The Stanford-Binet documents the cognitive strengths and weaknesses of children, adolescents, and adults. Its 10 subtests assess five cognitive factors: Fluid Reasoning; Knowledge; Quantitative; Visual–Spatial; and Working Memory.
The SB-5 remains among the most widely used intelligence tests because it is effective with so many different groups. Its numerous high-end items make it an excellent measure of giftedness. At the same time, improved low-end items make it appropriate for lower functioning individuals. In addition, child-friendly manipulatives make the SB-5 a popular choice for preschool testing, while the inclusion of memory items supports its use with older people. All SB-5 items have proven unbiased in regard to gender, ethnicity, culture, religion, region, and socioeconomic status.
