Summary

ComPAIR is a free, open-source application for peer review in which students compare pairs of answers and provide feedback on both. Instructors can enable scores that respond to comparison performance and use those results to form later pairs. The project describes this approach as supporting richer feedback and deeper critical thinking. Separate student, instructor, and system administrator roles have different permissions. ComPAIR supports LTI login, course membership, and grade updates for LTI consumers. Learning analytics can be sent to a Learning Record Store through xAPI or Caliper, though both are disabled by default. Documented authentication options include username and password, CAS, SAML 2.0, and LTI. It is web-based and self-hosted; the README documents running it with Docker Compose and accessing it at localhost:8080. The default attachment upload limit is 250 MB, with PDF, audio, video, and image extensions allowed by default. ComPAIR is available to download, install, and use under the GPL-3.0 license, and is described as suitable for higher education and K-12 communities.
