The UNIT2 is designed to provide a fair assessment of intelligence for individuals who have speech, language, or hearing impairments; have different cultural or language backgrounds; or are verbally uncommunicative. The manual describes studies of the UNIT2 being used with Black/African American, Asian American/Pacific Islander, and White examinees; Hispanic and non-Hispanic examinees; Native American and White examinees; English as a Second Language (ESL) and non-ESL examinees; and deaf
and hard-of-hearing and non-deaf/hard-of-hearing examinees. Diagnostic information is provided that is relevant to common educational exceptionalities, including intellec- tual disabilities, giftedness, and learning disabilities. The UNIT2 consists of six subtests (Symbolic Memory, Nonsymbolic Quantity, Analogic Reasoning, Spatial Memory, Numerical Series, and Cube Design) that yield scores with a mean of 10 and a standard deviation of 3. In addition, the following seven composite scores are available, each with a mean of 100 and a standard deviation of 15: Memory, Reasoning, Quantitative, Abbreviated Battery, Standard Battery With Memory, Standard Battery Without Memory, and Full Scale Battery. Normative data were collected from a comprehensive national sample of 1,802 indi- viduals in 33 states and keyed to the U.S. census estimates reported in the Statistical Abstracts of the United States 2014 . Reliability studies include internal consistency, test–retest, and scorer reliability. Coefficient alpha ranges from .88 to .96 for the subtests and .93 to .98 for the composites. Types of validity studies include content- description, criterion-prediction, and construct-identification. Criterion-prediction stud- ies indicate large to very large correlations with the CAS2, WISC-IV, SB5, CTONI-2, WJ III Cognitive, and UMAS. Validity evidence reported in the Examiner’s Manual dem- onstrates the test’s value for the assessment of diverse groups of children.
