Work-integrated learning (WIL) has been suggested as a potentially beneficial addition to modern doctoral education. However, there is little research outlining the specificities of WIL aimed at PhD students. This paper explores the range of WIL opportunities available to PhD students through a review of secondary data. The findings indicate that WIL opportunities are non-homogenous and vary widely across their structure and implementation. Patterns emerge to indicate that WIL opportunities tend to be optional, paid, short-term, focused on horizontal learning development, and provide opportunities for boundary crossing outside of academia. These findings imply that WIL has the potential to complement doctoral education by providing opportunities to experience cross-sector or cross-discipline learning and development. However, higher education institutes might consider becoming more involved in the design and implementation of WIL for PhD students. Additional research is required to understand how WIL opportunities fit into doctoral education and to evaluate existing WIL opportunities.
