I would say that, from my terrible experiences with a mainstream school system (I go to a school with people with behavioral problems/emotional problems, as I experienced moderate depression and have anxiety, though with both an imaginational as well as emotional overexitability, I'm starting to doubt it), you could talk to a pediatrician, or a specialist. But,in my opinion, what a parent thinks is slightly more valid, because you see your child every day, not just observe them like he's a wild animal.
