Most public school systems are ill equipped to handle special needs students, especially those with behavior disorders, and quite frankly rarely have the students best interest in mind. There are some schools districts that don't want to lose out on funding by transferring the student to a specialty school, so they cobble together an in-house program. On the flip side, you have some schools that don't need to worry about the budget impact, and quickly send the student out of the district to protect the reputation of the school.
