Logging on to the Electronic Periodic Health Assessment (ePHA) will require a CAC or registration and password.
Completing the PHA requires you to fill out approximately 25 pages of health information and takes 10-20 minutes. The value of this new Electronic PHA System over paper records is that once you complete the first time your answers are saved.
