Q: My 9-year-old son has severe ADHD. He has done fine academically in public school. (He just finished third grade.) He's on medication and has an Individualized Education Program (IEP), but he still struggles terribly with disruptive behavior in the classroom and with rigidity. (For example, he's always arguing about rule violations for whatever schoolyard game.) He has no friends who invite him to do things. We're considering a special school, and his psychiatrist and therapist see pros and cons to staying mainstream vs. going private.
