Teachers Guide to ADHD in the Classroom
ADHD Behavior and Serious Impairment
It’s important to keep in mind that not every high-energy or impulsive child has ADHD. Children are diagnosed with ADHD only if they demonstrate these symptoms so often that they are causing real difficulty in at least two settings — i.e., at school and at home. And the pattern that’s causing them serious impairment must persist for at least six months.
