Final answer:
The continuum from least to most restrictive educational placements for students with disabilities is Inclusion, mainstreaming, self-contained classroom, followed by residential treatment.
Step-by-step explanation:
A) Mainstreaming, inclusion, self-contained classroom, residential treatment The continuum of placement options for students with disabilities from least restrictive to most restrictive is represented by the following order: Inclusion, mainstreaming, self-contained classroom, and residential treatment. Inclusion is the approach of fully integrating students with disabilities into standard classrooms, providing the same educational opportunities as their peers. Mainstreaming involves placing students with disabilities into standard classrooms for part of the day while also spending time in special education settings. A self-contained classroom is a more restrictive environment where students with more significant needs spend most or all of their day in a specialized setting. The most restrictive placement, residential treatment, provides intensive services in a residential facility rather than a standard school setting. These placements are designed to ensure that all students receive an education in the most appropriate environment for their individual needs.
Mainstreaming refers to integrating students with special needs into regular education classrooms for at least part of the day. Inclusion refers to placing students with special needs into regular education classrooms full time. A self-contained classroom is a separate classroom that is specifically designed to meet the needs of students with disabilities. Residential treatment refers to a highly restrictive placement in which students receive round-the-clock care in a residential facility.
