CUClickers / iClickers

Last Updated: 07/08/2020

For Fall 2020, OIT recommends instructors use iClicker Cloud and students create an iClicker Reef account. Students will still need to purchase an iClicker from the bookstore for in-person courses using Clickers, and will need to link their iClicker to their Reef account, as well as register for their courses via Reef and link those courses to Canvas.

iClicker Cloud

iClicker Cloud is a polling software, like iClicker Classic, that enables students to participate in classes and answer questions provided by instructors. iClicker Cloud can also be used to poll both remote students, as well as students in the classroom. It integrates with Canvas: rosters can be downloaded and grades can be uploaded with ease. The software is free for instructors to use, and works with student iClickers as well as a student application called Reef.

iClicker Classic will be phased out during academic year 2020-21. iClicker Cloud provides a better user experience for faculty and students, and can be adapted to our changing educational environment.

iClicker Reef

iClicker Reef is a learning software that students can use in conjunction with an iClicker remote to answer questions in class and review those questions outside of class. It can also be used in remote learning situations, as an app on a phone or tablet, or via a web browser. iClicker Reef’s remote polling feature is free for students to use for University of Colorado Boulder classes through Fall 2020. Additionally, Reef will continue to be free to use with iClicker remotes.


  • Integrates with learning management system gradebooks.
  • Base stations are available in classrooms and large lecture halls with more than 40 seats or can be checked out from the Norlin Library circulation desk for use in rooms where not already deployed.
  • Students register iClicker remotes with their IdentiKeys enabling instructors to gather accurate data on responses.
  • Improves student learning when used according to best practices.
  • Most departmental rooms have bases and frequencies, and OIT will deploy a base to any room with greater than 40 seats upon request.


iClicker infrastructure is provided as a common-good to the campus which means there is no direct cost to you or your department. Student iClicker remotes are available for purchase at the CU Bookstore.
