Students with severe disabilities will require adaptations beyond those described in the Adaptive Dimension. These students may require modification of both goals and content of materials presented. Those with certain physical disabilities will also require specialized vehicle equipment. Personal program plans should be in place for students with severe disabilities. Instructors should work together with special education staff locally and, as required, regionally or provincially to develop inclusionary plans for students with disabilities. Agencies which provide equipment and programs for persons with physical disabilities should be involved where specialized equipment is required. Agency representatives, special education personnel, parents or caregivers and the students themselves can assist instructors to develop and to deliver appropriate programs.
