JDAMIS & The Joint Duty Assignment List (JDAL)
The Joint Duty Assignment Management Information System (JDAMIS) is an automated management information system and database maintained by the Defense Manpower Data Center (DMDC) and updated by the Joint Staff, Military Services, and joint organizations. JDAMIS serves as the permanent system of record for all Joint Officer Management (JOM) related matters.
The position management file within JDAMIS constitutes the official Joint Duty Assignment List (JDAL). This list is formally approved by the Under Secretary of War for Personnel and Readiness (USW(P&R)) and managed by the Joint Staff J-1. The JDAL is the official statement of current and historical joint positions and is modified only with USW(P&R) approval or other OSW-delegated authority.
JDAL Qualification Criteria
-
Paygrade Threshold: JDAL positions are strictly restricted to permanent, funded billets in the paygrades of O-4 (Major) and above.
-
Billet Preponderance: To be certified on the JDAL, the preponderance of a billet's day-to-day responsibilities must meet the statutory definition of "Joint Matters" (10 U.S.C. Section 668).
-
Drop-Off Protection: If an officer is occupying a billet that is de-certified from the JDAL during their tour, their joint credit is legally protected. The officer will receive full credit, provided they executed a valid check-in diary entry prior to the drop-off date. Backfills for that billet will not receive credit.
Statutory Definition of "Joint Matters" (10 U.S.C. 668)
To qualify for JDAL inclusion, billet responsibilities must relate directly to the achievement of unified action by multiple military forces in operations conducted across domains—including land, sea, air, space, or the information environment. This comprises:
-
National military strategy, strategic planning, and contingency planning.
-
Command and control of operations under unified command.
-
National security planning with other departments and agencies of the United States Government (interagency).
-
Combined operations with the military forces of allied nations.
Note: In this context, "multiple military forces" refers to forces involving participants from the U.S. Armed Forces alongside other federal departments/agencies, foreign military forces/agencies, or non-governmental entities.
Positions Categorically Excluded from the JDAL
Per DoDI 1300.19, certain assignments cannot be placed on the JDAL, regardless of their location or command. Officers in these roles may, however, proactively apply for E-JDA (Experience-Based) points via self-nomination if their individual duties meet the statutory threshold. Excluded Position Categories:
-
Student Assignments: Any assignment for joint education or joint training.
-
Instructors: All instructor positions, excluding faculty members directly responsible for preparing and presenting JPME Phase II curricula.
-
Fellowships & Internships: Assignments affiliated with educational, research, or degree-granting programs where the officer is not responsible for executing or implementing joint policy.
-
Intra-Departmental Roles: Assignments located entirely within an officer’s own Military Department.
-
Junior Officer Billets: All positions legally requiring the paygrade of O-3 and below.
-
Temporary Billets: Temporary, overage, or unfunded positions.
JDAL Visibility and Access
The JDAL is not publicly published or posted for general access due to high volatility (billets are constantly added, modified, or de-certified) and generic coding. Roughly half of the Marine Corps billets on the JDAL are generically coded as 8006 (Unrestricted Officer), 8007 (Unrestricted Ground Officer), or 7506 (Pilot/NFO). MMOA monitors do not know which specific occupational fields will be required to fill these billets until the Officer Staffing Goal Model is finalized.
