CITI: Required Training in Ethical Human Subjects Research

The University of Denver uses the Collaborative Institutional Training Initiative (CITI) Program to provide the required training for all faculty, staff and student investigators.

All investigators, faculty sponsors, and members of the research team who are conducting human subjects research at the University of Denver are required to complete an education program and become "certified" in human subjects protections. These training modules must be completed before IRB approval will be issued.

Transferring Training from Another Institution
Please note: If you have completed CITI training affiliated with another institution, DU will not have access to those records. Investigators must affiliate their training records with the University of Denver in order for the IRB staff to validate the appropriate training has been completed.

Completing a Refresher Course
If you have already completed a required CITI course (valid for 4 years) and you were informed your certificate was going to expire soon, you may complete a refresher course. DU recognizes valid CITI training for four (4) years from the completion date. After four years, you will be informed that your certificate will expire, and a refresher course is offered to maintain credentials.
