What Is Turnitin and How Does It Work?
Turnitin is a tool that checks if your writing is too similar to other sources. It compares your paper with:
-
Other students' papers
-
Online articles and websites
-
Academic journals
When Turnitin finds matching text, it highlights the parts and gives you a similarity score. A high Turnitin similarity score doesn't always mean you copied, but it may mean you need to revise some parts.
Common Causes of High Similarity Scores
Sometimes students get a high Turnitin score even when they didn't mean to copy. Here are some common reasons:
-
Using too many direct quotes, even with proper citation
-
Repeating phrases from the assignment prompt or textbooks
-
Relying on templates or sample essays found online
-
Not formatting references or citations correctly
Even common academic phrases or definitions can get flagged if they appear in many other papers.
How to Reduce Similarity on Turnitin
This is the most crucial part. To truly lower your similarity score, you need to master how you use information from others and how you express your own ideas.
Master Citing and Referencing
Properly giving credit to your sources is absolutely essential. Here's how to do it effectively:
-
Use direct quotes (copying text word-for-word) carefully. Always put quotation marks around the text and immediately cite the source, like this: (Smith, 2023). Use direct quotes sparingly, only for specific definitions or powerful statements that cannot be rephrased.
-
Paraphrase properly. A common mistake is to just swap a few words. That's not enough. True paraphrasing means fully understanding the original text, then rewriting it in your own words and sentence structure without looking at the original.
-
Always cite paraphrased or summarized content. Even when you paraphrase or summarize, you must still credit the original source.
-
Stick to one citation style. Always use a single citation style (APA, MLA, or Chicago) throughout your paper. Check with your instructor about which one to use.

Don't Overuse Direct Quotes
Using too many direct quotes can make your similarity score shoot up because Turnitin flags exact matches, even if you cite them. Instead of quoting long chunks, try summarizing the main point in your own words and add your own thoughts to show you understand it. If you must use a quote, keep it short and use it only for something really impactful. Mixing quotes with your own analysis keeps your paper unique and lowers your score.
Write Original Content
The best way to avoid a high similarity score is to make your work your own. Here's how you can do that:
-
Share your own ideas or opinions based on what you've learned.
-
Add personal examples or insights to stand out.
-
Stay away from copying templates or common phrases from websites, since Turnitin can catch those.
Use Turnitin's Report to Improve Your Paper
The Turnitin report is an invaluable tool for helping you lower your similarity. Some settings can exclude quotes, bibliographies, or small common phrases (if formatted correctly). More importantly, open the similarity report and carefully examine the highlighted sections. Turnitin clearly indicates the source of the match. Your focus should be on these areas:
-
Rephrase these sections.
-
Add or refine proper citations.

Use the report to guide your changes and focus on how to reduce similarity in Turnitin effectively before final submission.
What's an "Acceptable" Similarity Score?
There isn't one fixed number that applies to everyone. What counts as an "acceptable" Turnitin similarity score often depends on your school, your instructor, and the type of assignment. However, here are some general guidelines:
Turnitin Similarity Score | Interpretation | Action Needed |
---|---|---|
0–10% | Highly original; matches are likely titles or common phrases. | Minimal changes needed. |
11–20% | Usually acceptable; includes cited quotes or references. | Review report to ensure proper citation. |
21–40% | Potential concern; may indicate over-reliance on sources. | Rephrase flagged sections and verify citations. |
>40% | Often too high; suggests heavy use of unoriginal content. | Revise extensively to reduce matches. |
Keep in mind that the score alone doesn't tell the whole story. Always open the Turnitin report to check what was flagged and make sure all borrowed ideas are clearly cited.
