What is the perfect Turnitin score?

There's no single "perfect" Turnitin score, as acceptable percentages vary by institution, instructor, and assignment type, but scores below 15-20% are often ideal for essays, while lower is better for research papers; the key isn't the number but the Similarity Report's breakdown, which shows if flagged text is properly cited, paraphrased, or actual plagiarism. A high score isn't always plagiarism, and a low score isn't always original, so focus on your own writing and proper citation.
