The UNIT is designed for use with children and adolescents from ages 5.0-17.11 years, and is intended to provide a fair assessment of intelligence for individuals who have speech, language, or hearing impairments; different cultural or language backgrounds; or those who are verbally uncommunicative. The Manual describes studies of the UNIT being used with African Americans, Asians, Hispanics, Native Americans, and individuals with limited English proficiency or those who are deaf/hearing impaired. Diagnostic information is provided relevant to common educational exceptionalities, including mental retardation, giftedness, and learning disabilities.
Nonverbal Administration
Unlike many nonverbal tests which include just matrices, the UNIT subtests require multiple response modes, including use of manipulatives, paper-and-pencil, and pointing. The subtests were developed to engage and interest children across races, ethnicitys, and cultures.
The examiner uses eight relatively universal hand and body gestures to explain tasks to the examinee. In addition to these gestures, UNIT administration employs examiner demonstrations, sample items, corrective responses, transitional checkpoint items, and scored items that do not permit examiner feedback.
Subtests and Quotient scores
Each of the six subtests will yield scores with a mean of 10 and a standard deviation of 3. In addition, the following five quotient scores are available, each with a mean of 100 and a standard deviation of 15: Full Scale Intelligence Quotient (FSIQ); Memory Quotient (MQ); Reasoning Quotient (RQ); Symbolic Quotient (SQ); and Nonsymbolic Quotient (NSQ).
Standardized through a carefully designed stratified random sampling plan, the UNIT resulted in a sample that closely matches the population according to 1995 U.S. Census data. Normative data were collected from a comprehensive national sample of 2,100 children and adolescents, ages 5.0-17.11 years. Data were collected in 108 sites across 38 states. When individuals from reliability, validity, and fairness studies are included in the standardization sample, a total of 3,865 children and adolescents were examined.
Reliabilities are high, and validity studies include exploratory and confirmatory factor analyses, which provide consistent support for the structure of the UNIT. Validity studies show strong concurrent validity with many other measures of intelligence, and the UNIT appears to be a good predictor of academic achievement. In addition, discriminant validity evidence is reported, demonstrating that the UNIT differentiates among individuals with mental retardation, learning disabilities, speech/language impairments, or those who are gifted.
