			<p>The DAS&ndash;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.</p>

			<h3>Benefits</h3>

			<ul>
				<li>Identify a child&rsquo;s strengths and weaknesses so the appropriate IEP goals, intervention strategies, and progress monitoring can be developed.</li>
				<li>Predict achievement on the basis of ability equally well for African American, Asian, Hispanic, and White/Non-Hispanic children.</li>
				<li>Compare performance on the subtests, tapping similar constructs from each battery to test hypotheses about the reasons for high or low scores.&nbsp;</li>
				<li>Compare ability scores over time, even when normative scores cannot be obtained for a child of a given age.</li>
				<li>Can be used with Children&rsquo;s Memory Scale or NEPSY to incorporate information on memory function.</li>
			</ul>

			<h3>Features</h3>

			<p>The DAS&ndash;II is built upon the strong cognitive foundations of the original DAS. It has 20 cognitive subtests, including 17 subtests from the original DAS. Two of the original DAS subtests, Block Building and Pattern Construction, have been combined and four new subtests added.</p>

			<p>The subtests are organized in two batteries based on age: Early Years and School-Age. The subtests in each battery are subdivided into core and diagnostic subtests. Additional new features include:</p>

			<ul>
				<li>Updated normative sample representative of the general U.S. population. The Early Years and School-Age batteries were normed for overlapping age ranges, and both were standardized with children ages 5:0&ndash;8:11.</li>
				<li>Four new subtests: Recall of Sequential Order, Rapid Naming, Phonological Processing and Recall of Digits&ndash;Backward.</li>
				<li>Subtests map onto neuropsychological constructs, and reflect recent research in working memory and reading acquisition.&nbsp;</li>
				<li>Clinical samples expanded to include children with a variety of special classifications: developmental risk; reading, writing, and math learning disabilities; attention-deficit/hyperactivity disorders; specific language impairment; limited English proficiency; mild to moderate intellectual disability; and gifted and talented.</li>
				<li>Modified administration and scoring procedures to enhance the user-friendliness.</li>
				<li>Spanish language translation of directions for nonverbal subtests.</li>
				<li>CD with examiner instructions to assist with administration of the phonological processing subtest, and signed nonverbal subtest administration directions (signed sentences).</li>
			</ul>
