This study aims to explore the perspectives of resource room teachers (RRTs) on their role transformation from regular education teachers to special educators and its influencing factors. Semistructured interviews were conducted with 10 RRTs from inclusive education schools in Beijing, China. This study found that the RRTs have experienced three stages of role transformation moving from confusion by the new job to conflict among multiple expectations and then to being professionalised as special educators with self-determination. They struggled with multiple roles, felt marginalised and deprofessionalised, and were dominated by a categorical perspective serving students with special educational needs. Moreover, clearly authorised full-time positions, professionalisation, administrative support, and attitudes towards inclusive education were found to be key determinants in RRTs' successful role transformation. The present study concludes that RRTs should be empowered with clear expectations of their roles and responsibilities to lead inclusive education practices in schools and guarantee a stable professional status via sustainable training.
