What age are most ADHD diagnoses made?

Most ADHD diagnoses are typically made during early elementary school. This timing is crucial because symptoms of ADHD often become apparent when a child starts school and is expected to begin structured activities that require focused attention, impulse control, and organization. In early elementary school, educators and parents may notice these behaviors, which do not align with developmental expectations for children in that age group.

Furthermore, standardized evaluations and monitoring of a child's behavior in different settings—such as at home and in school—are essential components of the diagnostic process, leading to identification during these early years. Early identification is critical for effective intervention, which can help manage ADHD symptoms and improve the child's academic and social outcomes.
