The Reynolds Adaptable Intelligence Test (RAIT) is a rapid, reliable, and valid intelligence test designed for group or individual administration. It is composed of seven subtests that assess crystallized intelligence, fluid intelligence, and quantitative aptitude or intelligence.
Moreover, how is Rait scored?
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.
Likewise, people ask, what is total battery intelligence?
Total Battery Intelligence Index (TBII) Provides a summary estimate of general intelligence, or g, derived from the administration of all seven RAIT subtests. Total Intelligence Index (TII) Provides an alternative summary estimate of general intelligence, or g, that does not take into account quantitative intelligence.
What is the RIAS 2?
The RIAS-2 is an objective, reliable, and comprehensive test of intelligence and its major components. The new RIAS-2 Record Form with Spanish Responses is a culturally fair assessment that allows bilingual and English language learners the option of answering items in Spanish.
Does fluid or crystallized intelligence change with age?
Changes in Intelligence
Crystallized intelligence continues to grow throughout adulthood. Many aspects of fluid intelligence peak in adolescence and begin to decline progressively beginning around age 30 or 40.
