The Differential Ability Scales&trade; (2nd ed., DAS&trade;&ndash;II) is unique in that it goes beyond cognitive ability testing to give insight into how a child processes information. Developed for psychologists, this child-friendly test provides information that enables you to predict their likeliness to succeed in education and to craft appropriate interventions and/or recommendations for the classroom and home. With out-of-level testing and child-appropriate start points, this time-tested assessment gives you the speed and flexibility you need for children who may struggle with longer tests.

			<h3><a id="spanish" name="spanish"></a>DAS&ndash;II Early Years Spanish Supplement</h3>

			<p>Differential Ability Scales&trade; (2nd ed.) (DAS&trade;&ndash;II) Early Years Spanish Supplement provides a more accurate picture of Spanish-speaking children&rsquo;s cognitive strengths and needs by assessing them in their primary language. Assess cognitive strengths and needs of Spanish-speaking children across a wide range of domains.</p>

			<h4>Benefits</h4>

			<ul>
				<li>Accurately identify the child&rsquo;s strengths and weaknesses</li>
				<li>Develop appropriate intervention strategies and progress monitoring</li>
				<li>Use subtests from either level of the battery, depending upon the child&rsquo;s performance on the age-appropriate subtest</li>
				<li>Supplements the DAS&ndash;II Complete Kit to provide in-depth analysis of learning abilities across a wide range of domains</li>
			</ul>

			<h4>Features</h4>

			<p>During the translation and adaptation of the DAS&ndash;II Early Years Spanish Supplement, professionals were engaged to address any cultural or language issues that might affect the assessment. The following countries, as well as specific geographic areas of the United States, were represented: Argentina, Chile, Colombia, Costa Rica, Cuba, El Salvador, Mexico, Nicaragua, Panama, Peru, Puerto Rico, Spain, and Venezuela.&nbsp;</p>

			<h4>Additional features</h4>

			<ul>
				<li>New items and four new subtests: Recall of Sequential Order, Rapid Naming, Phonological Processing, and Recall of Digits&ndash;Backward</li>
				<li>Expanded clinical samples of children with a variety of special classifications</li>
				<li>More engaging and contemporary artwork</li>
				<li>Raw scores are equated to the English raw scores for the DAS&ndash;II and then converted to a weighted ability score</li>
			</ul>

			<h3><a id="das" name="das"></a>DAS&ndash;II</h3>

			<p>The DAS&trade;&ndash;II is an individually administered clinical instrument for assessing the cognitive abilities that are important to learning. Use DAS&ndash;II to identify learning disabilities and intellectual disability and properly evaluate English learners, deaf or hard of hearing children, as well as assess giftedness.</p>

			<h4>Benefits</h4>

			<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>

			<h4>Features</h4>

			<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.</p>

			<h4>Additional features include:</h4>

			<ul>
				<li>Updated normative sample representative of the general US 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</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 disorder (ADHD); 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>
