The Woodcock-Johnson IV Tests of Cognitive Abilities (WJ IV COG) is a comprehensive assessment battery designed to assess broad and narrow cognitive abilities, as defined by the Cattell-Horn-Carroll (CHC) theory of intelligence. Previous studies examined the invariance of the WJ assessments across sex and age groups using factor analytic methods.…

Intelligence has been defined in multiple ways throughout history. In the last 100 years a psychometric approach to define the concept of intelligence has come to dominate the concept. This Commentary provides a brief overview of the history and concepts of intelligence with an emphasis on intellectual assessment. Particular focus is placed on the…

The study examined the psychometric properties of the German version of the Creative Thinking-Drawing Production Test (TCT-DP). This test evaluates creative potential with 14 content-related criteria, constituting a total score. Age norms exist for children from 4-16 years. A total of 269 children with predominantly migrant background, aged…

The Sustainable Development Goals mandate that by 2030, all children should have access to quality early child development opportunities, healthcare and pre-primary education. Yet validated measures of ECD in low and middle income countries (LMICs) are rare. To address this gap, a Systematic Review (SR) of measures available to profile the…

As a result of the upcoming Federal reauthorization of the Individuals With Disabilities Education Improvement Act (IDEA), practitioners and researchers have begun vigorously debating what constitutes evidence-based assessment for the identification of specific learning disability (SLD). This debate has resulted in strong support for a method that…

The Wechsler Intelligence Test for Children -- Fifth Edition (WISC-V) is a comprehensive intellectual ability assessment for children. The WISC-V was developed over the course of five years by an expert team including doctoral-level scientists and clinicians and an advisory panel, who provided expert advice about intellectual ability testing,…

Universal screening of very early school-age children (age 4-7 years) is important for early identification of learning problems that may require enhanced learning opportunity. In this context, use of standardized instruments is critical to obtain valid, reliable, and comparable assessment outcomes. A wide variety of standardized instruments is…

The Kaufman Assessment Battery for Children (K-ABC) attempts to improve on the theory and technology of intelligence testing. The criteria used for this evaluation of the K-ABC are adequate theoretical basis; expanded range of abilities measured; incremental as well as convergent and discriminant validity; multiple meaningful scores; and training…

The construct validity of the Sequential Processing, Simultaneous Processing and Achievement scales of the Kaufman Assessment Battery for Children was supported by factor-analytic investigations of a representative national stratified sample of 2,000 children. Correlations provided insight into the relationship of sequential/simultaneous…

Factor analyses of the Kaufman Assessment Battery for Children (K-ABC) were performed on separate groups of Anglo (n=100) and Mexican-American (n=100) fifth-grade children to determine the comparability of underlying structures and to examine the existence of possible bias in construct validity of the K-ABC for each group.
