American Educational Research Association, American Psychological Association, National Council on Measurement in Education. Back in the day, (when dinosaurs roamed the earth) when other widely used tests were basing their scores on five or (for the overall composite or IQ score) 10 or more subtests, this was widely regarded as a weakness. However, the IDEA has never (ever) required high stakes decisions to be based on tests with a specific number of subtests. The test was designed to provide a unitary and valid assessment of g and components fluid and crystalized intelligence (based on Horn and Cattell model of intelligence). The RIAS presents strong evidence for reliability. Scores from the RIAS 2, of course, are not exceptions to that requirement. The facts that the test took less examiner time, meant children were out of their classrooms for a briefer time, that administering this test rather than the customary batteries resulted in amore efficient and cost effective use of the psychologists time, and that testing protocolscost less were all just icing on the cake. It correlated .88 with the Stanford Binet IV for 9 and 10 year olds. The RIAS is administered individually by experts, adjusting the difficulty by the age of the individual being examined.

To obtain clinical normative data, the RIAS was administered to 507 individuals representing 15 different clinical groups within the following categories: organic syndromes, mental retardation, learning disability, ADHD, and psychiatric disorders.
