Mentorship is an important development process with individual and institutional benefits. Few postsecondary institutions offer faculty mentorship programs, despite their benefits for women and underrepresented groups and utility in promoting effective institutional leadership. In order to develop sustainable mentoring programs in diverse postsecondary contexts, core principles ought to be considered and constructed. One of these key considerations is ethics in mentorship. I argue that ethical mentorship necessitates a purposeful ethic of care within a framework of sustainable leadership that connects the potential of women's mentorship and the reality of unfulfilled mentoring relationships. An ethic of care constructed as a leadership paradigm is a purposeful way forward to ethical mentorship in postsecondary contexts and, more specifically, in a Middle Eastern women's university built on Islamic principles with culturally and historically relevant ways of knowing. Through analysis of a specific postsecondary context, implications are offered for meaningful and culturally appropriate mentorship for any postsecondary context.
