F90

Restless in one classroom only

A 6-year-old is reported by his teacher to be constantly out of his seat, unable to wait his turn, and easily distracted in an unusually crowded, noisy classroom of 40 children with one teacher. His parents report no such pattern at home, and his weekend football coach, who sees him in a smaller group, also reports no difficulty with attention or sitting still.
