Demystifying Turnitin: It's Not Just a Plagiarism Checker

How Turnitin Works
Turnitin compares your submission against a massive database of websites, books, journals, and other student papers. It highlights matches.
The Similarity Score
There is no 'magic number' for a safe score. A 0% score is suspicious (did you use no sources?), while 15% could be fine if it's all correctly quoted references. A 5% score could be plagiarism if it's a copied paragraph without citation.
Interpreting the Report
Look at the matches. Are they:
- Quotes? If cited correctly, this is fine.
- Bibliography? Matches here are expected.
- Common Phrases? 'The results of this study show...' will match. Ignore these.
- Blocks of Text? If you have a large block of highlighted text that isn't a quote, you need to paraphrase better.
Using it Formatively
Use the draft submission option if your university allows it. It helps you spot where your paraphrasing is too close to the original.
