Eating disorders, which encompass a broad spectrum of diagnoses, typically emerge in adolescence or young adulthood. This chapter focuses on eating or food-related disorders and malnutrition in children and adolescents. The chapter provides a general description of eating disorders in children and adolescents, assessment and treatment considerations, and resources for school-based clinicians who work with children and adolescents diagnosed with an eating disorder. Information about common school-related concerns, such as cognitive difficulties, frequent school absences, nutritional intake, and engagement in physical activities, is included, with specific strategies for the school-based professional to adopt when working with students with eating disorders. The chapter concludes with a list of helpful resources and a framework for guiding the development of an individualized education plan or 504 plan for students who need additional educational accommodations or interventions.
