Increasing the proportion of culturally and linguistically diverse (CALD) health practitioners is identified as one strategy to address healthcare disparities that individuals from minority or under-represented backgrounds experience. However, professional and institutional cultures and structures are known to contribute to the challenges for CALD practitioners who work in dominant culture practice contexts. This scoping review used the theory of Legitimate Peripheral Participation to describe and interpret literature about the experiences of CALD health practitioners in view of informing strategies to increase their representation. A systematised search was conducted across four allied health, medicine and nursing databases. Following abstract and full text screening, articles which fit the inclusion criteria (n = 124) proceeded to data extraction. Categories relating to the experiences of practitioners were extracted, and three themes were identified that were subsequently theoretically interpreted: Discrimination, Consequences and Hierarchy. Discrimination functioned as a barrier to CALD practitioners being legitimised and able to participate equally in healthcare practice, retaining their position at the periphery of the practice community; Consequences reinforced this peripheral position and further impeded legitimation and participation; and Hierarchy was maintained through structures that reinforced and reproduced these barriers. The findings summarise how these barriers are reinforced through the intersections of professional and racial hierarchies, and highlight a need for strategies to address discrimination and structures that marginalise CALD practitioners’ identity, practices and participation in their health professional communities.
