Reynolds Intellectual Assessment Scales™

The RIAS-2 Normative Update (NU) measures general intelligence, verbal and nonverbal reasoning, memory, and processing speed without sacrificing clarity. In the 20+ years since its original publication, the RIAS has become known for offering a modern, efficient alternative to traditional intelligence tests. It has significantly enhanced the accessibility and accuracy of cognitive assessment in clinical and educational settings across the United States.

The RIAS-2 NU produces an objective, reliable assessment of general intelligence and its two primary components, fluid and crystallized intelligence as well as verbal and nonverbal memory, and processing speed.
