There is a wide range of possible placements along the inclusive education spectrum. From segregated schools, to entirely inclusive placement with minimal "pullout," parents and educators have options to work with. Most children with diagnosed disabilities attend school somewhere along that spectrum. The only exception might be children qualified as extremely "medically fragile," who may be taught through home-based services due to their medical needs. Every child is an individual, and every educational programming solution will be different. Parents should be prepared to ask questions about their child's individualized education program (IEP), and the teacher should be prepared to answer those questions and provide ongoing resources and support for families.
When I was a student intern, as part of my credit hours I assisted special education programs at two local elementary schools and also a high school. The high school program was for severely/profoundly disabled students (students with high levels of physical and developmental disability) and was almost completely segregated from the rest of the school. Although the classroom was in the same building, students received all services outside of lunch and gym class, in that special education classroom. A "buddy" program allowed "typical" (nondisabled) students to spend their free periods as mentors and helpers in the special education room. Unfortunately, because of closeminded attitudes through the school, instead of being truly inclusive, this brought the regular students in as mini-teachers, rather than peers or friends for the disabled students.
