Direct answer
A plagiarism report is written in five parts: a header identifying the document and check date, a summary of the similarity score and AI writing score, a source-by-source match table, an interpretation section that classifies each match as quoted, paraphrased, common knowledge, or genuine overlap, and a conclusion with recommended actions. The report must reproduce the underlying data exactly — overall percentage, per-source percentages, and the excluded sections — because a similarity score is a measure of matching text volume, not a verdict on intent [1]. Write it as evidence a reader can audit, never as an accusation.
What Sections Should a Plagiarism Report Contain?
A plagiarism report is a structured document, and its sections should mirror the structure of the underlying similarity data rather than a narrative essay. Turnitin's report architecture separates the overall similarity index from the match overview and the full sources list, with each match tied to a specific source and a specific percentage contribution [2]. Your written report should preserve that separation: never blend the headline number into the same paragraph as the source breakdown, or a reader cannot tell which figure came from where. Start with identification details — author, document title, word count, submission date, and the tool and settings used for the check — because institutional settings change what is displayed and therefore what your numbers mean [3].
The second block is the summary: the overall similarity percentage, the AI writing percentage, and the date and time of the check. State the tool version and whether the repository was included, since a non-repository check and a standard institutional check are not comparable figures. If the AI indicator returns an asterisk instead of a number, record that exactly as displayed and explain that it represents a low-confidence signal below the tool's reporting threshold rather than a zero [1].
The third and most substantial block is the match table. List every source in descending order of contribution, and for each one record the source type (journal, book, web page, student paper), the percentage, the matched excerpt, and the page or paragraph location in your document. Turnitin ranks sources by contribution precisely so that the largest overlaps are addressed first [2]. A table forces you to account for every percentage point, which is what makes the report auditable.
The fourth block is a declaration of exclusions. If quotations, the bibliography, or small matches were filtered out of the headline figure, say so explicitly and give the filtered settings. Omitting that line is the single most common way a plagiarism report becomes misleading, because two reports of the same document can legitimately show different scores [3].
How Do You Interpret a Similarity Score Correctly in a Report?
Interpretation is where most plagiarism reports fail, because a similarity percentage answers "how much text matched" and not "did this author plagiarise." A high score can be produced entirely by correctly cited block quotations and a comprehensive reference list, while a low score can still conceal a single unattributed copied paragraph [3]. Your interpretation section should therefore classify each match rather than defend the total: mark it as properly quoted and cited, adequately paraphrased with citation, common knowledge that needs no citation, or unattributed overlap requiring correction.
Work from the excerpt, not the number. For each flagged passage, open the matched source, compare the wording side by side, and record whether quotation marks, a citation, or both are present. This is also why Turnitin frames the similarity report as a feedback instrument for revision rather than a disciplinary verdict — the report is designed to be read alongside the submitted document, match by match [4]. A report that lists sources without examining the actual wording has documented a number, not an originality finding.
Be explicit about what the score cannot tell you. It cannot detect intent, it cannot distinguish poor paraphrasing from deliberate copying, and it cannot see a citation that exists in a footnote the tool did not parse [1]. State those limits in one short paragraph so that anyone reading your report later understands its scope. If the document was checked with a different tool or different filters than your institution uses, note the discrepancy rather than silently reconciling it.
Finally, keep the AI writing score in its own subsection. Turnitin reports the AI writing indicator separately from the similarity index, and the two measure different things: similarity compares your text to a database of sources, while the AI indicator estimates how much text was likely generated by a model [4]. Conflating them in a single "plagiarism percentage" is a factual error that undermines the credibility of the whole report.
How Can You Get an Actual Turnitin Similarity and AI Report to Document Before You Submit?
You cannot write an accurate plagiarism report from a guess. You need the real report — the match overview, the ranked sources list, and the AI writing indicator — because those are the exact components your written report has to reproduce [1]. Reviewing matches before final submission is the intended use of the similarity report: it exists to support revision and to make citation problems visible while they can still be fixed [4].
Turnitin0 provides that pre-submission check. You upload a .docx, .pdf, or .txt file (English, 300–30,000 words, under 20 MB) and receive two downloadable PDFs in one order: a Turnitin AI detection report and a similarity/plagiarism report, formatted as instructors see them in their LMS. The check is non-repository, so your file is not added to Turnitin's student paper database and reports are not shared with third-party databases; you can delete files from your account. Turnaround is under 15 minutes in 98% of cases, with delivery guaranteed within 30 minutes. Turnitin0 is an independent service and is not affiliated with Turnitin, LLC.
With those PDFs in hand, the writing becomes mechanical rather than speculative. Copy the overall similarity percentage and the AI score verbatim into your summary block, transcribe the ranked source list into your match table, and record the filters that were applied. Where the AI indicator shows an asterisk rather than a percentage, note it as a low-confidence signal below the reporting threshold instead of recording a zero. Because the reports match the institutional format, the figures you document are the figures your institution will see, which is the whole point of writing the report in the first place.
A plagiarism report is only as trustworthy as the data behind it, and guessing at your score produces a document nobody can rely on. Turnitin0 gives you the genuine similarity and AI reports to work from — the same cover, score, flag list, and similarity summary your institution reads — so every figure in your write-up is sourced rather than assumed.

FAQ
Does a high similarity score automatically mean plagiarism?
No. The score measures the volume of matching text, and correctly cited quotations or a long reference list can raise it substantially [3]. Interpretation requires reading each matched excerpt, which is why a plagiarism report needs a classification section rather than a single number.
Should quoted and cited material be removed from the score?
Institutions commonly filter quotations and bibliography, but the settings vary, so two reports of the same document can show different figures [1]. If you filter anything, declare the exact settings in your report so the number is reproducible.
How is the AI writing score different from the similarity score?
Similarity compares your text against a database of sources, while the AI writing indicator estimates the likelihood that text was model-generated; Turnitin reports them separately [4]. They should never be combined into one combined "plagiarism percentage."
What does an asterisk instead of an AI percentage mean?
It indicates a low-confidence signal below the tool's reporting threshold rather than a confirmed zero. Record it exactly as displayed and explain the convention in your report [1].
Can I write a plagiarism report without running a check first?
Not accurately. The report must reproduce the overall score, the ranked source list, and the applied filters, all of which come from the actual similarity report [2]. Running the check first is what makes the write-up verifiable.
