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 intellectual 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, Full-Scale Battery.
