How to Avoid Plagiarism

Plagiarism is submitting someone else's work or ideas as your own without proper attribution. It can happen intentionally or accidentally — but universities treat both the same way. This guide explains the different types, the most common mistakes students make without realising, and practical steps to keep your work clean.

Types of Plagiarism

• 📋

  Direct (copy-paste) plagiarism

  Copying text word-for-word without quotation marks or citation. The most obvious form — and the easiest to detect.

• ✂️

  Patchwriting

  Replacing a few words in a source sentence while keeping the same structure and ideas. Looks like paraphrase but isn't — the thinking is still the source author's, not yours.

• 🔄

  Self-plagiarism

  Submitting work you've already submitted for another assignment — even your own previous work — without disclosure. Many students don't know this counts as plagiarism.

• 💡

  Idea theft

  Taking someone else's argument, structure, or framework and presenting it as your original thinking, even if you reword the sentences.

• 🤝

  Collusion

  Working with another student and submitting the same (or very similar) work, when the assignment was supposed to be independent.

Patchwriting vs True Paraphrase

Patchwriting is the most common unintentional plagiarism. It looks like you rewrote something, but you're still following the original so closely that it's essentially the same text.

Self-Plagiarism

Reusing your own previously submitted work without declaring it is academic misconduct at most institutions. The rules vary by university, but the general principle is: each piece of assessed work should represent new thinking and effort for that specific assignment.

• What counts: Resubmitting entire paragraphs, sections, or a whole essay from a previous module
• What's usually fine: Building on earlier research, reading previous work to remind yourself of arguments, or reusing ideas you developed earlier (as long as you cite your own work)
• When in doubt: Ask your module tutor before submitting — it's always better to ask first

Understanding Turnitin

Turnitin compares your submission against its database of websites, journals, books, and previously submitted student papers. It produces a "Similarity Score" — a percentage showing how much of your text matches other sources.

Common reasons for high Turnitin scores that aren't plagiarism

• Your reference list matching other papers (this is expected and should be excluded from the score)
• Correctly cited direct quotations showing as matches
• Standard academic phrases like "This essay will argue..." matching across thousands of papers
• Assignment instructions included in the submission

AI Tools and Academic Integrity

The rules around AI-generated content differ significantly between institutions. Before using any AI tool in your academic work, check your institution's specific policy — they vary from "permitted with disclosure" to "zero tolerance."

Common institutional positions (as of 2024)

• Permitted with full disclosure: You can use AI tools but must declare which tool, how you used it, and cite it. The work must still be substantially your own thinking.
• Permitted for specific uses only: AI may be allowed for brainstorming, grammar checking, or literature search — but not for generating essay content.
• Not permitted: Any AI use constitutes academic misconduct. Most written assessments currently fall into this category at UK universities.

Prevention Checklist

• ✓Cite every source you paraphrase, summarise, or quote — even if you rewrite it entirely
• ✓Put all directly copied text in quotation marks with a page number citation
• ✓Close the source before writing your paraphrase — write from understanding, not from looking
• ✓Keep your notes and drafts — they prove your process if a plagiarism allegation is ever made
• ✓Check your institution's policy on self-plagiarism and AI tools before you start
• ✓Run your own Turnitin check (if available) before final submission
• ✓If you're unsure whether something needs a citation, cite it — over-citing is never penalised
