| Sub-Tests |

| "DAS comprises 17 cognitive and 3 achievement subtests. In addition to obtaining a General Conceptual Ability score for a child, you can obtain cluster scores, including Verbal and Nonverbal Ability for the Preschool subtests, and Verbal, Nonverbal Reasoning, and Spatial Ability for the School-Age subtests. For language impaired and non-English speaking children, a Special Nonverbal Composite may be obtained. You can also assess distinct, interpretable abilities with subtests and items appropriate for a child’s age and ability level. Harder or easier sets of items can be administered to children expected to be of unusually high or low ability." |

| Scoring |
|
|
| |
| "The General Conceptual Ability score (mean of 100, standard deviation of 15) is an excellent predictor of academic achievement. Highly reliable (low- to mid-.90s), it is a measure of the child’s conceptual and reasoning abilities. " "Scores on the three achievement subtests can be reported as Grade Equivalents and Grade Percentiles, as well as age-based Standard Scores (mean of 100, standard deviation of 15)." |
