What school system? In Calvert Co. there are schools that have BDP classrooms (behavior development program) where the students have to "earn" their way out, they are separated from the rest of the population, usually goes along with a Dr.'s diagonosis/IEP plan (individual education plan) that is develop by a team within the school system, ie: the vice principal, special education teachers, school psychologist, etc. There is also a behavior specialist for the county that the school can call to observe a child that they have concerns about and he helps the classroom teacher understand the child's issues and how to manage in the classroom until a determination is made that the child should be placed in a BDP classroom. All schools (I believe in any school system) should have a Pupil Services Worker who can help to coordinate county as well as school services, I would call the school that your nephew is enrolled in and start with the Guidance Counselor, then ask to speak with the Pupil Sevices Worker. Don't give up, it's a hard battle, but one worth fighting, and not too late at 5 years old. Good luck!
