If you are considering adopting a tool to aid in peer assessment in your course, here are some best practices:

  • Communicate with students about the values and purposes of peer review/assessment.
  • Consider students' workload. 2-3 assignments per semester has demonstrated a good fit.
  • Fewer points on the first assignment (students need time to learn the system with the first assignment).
  • Incorporate instructor-graded assignments after peer review assignments. Students can use these tools as opportunities to revise their work.

Keys to success

  • Develop specific rubric questions that help focus students' assessment process
  • Train students how to apply rubric criteria when they evaluate peers' work


Calibrated Peer Review (CPR) is a web-based application to incorporate more frequent writing assignments into your course. It is best used for generating reliable peer ratings that could be compatible with instructor ratings.
