Final answer:
Appointments for completing the DA Form 3355 should be scheduled by the BN HR in a timely manner, typically well in advance of the promotion board.
Step-by-step explanation:
The student's question pertains to the scheduling of appointments for Soldiers attending a promotion board to complete the DA Form 3355, which is the Promotion Point Worksheet used to determine a Soldier's eligibility for promotion in the U.S. Army. The BN HR (Battalion Human Resources) must schedule these appointments in a timely manner to ensure Soldiers have completed the necessary documentation before appearing before the promotion board. The specific timing for scheduling these appointments can vary according to the battalion's internal Standard Operating Procedures (SOP) and the scheduled date of the promotion board. Typically, appointments are scheduled well in advance of the board to allow ample time for the Soldier to review and verify the accuracy of the points awarded on the DA Form 3355.
