Behavior Intervention Plan

Since the school keeps denying services to my daughter, I now have another idea to get her the help she desperately needs. Thanks to a suggestion from a friend, I am requesting the school psychologist conduct an evaluation, observing her behavior (the scratching/skin picking) to determine the antecedents, causes, whatever, and develop a Behavior Intervention Plan to correct the behavior. Usually, I believe a BIP is used for problem behaviors such as hitting, kicking, biting, tantrums... but this is still technically a behavior that is causing her injury, so hopefully this will cover it, since nothing else does. They refuse to even evaluate her for OT, stating that OT can not be a stand alone service, so unless she is already receiving special education services, which she is not, they can not do OT. We just had a private evaluation and will get the results next Friday. So, cross your fingers that this request for a BIP works, and if you happen to know anything about the process (I believe it is called a Functional Behavior Assessment, which leads to the development of a BIP), please share! THanks!
