Direct answer
When you submit an academic paper to Turnitin, one of the most common concerns is how properly quoted text appears in your similarity report. Many students worry that their direct quotes—even when correctly formatted with quotation marks and citations—will be flagged as plagiarism and inflate their similarity score. Turnitin's AI writing detection and similarity technologies work together to identify matching text, but the way quotes are handled depends on instructor-configurable settings rather than automatic penalties [1]. Understanding this distinction is essential for submitting your work with confidence and interpreting your report accurately.
How Does Turnitin Handle Quoted Text in Similarity Reports?
Turnitin's Similarity Report identifies text that matches content in its vast database, which includes academic journals, student papers, and web pages. When your paper contains a direct quote enclosed in quotation marks with a proper citation, Turnitin still detects that text as a match against its sources because the quote itself originates from an existing publication. However, Turnitin provides instructors with a powerful filtering option called "Exclude Quotes," which allows them to remove all quoted material from the similarity calculation entirely [2]. This means that whether your quotes affect your similarity score depends entirely on your instructor's settings rather than on any inherent wrongdoing in your writing.
If quotes are included in the analysis, the matched quoted text appears highlighted in the report with a clear link to its original source, distinguishing it from unacknowledged copying. The key distinction is that properly cited quotes are not considered plagiarism, even though they may contribute to the overall match percentage. Turnitin simply identifies where text overlaps with existing content in its databases—it does not make a judgment about academic integrity [2]. Instructors are trained to review matches in context, seeing quotation marks and citations as markers of proper academic practice rather than violations.
What Does Turnitin's Similarity Report Show for Properly Cited Sources?
The Similarity Report provides a detailed breakdown of every text match, including those from properly cited sources. Each match is color-coded and linked directly to the original source material, allowing instructors and students to see exactly where text originated and whether it was properly attributed [3]. The report calculates an overall similarity percentage that represents the proportion of the paper matching existing sources—this includes properly cited quotes, paraphrased content, and any unacknowledged copying alike. However, instructors can apply multiple filters simultaneously, excluding quotes, bibliography entries, and small matches (such as common phrases under a set word count) to focus on the most pedagogically significant similarities [3].
This filtering capability means a paper with extensive direct quotations may show a higher raw similarity score, but after applying exclusion filters, the percentage can drop significantly. Understanding this distinction is crucial: a high similarity score does not automatically signal plagiarism—it simply reflects the total amount of text that matches other sources, whether properly cited or not. Turnitin's report is a tool for investigation, not a verdict, and educators are trained to evaluate each match within the broader context of the student's writing.
Can You Preview Your Turnitin Similarity and AI Report Before Submitting?
Turnitin does not offer students a built-in feature to preview their similarity or AI report before the final submission to an instructor's assignment. If your institution provides Turnitin Draft Coach, you can run checks within Google Docs or Microsoft Word, but this feature is not universally available and depends on institutional licensing [4]. Some instructors enable assignment resubmissions, allowing you to upload drafts and see reports before the final due date, but this entirely depends on individual assignment settings [4].
Because of these limitations, many students turn to third-party services that deliver real Turnitin similarity and AI reports before the official submission, giving them the opportunity to review their quoted text, fix citation issues, and adjust their work proactively. Being able to preview your report beforehand is especially valuable when you have included direct quotes—you can verify that your properly cited quotations are not causing an unexpectedly high similarity percentage and make any necessary adjustments before your instructor sees the final version.
Before you submit your final paper to your instructor, wouldn't it be reassuring to see exactly how Turnitin will score your similarity and AI writing reports? At turnitin0, you can upload your draft and receive your official-style Turnitin AI and similarity report within minutes, giving you full visibility into how your quotes and citations appear before your instructor ever sees them.

FAQ
Does Turnitin flag properly cited quotes as plagiarism?
No. Turnitin identifies text matches, but it does not label them as plagiarism. Properly cited quotes with quotation marks and attributions are shown as matches in the similarity report, and your instructor evaluates those matches in context. Turnitin's role is to highlight matching text, not to determine academic misconduct [1].
Can I exclude my quotes from my own similarity report?
No, students cannot apply exclusion filters to their own similarity reports. Only instructors and administrators can enable the "Exclude Quotes" and "Exclude Bibliography" filters within their Turnitin account settings. This is why previewing your report before submission is so valuable—you can see what your instructor will see with their specific filter configuration [2].
Will my similarity score be lower if I use fewer quotes?
Generally, yes. Since quotes represent text that matches existing sources, reducing the number of direct quotes and paraphrasing instead can lower your raw similarity score. However, proper academic quotation is a legitimate and important part of scholarly writing, so you should prioritize correct citation practices over chasing a lower percentage [3].
How can I check my Turnitin report before submitting to my instructor?
If your institution does not offer Draft Coach or assignment resubmissions, you can use services like turnitin0.com to upload your paper and receive a real Turnitin similarity and AI report before your official submission, giving you peace of mind about how your quotes and citations appear [4].
What is the difference between a quoted match and a plagiarized match in Turnitin?
A quoted match appears with quotation marks and a citation linking to the original source. A plagiarized match lacks proper attribution—the text matches an existing source but is presented as the student's own work. Turnitin does not automatically distinguish between these; it highlights all matches, and the instructor reviews the context to determine academic integrity [1][3].
