There is another area of the curriculum where barriers can exist to full inclusion.
It typically receives less attention, yet is just as important. I'm talking about the "hidden" or social curriculum that is the by-product of a school's education program. This social curriculum conveys the values, belief systems, and expectations of behavior in the school setting.
This social curriculum is not "hidden" in an inclusive school. It's actually quite the opposite - with as much attention given to the social development of students as there is academic. Teachers give explicit instruction in social inclusion, model socially inclusive behavior, provide socially inclusive opportunities for students, and expect that all students will adhere to an inclusive belief system.
