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).

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%).

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.
