When did PLDC first become a mandatory prerequisite for promotion to Staff Sergeant?

The correct timing for when the Primary Leadership Development Course (PLDC) became a mandatory prerequisite for promotion to Staff Sergeant is in 1986. This policy change was significant in the Army's approach to leadership development, reflecting a growing recognition of the importance of effective leadership and management skills among non-commissioned officers.

Prior to this, promotion eligibility was based on time in service and time in grade, but the implementation of PLDC as a requirement emphasized the necessity for soldiers to possess not only experience but also the training to lead. This shift aimed at improving overall unit effectiveness by ensuring that leaders were better prepared for the responsibilities that accompany higher ranks.

In summary, the establishment of PLDC as a mandatory requirement in 1986 marked a turning point in the Army's commitment to fostering competent leadership among its non-commissioned officers, directly impacting the promotion process to Staff Sergeant.
