JPAS (Joint Personnel Adjudication System) was the primary Department of Defense (DoD) database used to manage, track, and verify military and contractor security clearances until it was officially phased out. In March 2021, the DoD completely transitioned its personnel vetting data from JPAS to a centralized platform known as the Defense Information System for Security (DISS).
Understanding how JPAS operated—and how DISS functions now—is essential for any military member, civilian employee, or defense contractor navigating the clearance landscape. Core Functions of the Legacy JPAS
When it was active, JPAS served as the single “system of record” for the military vetting community. It was managed primarily through two subsystems:
JAMS (Joint Adjudication Management System): Used by Central Adjudication Facilities (CAFs) to log background investigation results and record final clearance decisions.
JCAVS (Joint Clearance and Access Verification System): Used daily by Facility Security Officers (FSOs) and military security managers to check eligibility, log non-disclosure agreements, and process “visit requests” for secure facilities. What is Inside a Security Clearance Record?
