Introduction Translational research organisations (TROs) are a core component of the UK's expanding research base. Equity of career opportunity is key to ensuring a diverse and internationally competitive workforce. The UK now requires TROs to demonstrate how they are supporting gender equity. Yet, the evidence base for documenting such efforts is sparse. This study is designed to inform the acceleration of women's advancement and leadership in two of the UK's leading TROs—the National Institute for Health Research (NIHR) Biomedical Research Centres (BRCs) in Oxford and London—through the development, application and dissemination of a conceptual framework and measurement tool.

Methods and analysis A cross-sectional retrospective evaluation. A conceptual framework with markers of achievement and corresponding candidate metrics has been specifically designed for this study based on an adapted balanced scorecard approach. It will be refined with an online stakeholder consultation and semistructured interviews to test the face validity and explore practices and mechanisms that influence gender equity in the given settings. Data will be collected via the relevant administrative databases. A comparison of two funding periods (2007–2012 and 2012–2017) will be carried out.

Ethics and dissemination The University of Oxford Clinical Trials and Research Governance Team and the Research and Development Governance Team of Guy's and St Thomas’ National Health Service (NHS) Foundation Trust reviewed the study and deemed it exempt from full ethics review. The results of the study will be used to inform prospective planning and monitoring within the participating NIHR BRCs with a view to accelerating women's advancement and leadership. Both the results of the study and its methodology will be further disseminated to academics and practitioners through the networks of collaborating TROs, relevant conferences and articles in peer-reviewed journals.
