By what date should 11s be changed to 12L after graduations?

The requirement to change the 11s to 12Ls after graduations is set to ensure that all personnel are accurately classified and assigned to their appropriate roles within a timely manner. The date specified for this change is September 1, which is the day following the conclusion of the summer graduation period for many recruits. This alignment ensures that as new personnel transition from one classification to another, the Navy maintains an organized and efficient system for tracking both current and future assignments.

This date represents a standard practice within the Navy to help maintain clarity in personnel records, ensuring that as new sailors graduate, their assignments are updated immediately to reflect their new roles. This helps avoid confusion and keeps the staffing process seamless. Proper adherence to this timeline is critical for operational readiness and effective resource management within the Navy.
