This article provides a 24-year update on the 10 standardized tests used most frequently with children and youth by school psychologists. Data were acquired from 64 countries through an international survey, with one respondent from each country. The informants were solicited due to their expertise in the area of assessment. The data from the current 2013 survey are described and discussed as well as contrasted with the 1989 survey data. The 2013 survey data led to the following rank order of tests based on data from the 64 countries: the Wechsler Intelligence Scales for Children, Ravens Progressive Matrices, Wechsler Preschool and Primary Scales of Intelligence, Child Behavior Checklist, Bender-Gestalt Test, Child and Adult Apperception Tests, Kaufman Assessment Battery for Children, Draw-a-Person Test, Stanford-Binet Intelligence Scales, and the Wechsler Adult Intelligence Scales. Survey data from advanced, developing, and emerging counties also are compared and discussed. Results are discussed in the broader context of international test development and use.
