The RIAS-2 can be used as a stand-alone intellectual assessment or as part of a larger battery to diagnose specific disorders, such as intellectual disabilities or learning disabilities, and as a way to determine educational placement.
Fast -- Compared to similar measures, the RIAS-2 is faster as all eight subtests can be completed in less than one hour. Obtain a g score in less than 15 minutes.
Accurate -- A low emphasis on motor demand makes the RIAS-2 a more precise measure of general intelligence.
Affordable -- About half the price of similar measures.
Many intelligence tests introduce confounds in the form of construct irrelevant variance by including tasks that require fine-motor skills and that give bonus points for speed of performance on nonverbal intelligence tasks, and such speed is easily disrupted by attentional issues and ease of distractibility. Often such measures will also rely on academic tasks such as fund of information. RIAS-2 was constructed carefully to avoid as many such confounds as possible leading to a more direct measure of intelligence that is not clouded by fine motor issues, academic learning disabilities, or attentional and other noncognitive factors.

As managed care companies continue to cut and monitor hours for psychological and neuropsychological testing, time has become an increasingly valuable commodity. RIAS-2 provides a full assessment of intelligence in 30 minutes and also has conformed memory and processing speed tasks that add only 10-15 minutes. In contrast to most IQ measures, RIAS-2 saves you 45-60 minutes of testing and scoring time that can then be devoted to assessing other characteristics of your patient, allowing you to generate a more comprehensive, useful evaluation overall. Additionally, RIAS-2 record forms and protocols are less than half the cost per administration of those for competing measures and the detailed narrative report, which can be tailored to different fundamental referral questions, is also quick, easy to use, and less than half the cost of other common narrative reports. RIAS-2 thus saves on time and out of pocket expense and can improve your productivity as a clinician.

The RIAS-2 is an objective, reliable, and comprehensive test of intelligence and its major components. The 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.
Since COVID changed the way you practice, you need options to continue serving your clients seamlessly and efficiently. PAR developed the RIAS-2 Remote to support your need for flexibility. The RIAS-2 components have been minimally modified and packaged digitally, and step-by-step videoconferencing instructions are included to allow you to continue assessing your clients for intelligence and its major components in remote settings.
An equivalency study (Wright, 2018*) between the RIAS-2 paper-and-pencil format and digital version produced positive results for all subtests except the supplemental speeded processing subtests—hence, they are excluded from the Remote.
One downloadable digital stimulus book is shared via videoconferencing with your student or client.
