This study examined the group- and individual-level part score profiles of children with intellectual disability (ID) who participated in clinical validity studies supporting three individually administered intelligence tests. Across tests, children with ID produced group-level profiles comprising mean part scores that fell in the Low to Very Low…

Flanagan, Ortiz, and Alfonso (2007) recently developed the Culture-Language Interpretive Matrices (C-LIMs) for the cognitive assessment of children and youth from culturally and linguistically diverse backgrounds. To examine the utility of this new approach, we administered the Woodcock-Johnson Tests of Cognitive Abilities to a sample of students…

Test examiners used the Test Observation Form (McConaughy & Achenbach, 2004) to rate test session behavior of 177 6- to 11-year-old children during administration of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) and Wechsler Individual Achievement Tests-Second Edition (WIAT-II). Participants were assigned to four groups…

Many school psychologists focus their interpretation on composite scores from intelligence test batteries designed to measure the broad abilities from the Cattell-Horn-Carroll theory. The purpose of this study was to investigate the general factor loadings and specificity of the broad ability composite scores from one such intelligence test…

The recently published fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV) represents a considerable departure from previous versions of the scale. The structure of the instrument has changed, and some subtests have been added and others deleted. The technical manual for the WISC-IV provided evidence supporting this new…

Many school psychologists use the Cattell-Horn-Carroll (CHC) theory of cognitive abilities to guide their interpretation of scores from intelligence test batteries. Some may frequently assume that composite scores purported to measure the same CHC broad abilities should be relatively similar for individuals no matter what subtests or batteries…

A normative typology was developed and applied using multivariate profile analysis of subtest scores of the Universal Nonverbal Intelligence Test (UNIT) standardization sample. The results yielded a seven-profile cluster solution for the Extended Battery, and a six-profile cluster solution for the Standard Battery. Additionally, the results lend…

Investigates long-term stability of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) for children with specific learning disability (SLD), serious emotional disability (SED), and mental retardation (MR). There were no differential effects of disability groups on long-term stability coefficients. Stability coefficients for Full…

Uses confirmatory factor analysis (CFA) to address unresolved issues concerning the structure of the Cognitive Assessment System, a test of intelligence based upon the planning, attention, and simultaneous-successive (PASS) processes theory of human cognition. Results reveal that the CFA of the standardization data do not support use of the CAS…

Responds to Kranzler and Keith (this issue) by providing data from a data-driven approach that suggests the Cognitive Assessment System (CAS) has validity. Provides evidence that the interpretation of the planning, attention, simultaneous and successive (PASS Scales) theory described in the "CAS Interpretive Handbook" is well supported.…

Evaluates the criterion-related validity of unusual subtest profiles from the Differential Ability Scales. Participants were a large cohort stratified in proportion to United States Census data. Children with unusual profiles were identified and matched to controls. Two groups were compared across a variety of criteria. No group differences were…

Purpose of mini-series is to present current conceptualizations of the structure of intelligence, new research on human cognitive abilities and their interpretations, and pertinent, practical considerations regarding the use of intelligence tests in schools. Discusses educational-policy issues as well as diagnostic and treatment-utility issues.…

Addresses educational and policy issues related to use and interpretation of intelligence (IQ) tests in schools. Summarizes research on cognitive abilities and origins of individual differences in IQ. Considers implications of findings for educational and social policy. Discusses important issues related to practical application of IQ tests in…

Describes recent developments in intelligence theory, applied measurements, and research methodology that suggests new research is needed to reexamine the relative importance of both general and specific cognitive abilities in explaining school achievement. Presents summary of results that examines relationship between "g" and seven "Gf-Gc"…

Evaluates the extent to which newer IQ tests represent an improvement over their historical predecessors, the Binet and Wechsler scales, in terms of the potential for improved educational and psychological service delivery. Discusses three conceptually relevant criteria: theoretical foundations, psychometric integrity, and implications for…
