The Defense Counterintelligence and Security Agency (DCSA) is extending the Joint Personnel Adjudication System (JPAS) to the Defense Information System for Security (DISS) transition period. Not all functionality required for full transition from JPAS has been established in DISS, and it will not be established in DISS on or before December 31, 2020. However, the eligibility records in DISS are reliable, based on consistent use of DISS to record adjudication results over the past two years and recurring data quality initiatives. Until further notice, users may continue to use JPAS while we validate functionality and ensure historical data has successfully transferred to DISS. DCSA remains committed to successful transitioning from JPAS to DISS. Since Oct. 1, 2020, DCSA has addressed functionality and data migration issues identified by DoD components and industry and continues resolving these concerns. DCSA will provide frequent updates to the user community. When required functionality is available and working properly in DISS, currently targeted for April, 2021, entities with corrected data will discontinue using JPAS.
