In this workshop, we present evidence and look at why children with additional needs are at a greater risk of mental health difficulties, and how schools can promote mental health and wellbeing in children who have additional needs. The session considers how the KidsMatter framework guides schools through a whole-school approach that promotes a positive school community, develops children’s social and emotional skills, strengthens parents and carer engagement, and assists children experiencing difficulties. Key principles for supporting children with disabilities to participate and be included at school are discussed, along with key findings from the Ministerial Advisory Committee: Students with Disability (MAC:SWD) reports into KidsMatter and children with disability in primary schools and early childhood services.
