The National Disability Insurance Scheme (NDIS) constitutes a major policy reform for Australian people with disabilities. Despite its ten-year implementation, little is known about the characteristics of the workforce delivering Australia's NDIS early childhood intervention services (ECI). The present study sought to identify the range of skills, knowledge, and experience of ECI professionals as listed in recruitment advertisements, and their alignment with best practice guidelines. Provider data were extracted from 246 advertisements for ECI roles over a 5-month period and assigned into various categories. Interrater reliability was determined by randomly selecting 65 of the 246 of the advertisements, which were coded independently by two researchers and assigned to service provider categories. Significant changes have occurred in the qualities of professionals providing ECI services under the NDIS, and their adherence to best practice guidelines. The limited emphasis on best practice in the recruitment process may result in an ECI workforce that is not well equipped to deliver specialised and inclusive support to young children with disabilities and their families.
