Stanford-Binet intelligence scale

n. An intelligence test originally devised by Alfred Binet to select schoolchildren who needed special attention, then modified by Lewis Terman for use in the United States and most recently revised in 2003 by Gale Roid. It is intended for use with individuals from age 3 to 89 and yields verbal, nonverbal, and full-scale deviation IQs with an average of 100 and a standard deviation of 15. It also has scores for fluid reasoning, knowledge, quantitative reasoning, visualspatial processing, and working memory, as well as the five verbal and five nonverbal subtests. It is the second-most-widely-used test of intelligence.
