Is the DAS-II outdated?
The norms for the DAS-II are now 14 or more years old, which means that there would be a substantial Flynn Effect. If you needed such measurements, the DAS-II might still be your best choice, despite the age of its norms.
Is the DAS-II an IQ test?
The DAS-II produces a General Conceptual Ability score corresponding to full scale IQ, as well as standard scores on Verbal (VIQ) and Nonverbal (NVIQ) domains.
What does the DAS 2 measure?
The DAS–II is an individually administered, clinical instrument for assessing the cognitive abilities that are important to learning. Use DAS-II to identify learning disabilities and intellectual disability and properly evaluate Spanish-speaking or deaf or hard of hearing children or giftedness.
What is the difference between WAIS IV and WISC-IV?
The WAIS-III produced a significantly higher mean Full Scale IQ score than the WISC-IV, in a sample of 16 year olds who attended special school. The difference between the mean Full Scale IQ score on the WAIS-III and the WISC-IV was 11.82 points, with the WAIS-III scoring higher.
Is there a DAS 3?
Differential Ability Scales, Second Edition (DAS-III)
What is the GCA on the DAS II?
A General Conceptual Ability (GCA) composite score is generated that reflects conceptual and reasoning abilities. Three cluster scores of the DAS-II measure more specific learning processes: verbal, nonverbal reasoning, and spatial abilities.
What is an average GCA score?
GCA score reliability ranges from an average of . 90 at the lower preschool level to . 94 at the upper preschool level, to . 95 for the school-age battery.
What is a GCA score?
The global cortical atrophy (GCA) scale, also known as the Pasquier scale, is a qualitative rating system developed to assess cerebral atrophy, especially in the context of neurodegenerative diseases.
What is the WISC IV scale used for?
The WISC-IV is a well-recognized measure of cognitive ability. The WISC-IV subscales are used to generate four composite scores: verbal comprehension, perceptual reasoning, working memory, and processing speed (see Fig. 1).
What do the scores on the WISC-V mean?
The score in each area will indicate ability in the various areas measured. For example, the score in Processing Speed on the WISC-V will indicate a person’s ability to quickly and accurately process simple visual information. The scores are obtained in a complicated and statistical way, not the percentage of questions answered correctly.
What are the Differential Ability Scales® –second edition (DAS–II)?
The Differential Ability Scales ® –Second Edition (DAS–II) continues the tradition of providing an in-depth analysis of children’s learning abilities. Using profile analysis, you can identify the child’s strengths and weaknesses so the appropriate IEP goals, intervention strategies, and progress monitoring can be developed.
How can DAS–II results be used?
Using DAS–II results in conjunction with the ERSI or PAL allows the examiner to go beyond the traditional use of ability-achievement discrepancies to determine eligibility for services, and helps school districts to more effectively respond to IDEA 2004.
