Canvas has a built-in Peer Review Feature that works well. Here’s a tutorial on how to create a Peer Review Assignment in Canvas, but you can find more resources about Peer Review in Instructure’s Guides.

QFT Tech Tip IconTech Tip: When setting up a Peer Review Assignment, some instructors use the Due Date (1) for the assignment will apply to students turning in their work. There is no function to assign a due date for students to review each other’s work. However, you can use the assignment availability (2) as the deadline for reviews. The assignment availability will make the assignment unavailable for all students. [See screenshot below.]
