Despite legislative and policy mechanisms that promote inclusion in education for children with disabilities, many students still experience exclusion from the education setting. For example, autistic children are more likely than their neurotypical counterparts to be expelled or suspended from school or to refuse to attend school on an ongoing basis. This situation gives rise to various challenges for their parents. This discursive paper synthesizes current knowledge on school exclusion involving autistic children, including the causes and consequences of exclusionary practices. The paper also considers the negative impacts of these exclusionary practices on the emotional and psychological well-being of parents and caregivers. Mental health nurses who understand the issues related to school exclusion can better support the educational, social, and developmental needs of autistic children and the mental health needs of parents or caregivers.
