The Gulf area is massive, so it helps to specify where you are living. We don't really provide info on KSA, and as the forum is entitled Dubai & UAE that is where our advice is focused. To attend school in the UAE, a child must be resident here.
Believe me thats not special needs.
According to Doctors now a days any kid who is hyper or disobedient(sp) is told they are add or adhd. Just make sure your kid takes his meds and put him in any school. If you say anything about add or adhd they will tell you no go to another school. As private schools can pick and chose what kids they will accept. Public school have to take any child. I know all this is crappy but thats the only way to deal with schools here in dubai.
