Testimonials

Turnitin Promotes Responsibility & Academic Integrity

“I love how it is used as a teaching tool rather than simply as a way to catch cheating students. My students understand that the responsibility is on them to avoid problems rather than for me to catch them. Students seem to be plagiarizing less and less, at least by copying and pasting from the Internet.”

2-Year College Writing Instructor


PeerMark Engages Everyone Through Collaboration and Feedback

PeerMark “allows me to deliver the considerable cognitive benefits of the peer review experience to my introductory class of 1,000 students. Only this brilliant tool allows me to do so without being swamped by administrative overhead.”

Prof. John Mitterer, Brock University

(Recipient of the Brock Distinguished Teaching Award)


GradeMark Saves Time

“My teachers feel that GradeMark is a tremendous time saver, saving around 30% of their time by grading and commenting on papers online.”

Walter Loblein Principal, Chatfield Senior High

“Students are happy to have their papers back in about a week, instead of two or three weeks it takes without Turnitin. I can take my laptop to the coffee shop, drink a coffee and grade papers without carrying around a huge stack of papers.”

Danielle Kulawiak, Language Arts Teacher
Mt. Olive High School, Flanders, New Jersey

Company History

biochemist

iParadigms started in 1996, when a group of researchers at UC Berkeley created software to monitor the recycling of research papers in their large, undergraduate classes. Encouraged by a high level of interest from their peers, they assembled a team of teachers, mathematicians, and computer scientists to form Plagiarism.org, the world's first internet-based plagiarism detection service.

By late 1998, Plagiarism.org had become the center of international media attention. The organization was featured in several major media venues, including Good Morning America, ABC World News Tonight, and the New York Times. Since then, iParadigms has continued to grow, becoming the world’s most widely used and trusted resource for detecting plagiarism and checking text for originality.
