Direct Answer - On a Turnitin AI writing report, % means the predicted percentage of AI-generated text in the document is below 20%. Turnitin deliberately displays a % symbol instead of a single-digit percentage (such as 5% or 12%) to avoid giving a false sense of precision for very low scores. This display convention applies to any score between 1% and 19%; the only explicit low numeric value a user sees is 0% [1]. The *% notation signals to instructors that while some text may have been flagged, the overall AI content prediction remains below the reporting threshold.
What Does the Asterisk Percentage (*%) Indicate on a Turnitin AI Writing Report?
The asterisk percentage (*%) on a Turnitin AI writing report indicates that the AI detection model has predicted between 1% and 19% of the document was generated by AI tools. This score band is distinct from a 0% score (no AI text detected) and from higher percentages (20% and above) that are displayed as exact numbers [2].
Turnitin's AI detection model analyzes submitted text by breaking it into segments of roughly a few hundred words and scoring each sentence between 0 and 1. An average score across all segments generates the overall prediction. When this average falls below the 20% threshold, the system replaces the exact percentage with *% to communicate that while some AI characteristics were observed, the signal is not strong enough to report with numerical precision [1].
It is important to understand that % does not mean "no AI was detected." Rather, it means the detected AI patterns are below the threshold at which Turnitin reports a specific number. The report still highlights individual sentences that the model flagged as potentially AI-generated, allowing instructors to review those segments even when the overall indicator shows % [3].
How Does Turnitin Determine Whether to Display *% Versus a Specific Percentage?
Turnitin applies a multi-tier scoring system with clearly defined thresholds. The AI writing detection indicator displays five distinct score bands: 0% (gray indicator), *% (gray/blue indicator, representing 1–19%), 20–40% (blue/yellow indicator), 40–60% (yellow/orange indicator), 60–80% (orange indicator), and 80–100% (red indicator) [2].
The 20% threshold serves as the critical boundary for *% display. This threshold is not arbitrary—it reflects Turnitin's confidence modeling. When the model predicts less than 20% AI-generated content, the signal-to-noise ratio is considered too low to assign a precise number. Displaying a number like 7% or 14% could misleadingly suggest a level of measurement accuracy that the model does not possess at those low levels [3].
Turnitin trained its detection model on a representative sample of both AI-generated and authentic academic writing across geographies and subject areas. The model's false positive rate is maintained below 1% for documents with more than 20% AI content. Below that threshold, the *% notation ensures instructors interpret the score as a broad indicator rather than an exact measurement [1].
Can You Get a *% AI Score on Your Own Paper Using Turnitin Before Submitting?
Under standard institutional Turnitin setups, students cannot independently check their papers for AI writing scores before submission. The AI writing detection indicator is only visible to instructors and administrators, not to students submitting through their institution's learning management system [4].
However, understanding your AI writing score—including whether it falls into the % range—before submitting to your instructor can be valuable. If your paper receives a % score, it means the AI detection model found minimal AI-generated content, which is generally a favorable outcome. If it shows a higher percentage, you can review the highlighted sections to understand what triggered the model's prediction [3].
Turnitin0.com offers a practical solution for students who want to preview their Turnitin AI report before submitting to an instructor. By uploading your document, you can see the exact same AI writing report that your instructor would see—including the score indicator, *% notation, and highlighted segments—allowing you to assess your paper's AI detection status in advance [4]. This gives you the opportunity to make adjustments or gather additional context before the final submission reaches your professor's dashboard.
Turnitin0.com provides students with authentic Turnitin AI and Similarity reports that mirror what instructors see in their academic systems. Whether your goal is to confirm a favorable *% score or investigate flagged sections, you can upload your paper and receive a complete report within minutes.

FAQ
Is *% the same as 0% on a Turnitin AI report?
No. % and 0% are two distinct indicators. A 0% score means the AI detection model predicts no AI-generated text was found in the document. A % score means the model found some AI characteristics, but the overall prediction is below the 20% reporting threshold [1].
Can instructors see exactly what percentage *% represents?
No. The *% display is the only information instructors receive for scores between 1% and 19%. Turnitin intentionally does not show the exact underlying percentage to prevent misinterpretation of low-confidence scores [2].
Does *% mean my paper will be flagged for AI misconduct?
Not necessarily. *% indicates minimal AI-pattern detection. Turnitin states clearly that the percentage should not be used as the sole basis for academic misconduct determinations. Instructors are advised to review highlighted segments and consider context before making any judgment [1].
Will a *% score change if I resubmit my paper?
Yes. If you make edits and resubmit through an assignment that allows resubmissions, Turnitin generates a new AI writing report. The % score may remain %, change to 0%, or increase to a higher percentage depending on the revised content [4].
How can I check my paper's AI score before submitting to my instructor?
Institutional Turnitin accounts do not allow students to independently run AI checks. Turnitin0.com fills this gap by letting you upload your document and receive an authentic Turnitin AI report—including the score indicator and highlighted segments—before you submit to your instructor's assignment [4].
