Betty, while your solution to a child who is distracted in class is a possibility, perhaps starting with simple solutions might save the school time and money.
Why not first sit down with your child's teacher and discuss what the teacher observes in the classroom. Then, ask the teacher to give you a behavior contract that you and your child could live with, setting out exact expectations. Discuss the contract with your child being sure to let him (yes, they're mostly boys) know that you are in 100% agreement with the contract and his teacher. Sign and discuss the contract daily with your child, rewarding a perfect day and taking privileges when they fail to live up to the contract. Keep in weekly contact with his teacher, tweaking the behavior contract when necessary. The first few weeks may be a struggle, but if you and the teacher are consistent, the child usually adjusts his behavior accordingly.
I would also include the principal in on the contract, and weekly ask him to speak to your child about his work and deportment.You may also want to schedule an appointment with his pediatrician to determine if there are any medical reasons why the child is unable to attend appropriately.
If that fails, ask your child's teacher to set up a student study team meeting to then determine the next course of action, which may include an individual education plan.
