Intellectual disability commonly co-occurs with autism spectrum disorder; however, the nature of unmet health care needs and health care quality in youth with autism spectrum disorder and intellectual disability…

Science content remains a commonly overlooked academic content area for students with severe disabilities, including ASD and ID, despite recent research. The purpose of this study was to evaluate the effects of systematic instruction, such as prompting and fading techniques, implemented during whole-group science instruction for students with both…

In the current investigation, we reviewed the literature on mand training for individuals with intellectual and developmental disabilities (IDD) in schools. Ninety-three studies met our inclusion criteria including 225 individual participants. Data were extracted related to participant demographics (e.g., age, disability, response form) and study…

There is on-going debate about whether mainstream education is desirable for children with profound and multiple learning difficulties (PMLD). Whilst some hold that 'inclusion' is a human right, and that interaction with mainstream peers leads to socio-cognitive gains, others argue that profoundly disabled learners require developmental curricular…
