INTELLIGENCE AND APTITUDE

CAS2: Cognitive Assessment System–Second Edition Jack A. Naglieri • J. P. Das • Sam Goldstein AGES: 5 through 18 years TESTING TIME: 40 to 60 minutes ADMINISTRATION: Individual The Cognitive Assessment System–Second Edition (CAS2) is a well-researched, norm- referenced measure of cognitive ability based on the cognitive/neuropsychological theory called PASS (Planning, Attention, Simultaneous, and Successive). The CAS2 was designed to measure cognitive processing abilities important for a broad range of differential diagnoses and instructional planning in individuals ages 5-0 through 18-11. The CAS2 provides practitioners with a valid and reliable tool to evaluate children’s strengths and weaknesses in important areas of cognitive processing. CAS2 SCORES The CAS2 Extended Battery has three subtests in each of the four PASS scales. The Core Battery includes two subtests from each of the four PASS scales. Each PASS scale as well as the CAS2 Full Scale yields a standard score with a mean of 100 and a standard deviation of 15. • Planning —a cognitive process requiring the individual to select and use a strategy to solve a problem. The subtests require the solving of novel tasks. The three Planning subtests are: Planned Codes, Planned Connections, and Planned Number Matching. • Attention —a cognitive process requiring the individual to selectively attend to a particular stimulus and inhibit attending to competing stimuli. The three Attention subtests are: Expressive Attention, Number Detection, and Receptive Attention. • Simultaneous —a cognitive process involving integrating separate stimuli into a single whole or group. The three Simultaneous subtests are: Matrices, Verbal-Spatial Relations, and Figure Memory. • Successive —a cognitive process requiring the serial ordering of things. The four Successive subtests are: Word Series, Sentence Repetition (ages 5–7) or Sentence Questions (ages 8–18), and Visual Digit Span. The CAS2 also yields six supplemental composite scores: Executive Function without Working Memory, Executive Function with Working Memory, Working Memory, Verbal Content, Nonverbal Content, and Speed/Fluency. A visual-versus-auditory comparison is also provided. TECHNICAL FEATURES The CAS2 was standardized using a group of 1,342 children and adolescents who closely represent the population of the United States. Extensive reliability and valid- ity information is reported in the Interpretive and Technical Manual that accompanies the test. The 12-subtest Core Battery Full Scale reliability is .95, with the PASS Scale reliabilities ranging from .86 to .93. Internal consistency, test–retest, and scorer reli- ability studies were conducted. Types of validity reported include content-description, criterion-prediction, and construct-identification. Validity with special populations, including persons with speech or language impairment, learning disability, gifted and talented status, attention-deficit/hyperactivity disorder, anxiety disorder, or Asperger’s syndrome, is reported. Special attention was paid to making the CAS2 fair for minority groups. Validity evidence reported in the Interpretive and Technical Manual demonstrates the test’s value for the assessment of diverse groups of children. INTERPRETATION The Interpretive and Technical Manual provides methods for interpreting scores. It explains how to examine the PASS profile, compare PASS scales, analyze subtests, and compare PASS scores to achievement. To determine intra-individual differences, the Interpretive and Technical Manual provides tables for evaluating the significance of the differences between the four PASS scale standard scores. It also provides similar tables to evaluate the significance of differences between scaled scores for each sub- test within a PASS Scale. Actuarial values are included. The CAS2 Examiner Record Form provides an Interpretive Worksheet for the calculation and recording of PASS Scale comparisons, subtest analysis, first-to-second-administration comparisons, and supplemental composite scores. Methods for using the PASS and Full Scale scores to identify cognitive strengths and weaknesses are also provided. Due to the unique information that can be obtained from the CAS2, the results may be particularly helpful when assessing special populations. The Interpretive Manual also contains additional resources for examiners, such as impli- cations for intervention based on CAS2 results, several research-based instructional pro- grams directly linked to PASS theory, and an illustrative CAS2 report presenting a written interpretation of CAS2 results.
