Foundation Years (FY) have proliferated within UK Higher Education in recent years, and their benefits and successes have been well documented (e.g. the enhancement of opportunities for underrepresented students, second-chance education, skills and confidence enhancement, and a pipeline into STEM. However, when managed centrally, their implementation can be a contentious site of interdisciplinary unease and 'mutual suspicion' and as much as a fruitful avenue for innovative collaboration. One of the key issues is the question of how to embed academic skills/literacies development within a meaningful, 'integrated', interdisciplinary context effectively whilst utilising expertise from both academic departments and learning development/skills teams, and thus navigating disparate disciplinary agendas, communities of practice and strategic priorities. This paper reports on how this complex terrain was navigated at Royal Holloway, University of London, to successfully embed academic skills (using Universal Design for Learning pedagogy) into an academically authentic, inclusive, interdisciplinary 'Global Perspectives and Academic Practice' unit that facilitated student integration into academic departments. Whilst we report on how the programme led to higher than sector average attainment, retention and progression (the EE described it as a 'TEF Gold offering'), we critically analyse the challenges of embedding and aligning such provision within the communities of practice of a research-intensive institution. Throughout, we suggest ways forward at both practical and strategic levels to ensure the immense potential of integrated academic literacies development within FYs can be realised.
