To direct the Under Secretary of Defense for Personnel and Readiness to conduct a study on certain grace periods under the Transition Assistance Program of the Department of Defense.

HR 6557 requires the Under Secretary of Defense for Personnel and Readiness to study grace periods under the Department of Defense's Transition Assistance Program (TAP), which helps service members transition to civilian careers. The study must assess how unit tasking affects service members' ability to participate in TAP, review current practices across military branches, analyze challenges in balancing duties with TAP requirements, and examine grace periods for unplanned absences like deployments. The Under Secretary must submit a report to Congress within one year, including findings, recommendations for reforming grace periods, and a plan for implementation if changes are proposed. This bill directly affects service members participating in TAP (referred to as "covered members") during their transition period.
