Just to illustrate the cost to advanced students in an inclusion model - DD13 is in an 8th-grade USH class that the teacher describes as half honors students, half students with spectrum disorders of the ASD or ADHD variety. To say DD is getting almost nothing of value out of this class would be a significant understatement. She mostly tunes out of class activities and tries to get homework done for other classes without getting caught by the teacher. If it wasn't for the fact that she has a parent with an expertise in and passion for the subject, she'd be permanently turned off from it.
