All investigators participating in research sponsored by: 

• Department of Energy (DOE), 
• Public Health Service (PHS), or  
• PHS-like agencies (i.e., agencies that have adopted PHS regulatory requirements)  

are required to complete conflict of interest (COI) training PRIOR to engaging in such research and no less than once every 4 years thereafter.  

Princeton provides this training through the online Collaborative Institutional Training Initiative (CITI) Program. After an investigator completes the COI Basic Course (Stage 1), the CITI Program will notify the investigator to complete the COI Refresher Course (Stage 2) 30 days prior to COI training expiration. 

Follow these instructions for logging on and affiliating your CITI account with Princeton University.  

COI training for all named investigators must be completed and verified before spending is allowed on a PHS/DOE award. Training does not need to be completed before a PHS/DOE proposal is submitted, however it is in an investigator’s best interest to complete CITI COI training as soon as possible so that processing of the award is not delayed.
