Isaac was administered the Differential Ability Scales – Second Edition (DAS-II) to assess his overall thinking, reasoning, and problem-solving skills. The DAS-II provides a measure of overall cognitive abilities, as well as measure of verbal and nonverbal skills, spatial reasoning, processing speed and working memory. The DAS-II yields standard scores, which have a mean of 100 and a standard deviation of 15. Scores between 90 and 109 are considered Average for all individuals. Subtest scores are reported as T-scores. Scores between 40 and 60 fall in the average range.

He performed in the average range for Verbal Similarities (T=46) and the average range for Word Definitions (T=47). Isaac performed in the below average range for Nonverbal Reasoning (SS=87). He was asked to identify and discern patterns in pictorial and geometric shapes. These subtests provide a measure of Isaac’s ability to solve novel problems by forming and recognizing concepts and identifying and perceiving relationships. Isaac performed in the average range for Matrices (T=46) and the below average range for Sequential and Quantitative Reasoning (T=38). Isaac obtained a standard score of 105 for Spatial Reasoning, which falls in the average range. He was asked to recall and recreate geometric designs using paper and pencil and recreate patterns using blocks. These subtests provide a measure of Isaac’s ability to solve simple or complex visual problems. Isaac scored in the average range on both …show more content…

The parent ABAS 3 rating scale was sent home with Isaac to be completed by his mother. Multiple attempts and calls were given to ask Isaac’s mother to complete the rating scales however, the rating scales were not returned. This rating scale measures adaptive or functional skills, which are related to activities of daily living such as hygiene, dressing, basic consumer skills, self-direction, social and community-based skills, etc. This assessment is used to measure the personal and social skills of individuals from birth through adulthood along the developmental sequence in which individuals are expected to develop these independent living skills. Because adaptive behavior refers to an individual’s typical performance on the day-to-day activities required for personal and social sufficiency, these scales assess what a person actually does, rather than what he or she is able to do with assistance. This rating scale assesses the personal and social skills of individuals from birth through adulthood in three general domains: Conceptual, Social, and Practical skills. It also provides a composite score that summarizes the child’s performance across all 3 domains. Isaac’s scores and adaptive levels, as assessed by Isaac’s three teachers are presented in the table
