Rapid, Reliable, and Valid Intelligence Test that can be Administered Online
The RAIT is an intelligence test designed for group or individual administration for use with examinees ages 10 to 75 years. It is composed of seven subtests that assess crystallized, fluid, and quantitative aptitude or intelligence. Give the full battery or abbreviated version.
Features and benefits
- The RAIT is a "power" test. It is timed, but not speeded.
- Can be administered by a psychologist, qualified proctor, teacher, or administrator making it a viable option for use in schools, justice systems, clinical settings, and human resource and related industrial settings.
- Composed of seven subtests that assess crystallized intelligence, fluid intelligence, and quantitative aptitude or intelligence.
- Features modern, full-color illustrations.
- Designed to provide continuity of measurement across a wide age span.
- Requires minimal reading skill and almost no motor coordination and visual-motor skill, reducing the complications that can occur when manipulated objects (e.g., blocks) are used to assess intelligence.
- Administration and scoring are also available through PARiConnect; this digital version allows you to administer the full battery (i.e., all seven subtests) or the abbreviated battery (i.e., crystallized and fluid subtests only) and automatically calculates a measure of effort.
- For non-verbal or non-English speaking clients, consider administering the RAIT-NV.

FAQs
What is the technical information for the RAIT?
Test structure
- Print and digital versions are statistically equivalent—so you can confidently assess groups or individuals using a computer or traditional paper and pencil. 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.
- Two total scores are available based on the subtests administered: The Total Battery Intelligence Index includes quantitative intelligence subtests, and the Total Intelligence Index does not.
- The Score Summary Form allows you to track examinees’ scores over multiple administrations, to calculate reliable change indexes, and to calculate discrepancy scores.
Scoring and Reporting
- Two total scores are available based on the subtests administered: The Total Battery Intelligence Index includes quantitative intelligence subtests, and the Total Intelligence Index does not.
- The Score Summary Form allows you to track examinees’ scores over multiple administrations, to calculate reliable change indexes, and to calculate discrepancy scores.
- Multiple types of scores are provided, including z scores, normal curve equivalents, stanines, percentiles, and, for the younger ages, age equivalents.
Technical information
- Standardized on a sample of 2,124 individuals matched to 2010 U.S. Census statistics.
- Print and digital versions are statistically equivalent.
- Multiple types of scores are provided, including z scores, normal curve equivalents, stanines, percentiles, and, for the younger ages, age equivalents.
- As a result of extensive expert review and statistical analysis, the RAIT’s racial, gender, and religious bias is minimal—ideal for any measure used for selection purposes.
- Validity was investigated using individuals from several clinical groups, including individuals with intellectual disability, TBI, stroke, dementia, learning disability, hearing impairment, ADHD, and those who were considered gifted.
- An investigation of RAIT scores’ relationship to examinees’ occupational industries and job complexity levels revealed expected patterns, with median Total Battery Intelligence Index scores increasing as industry moved from physically oriented occupations to business-oriented occupations and as job complexity level increased.
