Turnitin enables instructors and students to check the similarity of student work comparing submissions to other sources on the Internet and in Turnitin's extensive database. Additionally, instructors can directly mark-up student submissions - saving your frequently used comments in libraries of "quick marks" for improved work flow - as Turnitin integrates into your existing Blackboard Learn.

Why Should I use Turnitin?

  • Check for potential plagiarism
  • Drag and drop frequently used feedback comments
  • Leave voice comments
  • Grade by rubric 
Similarity Check

CSU Chico discontinued support for Peermark. According to the Turnitin Product Roadmap, they are “no longer making any changes” to the current PeerMark product. Their long term goal is to “replace PeerMark with a new tool that instructors and students can use with ease.”

Please contact a Technology and Learning Program consultant to discuss other peer review options, which include Google Docs, Blackboard Learn groups, etc.

Since students own the copyrights to their works (in most cases), Turnitin asks students for confirmation to submit a copy of their paper to Turnitin's repository.  Students opting out of this may need alternatives, such as: requiring a photocopy of the first page of all reference sources used, an annotated bibliography, and a one page paper reflecting on their research methodology.
