Calibrated Peer Review


Calibrated Peer Review
Integrate more frequent writing assignments and help students learn how to evaluate quality work
Calibrated Peer Review (CPR) is a web-based program that allows instructors to incorporate frequent writing assignments into their courses, regardless of class size, without increasing their grading workload. The CPR system does this by facilitating a peer review process where students give feedback and assign grades to their peers. The system manages the entire peer-review process, including assignment creation and submission, student reviewer training, and student input analysis. One of the main features of the system over others is that it incorporates a training component to help students learn to become competent reviewers and provide quality feedback to their peers. Instructors may create their own assignments in CPR or use CPR Central to share assignments with other CPR institutions.

All student data is stored on UBC servers. CPR was originally created by UCLA with the support of NSF funding. UBC pays a subscription fee to UCLA for the use of CPR.

How can Calibrated Peer Review help me?

CPR provides a mechanism to incorporate more frequent writing assignments into your course, regardless of class size. By helping students learn how to evaluate each other, it allows for increased opportunities for feedback on written work without increasing the grading workload for instructors and TAs. Writing assignments help students to practice higher-order skills such as synthesis, analysis, and evaluation. The peer review component helps students learn to think more critically about their own work and the work of their peers. The training component of the CPR system provides a useful mechanism to help students learn how to be effective evaluators.


  • Peer evaluation is most effective when students are given training to help them learn how to become effective reviewers. The CPR system incorporates a training phase into the process to help give students practice doing peer evaluations and feedback on how well the marks they give match up with an expert reviewer.
  • The CPR web site ( provides a community space and assignment library for instructors to share sample assignments across institutions.
  • The CPR system provides structured instructor training for assignment development and student training that help instructors to create more effective assignments and assessment criteria.


  • The CPR system is not integrated with Connect or UBC’s CWL authentication system. Faculty must submit a request for an account to be created. Students must create an account on UBC’s Calibrated Peer Review site (
  • The CPR system provides a fully structured process for peer evaluation which aids in effective implementation, but that may take more time than other systems to learn and set up.


  • All student data is hosted on UBC servers, however, the CPR system is currently not integrated with CWL authentication or Connect.


  • Look through the Calibrated Peer Review assignment library to find examples of how other instructors have used CPR in their courses.
  • Peer review assignments can be a helpful way for students to get feedback on their drafts before submitting a final version for instructors or TAs to mark.
