Random sampling method was utilized with a descriptive study design. Conner’s scale was administered to teachers to identify children exhibiting ADHD symptoms.

Results and conclusion : There is significant difference between teachers of Government, Private aided and Private unaided schools with respect to inattention, hyperactivity, impulsivity symptoms.
