An investigation into the gender diversity gap in UK computer science higher education, focusing on identifying and evaluating policy measures that could mitigate this disparity. It will use a qualitative system dynamics approach to map the interrelated factors influencing female participation, including recruitment, retention, and progression, through causal loop diagrams. The research will draw on academic literature, national statistics, and institutional policy documents to identify key feedback loops and leverage points. The aim is to produce a policy roadmap that offers evidence-based, systemic recommendations for universities and policymakers to improve gender equity in computing education.
