How to Avoid Plagiarism: A Student Guide

What is plagiarism?

Plagiarism is the act of presenting another person's words, ideas, or work as your own without proper acknowledgement. In academic writing, this includes copying text without quotation marks, paraphrasing too closely without a citation, and using another student's work. Most UK universities treat plagiarism as a serious academic offence that can result in mark penalties, module failure, or in severe cases, expulsion.

It is important to understand that plagiarism can be unintentional. Poor note-taking habits, insufficient paraphrasing, and inconsistent citation practices can all lead to accidental plagiarism. The guidance below explains how to avoid it.

Types of plagiarism

Plagiarism takes several forms beyond copying text verbatim. Close paraphrasing involves restructuring a sentence whilst retaining most of the original wording, this is still plagiarism even if a citation is included. Mosaic plagiarism involves weaving phrases from a source into your own text without quotation marks. Understanding these distinctions helps you stay on the right side of academic integrity rules.

How to paraphrase correctly

Paraphrasing is the process of restating an idea from a source entirely in your own words, with a citation. Effective paraphrasing requires more than replacing individual words with synonyms, it involves fully understanding the source and reconstructing the idea from scratch in your own sentence structure.

The recommended approach is to read the source passage, close or set it aside, and then write your version without looking at the original. Compare the two afterwards to check that your wording and sentence structure are sufficiently different. For a detailed guide, read our article on how to paraphrase correctly.

When to use direct quotations

Direct quotations should be used sparingly in academic writing, they are most appropriate when the original wording is itself significant (for example, a legal definition, a famous theoretical statement, or a specific phrase being analysed). In most cases, paraphrasing with a citation is preferable to quoting.

When you do quote directly, the passage must appear in quotation marks, and the citation must include the page number: (Smith, 2021, p. 34). Quotations of more than approximately forty words are usually set as an indented block quote without quotation marks.

Cite every source you use

Every idea, fact, argument, or piece of data that you have taken from another source must be cited, even when you have paraphrased it in your own words. The only exception is information that is genuinely common knowledge and not specific to any particular source.

Using the correct referencing style for your subject is equally important. Common styles include Harvard, APA 7th, OSCOLA, Chicago, and Vancouver. For complete guides, see our articles on Harvard referencing and how to cite sources.

Use a plagiarism checker

Before submitting any assessed work, run it through a plagiarism checker. Many UK universities provide access to Turnitin, the same tool used by markers, through their student portals. GradeQuill also offers access to a plagiarism checker tool you can use before submission.

A plagiarism report highlights passages that match existing sources. Review any flagged sections carefully: some matches will be correctly cited quotations or common phrases that present no issue, whilst others may require paraphrasing or additional citation.

Self-plagiarism

Self-plagiarism, submitting your own previously submitted work, or significant portions of it, for a different assessment, is also treated as an academic offence by most UK universities. Each piece of submitted work must be original to that assessment.

If you are building on ideas from a previous assignment, you should cite your earlier work as you would any other source, and ensure the new submission develops those ideas rather than reproducing them. If you are unsure whether reusing material is permitted, consult your module handbook or personal tutor.
