Objective: The objective of the study is to describe the extent to which students with ADHD received school-based intervention services and identify demographic, diagnostic, and impairment-related variables that are associated with service receipt in a large, nationally drawn sample. Method: Parent-reported data were obtained for 2,495 children with ADHD aged 4 to 17 years from the National Survey of the Diagnosis and Treatment of ADHD and Tourette Syndrome (NS-DATA). Results: The majority (69.3%) of students with ADHD currently receive one or more school services. Educational support (62.3%) was nearly twice as prevalent as classroom behavior management (32.0%). More than 3 times as many students with ADHD had an individualized education program (IEP; 42.9%) as a Section 504 plan (13.6%). Conclusion: At least one in five students with ADHD do not receive school services despite experiencing significant academic and social impairment, a gap that is particularly evident for adolescents and youth from non–English-speaking and/or lower income families.
