Equitable access to STEM pathways has been a core component of our work for almost 20 years. In 2004, we were part of an NIH-funded research project that allows us to do a deep dive into the factors associated with success of under-represented students in STEM at three institutions.  This work helped us appreciate the inter-relationship and consequences of programmatic support mechanisms (i.e., pedagogy, academic support, experiential opportunities - particularly research, career guidance, advising, mentoring, and financial). This framework has become embedded in our evaluation and research work in support of over 60 projects at 25 institutions. Increasingly, this work has focused on broadening participation in Computer Science pathways, particularly through our association with ECEP and as leaders of RPPforCS.
