Free to read on publisher website\ensuremath</b\ensuremath> Career development learning has a demonstrable positive impact on the graduate employability of higher education learners. This is particularly the case if it is integrated into the curriculum rather than experienced as an add-on or included in finite curriculum elements. However, integration of career development learning into curriculum is a significant and challenging undertaking in course design, and also in facilitation of learning experiences. Academics manage crowded curricula in their disciplinary areas, and many also have external course accreditation requirements to deal with that may not include career development elements. In many institutions there is mixed understanding of what career development learning entails, no clear top-level strategic support, and unprecedented numbers of enrolled students across digital and on-campus provision. This article explores challenges and opportunities in integrating career development learning into curriculum in higher education, and identifies effective strategies for doing so at institutional, school, and programmatic levels. It draws upon case studies comprising more than 30 interviews across nine universities in Australia and internationally, exploring how cross-disciplinary collaboration between career development practitioners, learning and curriculum designers, and academic units can be effective in enacting curricular career development learning at scale. The article suggests strategies for institutional leaders, academics, and careers practitioners in higher education insitutions at different stages in the curricular career development learning journey.
