This chapter describes contemporary approaches to the assessment of cognitive and intellectual functioning. Seven major intelligence tests are presented in terms of their origins, theoretical underpinnings, standardization features and psychometric adequacy, interpretive indices and applications, and strengths and limitations. These tests include the Cognitive Assessment System, Differential Ability Scales, Kaufman Assessment Battery for Children, Reynolds Intellectual Assessment Scales, Stanford-Binet Intelligence Scales, Wechsler intelligence scales, and the Woodcock-Johnson Tests of Cognitive Abilities. The most common diagnostic applications for intelligence testing are provided. Finally, the status of intelligence assessment as a maturing clinical science is assessed.
