AD/HD (Attention-Deficit/Hyperactivity Disorder) is characterized by hyperactivity, impulsivity, and/or inattention.

There is no medical test for AD/HD. A medical doctor, psychologist, or other trained clinician can make a diagnosis after a thorough evaluation that includes interviews with parents, a medical history, and observations of behavior. Typically, AD/HD is diagnosed only if symptoms first appeared before age seven; have persisted for at least six months; occur in two or more settings; negatively impact social, academic, or occupational functioning; and cannot be accounted for by another disability.

Some students with AD/HD will need accommodations to succeed. For information on accommodations, see What are typical accommodations for a high school student with AD/HD?
