At this point, my child only has an IFSP but I can't understand why one wouldn't share the IEP with a teacher. Isn't the whole point of an IEP to help a child's education?
It kind of seems like you don't trust the preschool teacher, or her professionalism or training. I can see how that would be insulting to an early education professional.
Will you also refuse to show the IEP to his kindergarten teacher?
