Trends in the assessment of infants and toddlers with disabilities

Public Law 99-457 requires a multidisciplinary assessment and evaluation of children with disabilities in five domains: cognitive development, physical development, language and speech development, psychological development, and self-help skills; and this assessment must include information required in the Individualized Family Service Plan. A variety of assessment instruments are available, and some of the most notable are surveyed in this article. Traditional tests, as well as more current, naturalistic assessments, are reviewed. The author cautions against using one test for all purposes, or using a test that has an insufficient research base.
