Multiple disabilities refers to a combination of conditions that significantly impact a student's ability to learn and achieve success academically. Students with multiple disabilities typically have severe physical, cognitive, and communication impairments and require extensive support across many skill areas, though their intelligence can be average or above. Their disabilities impact intellectual functioning, motor development, adaptive skills, sensory impairments, and communication skills. Effective teaching strategies for students with multiple disabilities include developing individualized education programs through a multidisciplinary process, using assistive technology, augmentative and alternative communication devices, peer tutoring, and tangible symbol systems.
