Gender equality has made its way to the forefront of discussions across various sectors in the Canadian context. Yet the intentional inclusion of gender and other intersectional identity dimensions is just beginning to permeate the realities of performance measurement and evaluation practitioners, particularly those using program theory. There is a vast body of knowledge regarding the measurement of women’s empowerment, gradually declining availability of resources targeting the inclusion of gender in theory, and even less guidance on integrating gender in theory in the context of gendered programming. Similarly, coordinated efforts from multiple sectors have resulted in an abundance of theory regarding girls and women’s representation, recruitment, retention, and promotion within STEM (Science, Technology, Engineering, and Math) but less guidance on the measurement and evaluation in these areas. This article shares recent efforts to bridge the divide using theory knitting to develop a performance measurement framework addressing the decreasing representation of girls and women across the STEM “leaky pipeline” using the COM-B theory of change model.
