The RAIT is a rapid, reliable, and valid intelligence test designed for group or individual administration. It is composed of seven subtests that assess crystallised intelligence, fluid intelligence, and quantitative aptitude or intelligence.
Features and Benefits
- Designed to provide continuity of measurement across a wide age span.
- Can be used to help you determine a child's educational placement and diagnose various forms of childhood psychopathology; as a measure of intelligence in general clinical and neuropsychological evaluations; as part of evaluations for the diagnosis of specific disorders; in disability determinations under various state and federal programs; and as a measure of aptitude in human resources/employment settings.
- Requires minimal reading skill and almost no motor coordination and visual-motor skill, reducing the complications that may occur when manipulated objects (e.g., blocks) are used to assess intelligence.
- Administration and scoring will be available through PARiConnect; this computer version automatically calculates a measure of effort.
- Can be administered to groups or individuals and using a computer or hand scoring. This flexibility makes the RAIT a viable option for use in schools, juvenile and adult justice systems, clinical settings, and human resource and related industrial settings.
- Yields a Crystallized Intelligence Index (CII), a Fluid Intelligence Index (FII), a Quantitative Intelligence Index (QII), a Total Intelligence Index (TII), and a Total Battery Intelligence Index (TBII).
- Quantitative intelligence subtests are not included in the calculation of the TII, so you can obtain an IQ assessment that does (i.e.TBII) or does not (i.e.TII) include an appraisal of quantitative reasoning skills.
- The Score Summary Form allows you to track examinees' scores over multiple administrations and to calculate reliable change indexes.
- The RAIT was standardised on a 2010-Census-matched sample of 2,124 individuals. All formats (i.e., group and individual, booklet and computer) were found to provide common score distributions within the constraints of sampling error.
- Subtests are scaled to the T-score metric (i.e., M = 50; SD = 10); indexes are scaled to the IQ metric (i.e., M = 100; SD = 15). Other forms of derived scores, including z scores, normal curve equivalents, stanines, percentiles, and, for the younger ages, age equivalents, are provided.
- RAIT scores obtained by individuals in several clinical groups support the validation of the RAIT as a measure of intelligence. These groups included individuals with intellectual disability, TBI, stroke, dementia, learning disability, hearing impairment, and ADHD and those who were considered gifted.
- An investigation of RAIT scores' relationship to examinees' occupational industries and job complexity levels (as determined by Occupational Information Network [O*NET] Job Zone) revealed expected patterns, with median TBII scores increasing as industry moved from physically-oriented occupations to business-oriented occupations and as job complexity level increased.
- The gender bias and ethnic bias of the items were examined rigorously, using multiple methods based on item response theory as well as classical test theory.
