In the 1930s, an American professor at Stanford University, Lewis Terman, sought to revise Binet's test. Accordingly, the test is now named the Stanford -Binet Intelligence Test. The Stanford-Binet measures quantitative, verbal, abstract, and visual reasoning, as well as short-term memory (Green 263). Terman’s interest in discovering what society considers “'smart” and who was “not quite as smart”. His intentions undermine those of Binet ( Lemann 115).

Terman developed the term Intelligence Quotient, or IQ. IQ would be calculated by using the equation: mental age, divided by chronological age, multiplied by 100 equals IQ. (MA/CA x 100 =IQ) (Green 260). MA is determined what age level a student scores on. For example, if a 10-year-old score as high as a 15-year-old does on an IQ test, his or her MA would equal 15. In this case the CA is 10. Therefore this child's IQ was 15/10 x100=150 (Green and Green 261-262).
A third IQ test soon evolved in America in 1939. This test is the Wechsler Adult Intelligence Scale (WAIS-R) developed by David Wechsler. This test is said to be the most successful intelligence test for adults, even today. Wechsler's test aims to measure verbal as well as nonverbal performance, which is separate from the actual IQ score. He also attempts to measure general intelligence, which is normally referred to as the "g" factor ( Intelligence 1). Unlike the single digit number produced by the Stanford-Binet test, Wechsler's test produces two scores. Two additional forms also grew out of this test as well. One, known as he WISC-R was used for elementary school students and another for Preschool kids which is called the WPPSI. The advantage of his test is that it identified intellectual strengths in verbal and nonverbal areas (Flynn 5).
