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. Factor scores were derived, and these variables were clustered using the hierarchical group, The purpose of the study was to evaluate the process whereby children are identified as learning disabled (LD) and the validity of subsequent educational placements: (a) a representative sample of, This study examined the extent to which school personnel were able to differentiate learning disabled students from low achievers by examining patterns of scores on psychometric measures.

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 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. 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. We 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 full spectrum of cognitive ability. WebStructural equation modeling (SEM) and commonality analyses were applied to the Differential Ability Scales, Second Edition (DAS-II) standardization and clinical sample data. This nonverbal cognitive assessment tool is used to assess individuals from age 5 to 21 who have language or hearing impairments and also individuals who have diverse cultural and socio-economic backgrounds.
