Autism is a low-incidence disability that is complex to assess and for which rates continue to increase. Assessment options for autism are reviewed and presented in the context of recent research and a comprehensive, multidisciplinary assessment model. The model involves three levels that yield data progressing from more subjective and general to more objective and specific. Each level provides unique information critical to verifying eligibility, planning instruction, and monitoring progress. Because of the complexity of autism, a systematic and comprehensive assessment approach is critical to reducing error in decisions regarding eligibility and treatment.
