The IDEA regulations put an emphasis on students being served at their home campus. Courts, hearing officers, and the Office of Civil Rights (OCR) have allowed schools to place some groups of students with disabilities on one or more campuses with non-disabled students rather than on every campus.
However, the law and regulations put a priority on the concept of students being educated with their peers and in the general education classroom to the extent possible. There also must be a “continuum of alternative placements” within the school. Also a child with a disability is not to be “removed from education in age-appropriate regular classrooms solely because of needed modifications in the general education curriculum.”
Parents should ask for the rationale for this practice and if exceptions are made and under what circumstances. Chances are the district has made exceptions for specific students. The parent could then discuss at least an exception for part of the day. Placement decisions are to be individualized and should be reviewed periodically. One size fits all models are not individualized. Circumstances/needs could have changed so that the student could be returned to the home campus at least part of the day.
