An Evidence-based Comparison of Cognitive Ability and Intelligence Tests in Identification of Gifted Learners
February 21, 2013

John D. Wasserman, Ph.D.
This program provides an independent, objective, and evidence-based comparison of nine major multidimensional ability/intelligence tests in terms of their applications and use with gifted learners. Among the test comparative features to be discussed are psychometric adequacy (reliability, validity, and fairness) and demonstrated capacity to identify gifted and talented students. The individually-administered tests include the Cognitive Assessment System (CAS; Naglieri & Das, 1997), Differential Ability Scales (DAS-II; Elliott, 2007), Kaufman Assessment Battery for Children (KABC-II; Kaufman & Kaufman, 2004), Reynolds Intellectual Assessment Scales (RIAS; Reynolds & Kamphaus, 2003), Stanford-Binet Intelligence Scales (SB5; Roid, 2003), Wechsler Intelligence Scale for Children (WISC-IV; Wechsler, 2003), and the Woodcock-Johnson Tests of Cognitive Abilities (WJ III NU Cog; Woodcock, McGrew, & Mather, 2001, 2007). The group-administered tests include the Cognitive Abilities Test (CogAT Form 7; Lohman, 2012) and the Otis-Lennon School Ability Test (OLSAT 8; Otis and Lennon, 2003). The learning objectives of this program are:  1) To become familiar with the comparative strengths and limitations of individual and group cognitive ability tests with respect to identifying gifted learners; 2) To conceptualize the importance of fitting individual test characteristics with the special characteristics of the gifted sample to be tested; and 3) To understand objective psychometric criteria by which tests may be compared for any application, including identification of gifted learners.
