You are not failing. I had this same problem. My son, despite being smarter than any of the kids at these schools, got kicked out of 3 pre-schools. He even had a problem at the beginning of Kinder. He is now almost finished with kinder and is doing great! We chose to do play therapy with him to work on stress and anger management. My son freaks out in times of high stress, so we now work on self talk through stress and deep breathing. My son is quite intellegent and I think he just gets disinterested and likes to challange people. A ton of great parents with smart boys have issues like this. It is not you. You need to find a school that will challenge him and understand his needs. Explain everything in advance.
Good luck! It will work out!
