The traditional inclusive education categories of behavioural needs or mental illness are examined. Included are the concerns of students with diagnoses such as anxiety and depression according to the Diagnostic and Statistical Manual for Mental Disorder Fifth Edition (DSM-5), as well as students with behaviour disorders. Also included are the behavioural concerns of students with autism, intellectual disabilities, and attentional difficulties. The British Columbia Ministry of Education criteria for designation in the Behavioural Needs or Mental Illness categories are addressed. The course includes a critical review of literature, building on students’ extant knowledge and professional experience and an examination of current best practice in the areas addressed. Classroom intervention strategies are studied and are critically evaluated.
