Leadership Identity Development Among Aspiring Women Leaders In Higher Education: A Phenomenological Study Of Formal Mentoring, Malia E. Roberts

Dissertations

Men have held the majority of presidencies, vice-presidencies, deanships, and other top administrative positions on college campuses since 1950 (Parker, 2015). The disproportionately low representation of women holding leadership roles in higher education is even more urgent considering few women ever reach the senior most leadership levels (Hannum et al., 2015). As such, the American Council on Education not only identified the need to increase the presence of women in leadership positions and to cultivate a pipeline of future leaders, but also the need to provide formal leadership training opportunities for women (Howard & Gagliardi, 2018).
