			<p>WASI-II<strong>&nbsp;</strong>gives psychologists, clinicians, and researchers a fast and reliable measure of intelligence when screening for intellectual disabilities or intellectual giftedness. WASI-II&nbsp;is also useful for reassessing individuals following a comprehensive evaluation.&nbsp;</p>

			<h3>Benefits</h3>

			<ul>
				<li>Screen to determine if in-depth intellectual assessment is needed.</li>
				<li>Reassess after a comprehensive evaluation.</li>
				<li>Estimate a range of FSIQ scores on comprehensive batteries.</li>
				<li>Assesses cognitive functioning of individuals referred for psychiatric evaluations.</li>
				<li>Measure IQ scores for vocational, rehabilitation, or research purposes.</li>
				<li>Compare results to the Wechsler Family Fundamentals: Academic Skills to determine a student&rsquo;s academic strengths and needs based on an ability-achievement discrepancy analysis.</li>
			</ul>

			<h3>Features</h3>

			<p>The WASI-II builds on the strength of the WASI, providing updated versions of the WASI Vocabulary, Similarities, Block Design and Matrix Reasoning subtests. WASI-II also offers flexible administration options and strengthened connections with the WISC-IV and WAIS-IV.</p>

			<ul>
				<li>Subtests are updated to provide a variety of improvements including shortened and streamlined instructions.</li>
				<li>Four-subtest form can be administered in just 30 minutes; two-subtest form in about 15 minutes.</li>
				<li>WASI-II subtests and items are revised to more closely parallel their counterparts in the WISC-IV and WAIS-IV.</li>
				<li>Only six more subtests (rather than ten) need administering from the comprehensive measure to derive all WISC-IV or WAIS-IV composite scores.</li>
				<li>Standardization of the WASI-II was conducted from January 2010 to May 2011 on a nationally representative sample of approximately 2,300 individuals aged 6&ndash;90.</li>
			</ul>

						<ul>
							<li><strong>Updated normative sample</strong>: Norms are representative of today&rsquo;s population and extend to 90:11.</li>
							<li><strong>Simplified administration and scoring</strong>
							<ul>
								<li>Shorter discontinue rules</li>
								<li>Reversal rules are more user-friendly and more consistent with comprehensive Wechsler intelligence scales</li>
								<li>Directions organized in a more streamlined fashion and reading instructions shortened by 40%</li>
								<li>Stimulus Book enhancements improve user-friendliness:
								<ul>
									<li>Stimulus book now flips forward toward the examinee rather than backward toward you, making the pages easier to turn in situations where the testing surface is too wide.</li>
									<li>Improved coil of the Stimulus Book makes pages easier to turn and binding more durable.</li>
								</ul>
								</li>
							</ul>
							</li>
							<li><strong>Closer parallels to WISC&ndash;IV and WAIS&ndash;IV</strong>:
							<ul>
								<li>Across the four subtests, 20-40% of the WASI&ndash;II items are new or revised.</li>
								<li>Composite score names now reflect updated and consistent terminology with WISC&ndash;IV and WAIS&ndash;IV. For example:
								<ul>
									<li>VIQ (Verbal IQ) &rarr; VCI (Verbal Comprehension Index)</li>
									<li>PIQ (Performance IQ) &rarr; PRI (Perceptual Reasoning Index)</li>
								</ul>
								</li>
							</ul>
							</li>
							<li><strong>Updated versions of WASI subtests</strong>
							<ul>
								<li>Similarities subtest floor (easy items) improved with new picture item type; as well as updates to items with close attention to vocabulary level of words and content that reflects abstract concepts and reasoning.</li>
								<li>Matrix Reasoning subtest more similar to WISC&ndash;IV with realistic picture items.</li>
								<li>Block Design subtest ceiling (hard items) stronger with new and innovative items.</li>
								<li>Vocabulary subtest updated with new art as well as new ceiling items.</li>

						<p>How can I maximize my use of the WASI&ndash;II with the WISC&ndash;IV and the WAIS&ndash;IV?</p>

						<td>
						<p>Because the WASI&ndash;II is linked to both the WISC&ndash;IV and the WAIS&ndash;IV, and provides unique items and subtests that also parallel the comprehensive measures, there are opportunities to maximize the clinical utility of these tests while saving you and your clients time.</p>

						<p>The WASI&ndash;II can be used either before or after the comprehensive measures for situations in which multiple evaluations must be conducted. Because the items are unique to the WASI&ndash;II, practice effects are avoided.</p>

						<p>The WASI&ndash;II can also be used as a screening measure to determine if comprehensive intellectual assessment with WISC&ndash;IV or the WAIS&ndash;IV is necessary. WASI&ndash;II subtest scores can be substituted for the corresponding WISC&ndash;IV or WAIS&ndash;IV subtest scores because the WASI&ndash;II subtests are statistically equated to the corresponding WISC&ndash;IV and WAIS&ndash;IV subtests. More specifically, the WASI&ndash;II subtest T scores can be converted to scaled score units and used in comprehensive FSIQ derivation.</p>
