Within Science, Technology, Engineering, and Mathematics (STEM) careers fields, the representation of women remains at an inequitable level when compared to men and to women's representation in other professions. Given the current state of women representing 52% of the professional and management-related workforce (U.S. Bureau of Labor and Statistics, 2015), their representation at only 15% of employed engineers nationwide appears to be a problem. When considering the fact that recent graduation data show women earn over 19% of Bachelor's degrees in engineering each year, the low number becomes increasingly puzzling. What factors are contributing to this low number of women in engineering professions? One of the contributing factors is clearly women's choice of education and career paths. However, empirical literature suggests, after pursuing and entering the engineer profession, women often are victim to gender schema, cognitive bias, and an absence of family-friendly work policies, an insufficient number of female mentors, social exclusion, and other drivers potentially leading to their higher turnover rate compared to their male counterparts. This project looks within one military-related organization to uncover reasons for the low representation of female engineers. The combination of a mixed-methods approach to data collection and the Knowledge, Motivation, and Organization (KMO) framework developed by Clark and Estes (2008) for analysis is employed by this project. Comparison of the analysis results to widely accepted learning and motivation principles presented in the reviewed literature led to a proposal of research-based solutions to address the representation gap and ultimately increase women's representation in engineering and other STEM career fields.
