Two commonly used and interchanged instruments are the Mullen Scales of Early Learning (MSEL), a test of developmental level, and the Differential Ability Scales, second edition (DAS-II), a more traditional cognitive test. However, curve estimation revealed large mean differences in scores that varied as a function of the child's cognitive ability level. -Marit Korkman, PhD, Ursula Kirk, PhD, and Sally Kemp, PhD. This test predicts academic achievement on the basis of ability equally well for African American, Asian American, Hispanic/Latino, and White/non-Hispanic children. The difference between overall scores is suggested to be attributable to a relative weakness in processing speed, which is assessed on the WISC-IV but not the DAS-II.

This is an updated edition of the WISC-IV and also produces standardized cognitive measures of children aged 6 to 16 years and 11 months.

WebWe evaluated the correspondence of contemporaneous MSEL and the DAS-II scores in a mixed sample of children aged 2-10 years with autism spectrum disorder (ASD), non-ASD developmental delays, and typically developing children across the Education. Psychologists use the DAS-II to learn about a childs thinking skills, memory, processing speed, spatial awareness, and verbal knowledge. PMC 0000021809 00000 n This allows for calculation of an intellectual ability without considering working memory and processing speed. The DAS-II can be scored manually or with the Scoring Assistant software included in every kit. The WISC-IV has 15 subtests with a core of 10 summarized into four composites including Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed. Participants achieved significantly higher overall scores on the DAS-II and nearly half the sample achieved a higher classification label on the DAS-II. Abstract. Farmer, C., Golden, C., & Thurm, A. Unauthorized use of these marks is strictly prohibited. Each composite index combines to form the Full Scale Intelligence Quotient which measures overall intellectual ability. Choice of assessment should be considered carefully given the systematic differences in overall scores produced in this population. Disclaimer. The limitations of standardized testing for children with developmental delay or cognitive impairment are well known: Tests do not exist that provide developmentally appropriate material along with norms that extend to the lower reaches of ability. WebThe Differential Ability Scales Second Edition (DAS-II; Elliott, 2007) is an individually administered, norm-referenced instrument that assesses the cognitive abilities of children and adolescents ages 2 years, 6 months through 17 years, 11 months. The DAS-II is useful for identifying strengths and weaknesses so appropriate individual education program (IEP) goals, intervention strategies, and progress monitoring can be developed; and comparing ability scores over time, even when normative scores cannot be obtained. Age: 2 years 6 months to 17 years 11 months, Time to Administer: Core battery: 45-60 minutes; Diagnostic subtests: 30 minutes.

Individual composite scores, including memory, analogic reasoning (thinking about similarities through comparison), spatial awareness, and numerical reasoning can also be collected and are used by psychologists to determine your childs abilities in these areas. 2. Individually administered intelligence measures are commonly used in diagnostic work, but there is a continuing need for research investigating possible test bias among these measures.
