This paper shares Oxfam GB’s experience of developing an approach to measuring women’s empowerment over the course of five years, for use in its series of Effectiveness Reviews. Oxfam’s aim is for this to be an easy and practical guide which shares experience and lessons learned in order to support other evaluators and practitioners who seek to pin down this ‘hard-to-measure’ concept. The hope is that the reader will make use of the measurement tools presented in this paper as guiding instruments that can be adapted to their needs.
