STEM leaders, deans and chairs who oversee three or more academic disciplines, tend to leave their posts at a fast pace. This can cause disruptions within an academic unit for both students and faculty. The purpose of this action research study was to investigate the rate of attrition among community college Science, Technology, Engineering and Mathematics (STEM) leaders within a state system and to propose an onboarding program to reduce attrition. Through an initial phase of research study participants, community college STEM leaders within a state system, shared their experiences transitioning to a STEM leadership position. The STEM deans and chairs focused on subjects including general leadership, middle management at community colleges, lack of training to support the transition from faculty to STEM leader, and issues specific to STEM leadership in the training program. Participants noted several reasons why STEM leaders are likely to leave their positions including issues with college hierarchy, the need to hold multitude of roles and responsibilities, and issues with the structure of the institution in relation to STEM. There was also an emphasis on the dean position and not being afforded the ability to teach in a purely administrative position as a reason one may not remain in the job. STEM-specific leadership issues highlighted included underprepared students and high cost of programming. A second phase of research tested a new onboarding program with current STEM leaders within the state system to determine its potential effectiveness for future leaders. Participants were asked to join three live sessions, answer surveys, and complete a one-on-one interview once the three sessions concluded. Assessing the results of the study, it was determined that this training could potentially be very helpful in aiding the onboarding of new community college STEM leaders.
