Why Your Turnitin Score Might Look Higher Than Expected
Submitting a paper and seeing a red or orange similarity percentage can be an anxious moment for any student or researcher. It is natural to worry that your work might be flagged for plagiarism. However, before you panic, it is crucial to understand that the total similarity index displayed on the Turnitin dashboard is not the final verdict on the originality of your writing.
One of the most common sources of confusion is the category labeled "Excluded Quotations." If your score looks high, but a significant portion of the matches are categorized under this exclusion, the actual risk is often much lower than the headline number suggests. Understanding this distinction is the first step toward interpreting your report correctly and ensuring your academic integrity is preserved without unnecessary stress.
What Are "Excluded Quotations"?
Turnitin’s matching engine compares your text against a vast database of sources, including the internet, academic journals, and previously submitted papers. When your text matches a source, Turnitin highlights it in color. However, not all matches are treated equally in the final calculation of your similarity index.
Excluded Quotations refer to text that you have explicitly quoted from another source and placed within quotation marks. Because you have correctly attributed this text to the original author, Turnitin recognizes that this is not plagiarism but rather an appropriate use of direct citation. Therefore, these specific matches are excluded from the calculation of your final similarity score in many institutional settings, or at least flagged differently so that instructors can distinguish them from unattributed matches.
It is important to note that the visibility and treatment of these exclusions can depend on how your institution has configured Turnitin. Some professors will see the "Excluded Quotations" listed separately from "Excluded Sources" (like references and bibliography), while others may have a setting that hides them entirely from the main score view.
How to Locate This Data in Your Report
When you open your Turnitin similarity report, do not just look at the big number in the center of the screen. You need to dive into the details to see how that number is composed. Here is how you can find the breakdown:
- Check the Settings Panel: Look for the gear icon or the settings menu within the report. Ensure that the option to "Show excluded quotations" is enabled if you want to see them explicitly.
- Review the Source List: On the left-hand side of the report, you will see a list of sources that matched your text. Look for sources that have a specific icon or label indicating they are quotations.
- Examine the Color Coding: In the document view, direct quotes are often highlighted in a specific color (sometimes a darker shade or a distinct hue compared to paraphrased matches). Hovering over these highlights usually reveals the source and whether it is marked as a quotation.
Quotations vs. References vs. Bibliography
It is vital to distinguish between three types of excluded text, as they serve different purposes in your paper:
- Direct Quotations: Word-for-word text from another author, placed in quotes and cited. These are usually excluded from the similarity score because they are intentionally copied with permission.
- References/Bibliography: The list of works cited at the end of your paper. These are standard academic practice and are almost always excluded from the similarity index because they consist of titles and author names, not original content.
- Excluded Sources: Specific databases or publishers that your instructor has chosen to ignore for the comparison (e.g., student paper repository) to focus on external matching.
Why a High Score Doesn't Always Mean Plagiarism
Imagine you wrote a 10-page paper and used five long, direct quotes from a key theoretical text. If those quotes make up 20% of your word count, and the rest of your writing is original, your raw matching text might be high. However, because those 20% are properly quoted, the "Excluded Quotations" category will hold a significant weight. The remaining 80% of your text, which is your own analysis and synthesis, is what truly matters for academic integrity.
If your score is high primarily due to excluded quotations, your paper is likely in good standing. The high number is a technical artifact of the matching process, not an accusation of misconduct. The key is to ensure that every single instance of text in the "Excluded Quotations" section is indeed a proper, attributed quote. If you find unattributed text in this section, that is where you need to pay attention.
Ethical Ways to Reduce Unnecessary Similarity
While you cannot change how Turnitin calculates exclusions, you can write in a way that minimizes confusion and keeps your effective similarity score low. Here are ethical strategies to consider:
Paraphrase More, Quote Less
Use direct quotations sparingly. Only quote when the original author's phrasing is iconic, precise, or necessary for critical analysis. For the majority of your paper, paraphrase the ideas in your own words. Paraphrasing demonstrates your understanding of the material and significantly reduces the amount of text that matches source material, even if it is properly cited.
Verify Your Citation Formats
Ensure you are using the correct citation style (APA, MLA, Chicago, etc.) required by your institution. Incorrect formatting can sometimes cause software to fail to recognize a text as a proper quote or reference, leading to it being counted toward your similarity score. Double-check that quotation marks are used for direct quotes and that in-text citations are present immediately after the quote.
Use a Reliable Report for Pre-Submission Checks
Before you hit the final submit button, it is wise to check your own similarity. Many students use services like TurnPro AI to get an official Turnitin similarity and AI-writing detection report in non-repository mode. This means your paper is checked against the same databases Turnitin uses, but it is never stored in the repository, so it won't accidentally match your own submission later. With plans starting at just $2 and reports arriving in 5-30 minutes, you can review your "Excluded Quotations" and other matches privately, fix any formatting errors, and submit with confidence.
When to Contact Your Instructor
If you have reviewed your report and believe the similarity score is unfairly high due to technical issues, such as common phrases in your field being flagged, or if you have questions about how your institution interprets "Excluded Quotations," reach out to your professor or academic integrity office. Provide them with the specific sections of your report in question. Most instructors are understanding when students demonstrate that they have made a good-faith effort to cite correctly.
Remember, the goal of academic writing is to engage with existing literature transparently. A high similarity score is just a starting point for that conversation, not the end of it. By understanding the nuances of Turnitin’s report, you can move from panic to clarity, ensuring your work is presented as the original, rigorous scholarship it is.
