences: the strongest argument, the most specific detail and any passage whose style stands out from the rest. These become the questions for the conversation. The close-reading patterns guide explains which style habits are worth choosing.
A worked example: one paragraph across two drafts
Here is a paragraph from an imagined student essay on street trees, in its first draft and its final draft, with the marks the three passes would leave. The topic is neutral; the shape of the revision is what matters.
| Version | Text | Marks and notes |
|---|---|---|
| First draft (dated Monday) | Trees in cities are good because they make the air cleaner and give shade. Some studies say they also reduce stress. I think cities should plant more. | No marks. This is the baseline. |
| Final draft (dated the following Friday) | Street trees lower the air temperature in the streets they shade, which is why several councils now count tree cover as part of their summer heat plans. One review of urban greening studies reported that residents of tree-lined streets described lower stress, although the review noted that most of those studies relied on self-report. A planting programme therefore has a case that rests on temperature first and wellbeing second. | Yellow on the whole first sentence and the last: both are new. Green on "one review of urban greening studies reported": a source claim. The student's annotated copy of the review has that passage highlighted, with the self-report caveat marked, and a highlight link in the margin. Third mark on "temperature first and wellbeing second": the sentence to ask about. |
In the conversation, the reviewer asks two questions: where did the self-report caveat come from, and why does temperature come first? A student who read the review will point to the marked passage and explain that the caveat made them trust the temperature evidence more. That answer, together with the dated drafts, is the review. The style of the final paragraph, which is smoother than the first, is not evidence of anything except revision.
Running the conversation
Sit with the student and the marked pages. Ask them to explain the highlighted sentences in their own words, to say where a source claim came from and to describe what changed between drafts and why. Students who wrote the work can usually do this easily, even when they are nervous, because they remember making the choices. Students who did not often struggle with the specifics while handling the generalities well. Listen for the specifics. Keep notes of what was said, and share them with the student afterwards.
Be ready for good explanations. A student may have used a grammar tool on the final pass, worked with a tutor or a parent, or written the draft in a different language and translated it. Your school's policy decides which of these are acceptable; the conversation's job is to establish what actually happened.
For students: review your own work first
The same three passes protect you. Keep your drafts and your annotated sources, and before you submit, mark your own final draft: can you point to where each source claim comes from, and could you explain every highlighted sentence if asked? If a paragraph came from a tool and you cannot explain it, rewrite it in your own words or cut it. A folder of drafts and marked sources is the most convincing evidence of authorship you can have, and it costs nothing to keep. Share the key passages with your teacher using a highlight link so they land exactly on the sentence you mean.
Academic integrity and AI: the record a teacher can check
The method on this page is a way of building a record, and a record is what academic integrity policies increasingly ask for when AI tools are in the picture. Rather than trying to detect what a tool may have done, the record shows what the writer did. Every item in it can be checked by a teacher, an editor or a reader without special software.
| Item in the record | Who keeps it | What it shows | How a teacher checks it |
|---|---|---|---|
| Dated drafts or version history | Student | The work grew over days, in steps | Open the history; look for uneven, plausible growth rather than one large paste |
| Sources with highlights and notes | Student | The sources were read, and what was taken from each | Open a marked source; ask the student to explain one highlighted passage |
| A highlight link per source claim | Student | Each claim in the essay leads to a passage in a source | Click the link; confirm the passage says what the essay says |
| The marked final draft | Teacher | Which passages were asked about and why | Kept with the conversation notes, dated |
| Notes of the conversation | Teacher, shared with the student | What was asked and what was answered | Both parties hold a copy |
For the source claims in particular, the student can run a verification log that records each source claim and its link before submitting, which turns the second pass of the review into something they have already done. The wider set of habits, from marking a text to exporting the marks, is collected in the site's guides to highlights as a record of reading and writing.
Pitfalls in an authorship review
- Acting on a score. A number from a checking tool is a reason to look, never a finding. Decisions rest on the record and the conversation.
- Comparing the student's style with an imagined average. Plain, formulaic or unusually formal prose is common among careful writers and among those writing in an additional language.
- Reviewing without the student. A review done at a desk, without asking the writer anything, has no way to hear the good explanations.
- Asking about the tool first. "Walk me through how you wrote this" gets a fuller account than "did you use a tool", and it is fairer.
- Not writing it down. Without dated notes of what was asked and answered, the review cannot be revisited if the student appeals or the teacher changes their mind.
Making it routine in class
The strongest approach is to make process visible from the start of the year. The activities in highlighting activities for teachers, such as marking the one sentence that carries an argument, give students practice explaining their choices out loud. When every student is used to annotating sources and talking about drafts, an authorship conversation is just another version of an ordinary lesson.
This method belongs with the other classroom pages in the study pages on this site. The underlying marking habits come from a highlighter colour code that works, and the evidence for why explaining your marks matters is in the research review on highlighting and memory. Students can prepare for this conversation in advance by marking up their own drafts as a process record and by writing a short disclosure of any tool use. Teachers weighing an automated score should read the limits of AI text detectors first.
Common questions
How can teachers check if a student wrote their own essay?
Collect drafts and annotated sources as part of the assignment, compare the drafts, check source claims against the sources, and ask the student to explain chosen passages. The process evidence and the conversation together are far more reliable than any single signal.
What should students keep to show they wrote their work?
Outlines, dated drafts, notes and the sources they read with their own highlights and comments. A version history in a document editor also helps.
Is it fair to question a student based on writing style?
Style alone is a weak reason. Use it only to choose which passages to ask about, and let the student's explanation and process evidence carry the decision.
How do highlight links help in an authorship review?
They let a teacher or student point at an exact sentence in a shared source or document without sending a copy, which keeps the discussion precise.
Can AI detection software be used as evidence of academic misconduct?
Institutional guidance generally treats a detection result as one signal that may justify a closer look, not as proof on its own. A fair process asks for the student's drafts, sources and explanation before any conclusion, and records what was said. This page's method supplies that evidence whatever tools a school uses.
What does academic integrity mean when AI tools are allowed?
It means following the rule that applies to the assignment, saying clearly what any tool did, and being able to show your own work behind the result: the sources you read, the drafts you wrote and the choices you can explain. Permission to use a tool does not remove the responsibility for the work.
