This paper was developed to help guide CARE’s leadership model for girls in Power Within. It provides a literature review of definitions and approaches to girls’ education and leadership development. In addition to the literature review, expert informant interviews were conducted to develop a working definition of leadership and identify leadership competencies, and the findings are presented. Finally, this paper outlines the process of reflection that was undertaken once a definition of leadership for young adolescent girls had been developed. Using CARE’s gender empowerment framework to develop a theory of change, a girl’s leadership model was developed that values the role primary school education has in a girls’ life at this age, as well as her ability to interact in structured activities that build her leadership skills.
