All new IRB applications submitted after February 1, 2019, will be submitted through Cayuse IRB. 

Cayuse Accounts

To access Cayuse, a user must have a Cayuse account. Accounts have been created for all TWU investigators, faculty advisors, and research team members on active studies. In order to add any TWU research team member, they must also have a Cayuse account. If an account needs to be established, an email should be sent to with the person’s name, TWU email address, and department. The IRB staff will then create an account in Cayuse. Please note that this process may take 1-2 days.


All users with a Cayuse account should be able to login to Cayuse IRB at using their TWU Portal account username and password (refer to the Cayuse Login Instructions for detailed information). After logging in, please select Cayuse IRB to begin working in the IRB system.
