The IQ test most frequently used in the United States was devised by psychologist David Wechsler and is known as the Wechsler Adult Intelligence Scale-III, or, more commonly known as, the WAIS-III. There is also a children's version, the Wechsler Intelligence Scale for Children "III, or WISC-III. Both the WAIS-III and the WISC-III have two major parts: verbal and a performance (or nonverbal) scale. (Feldman, 231). .
