Like previous versions of the Slosson Intelligence Test, the SIT-R3 provides a quick, reliable index of intellectual ability in both adults and children (ages 4 through 65). In addition, this revision is one of the few intelligence tests that can be used with visually impaired and blind individuals. New, embossed score sheets and a supplementary manual (included in the kit) make the test appropriate for use with people who have low visual acuity. Individually administered in just 10 to 20 minutes, the SIT-R3 is an excellent alternative to longer, more time-consuming intelligence tests.

    Items are drawn from six cognitive domains: Information, Comprehension, Quantitative, Similarities and Differences, Vocabulary, and Auditory Memory. Test questions use contemporary language and are free of significant demographic, racial, or sex bias. Standardized on a sample of approximately 2,000 individuals, the test now provides deviational IQs, standard scores, and percentiles.

    The SIT-R3 complements educational evaluations that target learning ability or achievement in children and adults. Widely used in schools, clinics, and industry, this popular measure continues to provide a quick, cost-effective assessment of intelligence.
