How to Avoid Plagiarism: 8 Practical Tips for Students

Key takeaways

• Plagiarism is presenting someone else's words, ideas or work as your own without credit, even by accident.
• Avoid it by citing every source, putting exact words in quotation marks, and paraphrasing properly.
• Reusing your own previous work without permission (self-plagiarism) also counts.

Types of plagiarism

• Direct: copying text word for word without quotation marks and a citation
• Mosaic / patchwriting: mixing copied phrases with your own words, or swapping in synonyms
• Paraphrasing without citation: rewording an idea but not crediting it
• Self-plagiarism: resubmitting your own earlier work without approval
• Accidental: forgetting a citation or mixing up notes and your own writing

8 ways to avoid plagiarism

1. Take careful notes. Mark quotes, paraphrases and your own ideas differently, and record source details as you go.
2. Cite as you write. Add citations while drafting, not afterwards.
3. Quote exact words. Use quotation marks and a page number.
4. Paraphrase properly. Read the passage, close the source, write it in your own words and structure, then compare and cite.
5. Cite ideas, not just words. Theories, data and arguments from others need credit.
6. Know what counts as common knowledge. Widely known facts ("Paris is the capital of France") don't need citations. Specific statistics do.
7. Use a citation style consistently. Follow APA, MLA, Chicago or Harvard.
8. Check your work. Run a plagiarism checker if your school provides one, and review any matches.

Paraphrasing example

Original: "Sleep deprivation impairs attention, working memory and decision-making in adolescents." (Kim, 2021, p. 5)

Poor paraphrase (patchwriting): Lack of sleep impairs attention, memory and decision-making in teenagers.

Good paraphrase: Teenagers who don't get enough sleep struggle to focus, retain information and make sound choices (Kim, 2021).

Frequently asked questions

Is using AI plagiarism?

Policies vary by institution. Many schools treat submitting AI-generated text as your own as an academic integrity violation. Always follow your school's policy and disclose AI use where it's required.

How much similarity is acceptable on Turnitin?

There's no universal number. Matches in quotes and references are normal. What matters is whether the matched text is properly quoted and cited.

Do I need to cite my own previous paper?

Yes. If you reuse your own work, cite it and get your instructor's permission.
