Does Turnitin Detect Plagiarism? A Detailed Analysis

Can Turnitin Detect Plagiarism? Understanding Its Function

Turnitin is widely recognized as a plagiarism detection tool, but does it truly detect plagiarism? The short answer is no. Instead of directly identifying plagiarism, Turnitin scans submitted content for similarities against its extensive database of academic papers, journals, and previously submitted student work. The tool provides similarity scores and reports, helping educators determine whether a submission includes unoriginal content.

How Does Turnitin’s Similarity Report Work?

Turnitin generates a Similarity Report by comparing submitted content with its database. The system breaks the text into small segments and identifies matching phrases. The report highlights these similarities using different color codes:

• Blue: No matching text (0%)
• Green: Low similarity (1-24%)
• Yellow: Moderate similarity (25-49%)
• Orange: High similarity (50-74%)
• Red: Very high similarity (75-100%)

It is important to note that a high similarity score does not automatically indicate plagiarism. It is up to educators to analyze whether the highlighted content is properly cited or constitutes unintentional duplication.

Steps to Check for Similarity:
