Quizplus · Accepted Answer

The most widely used IQ tests in the United States were developed by David Wechsler, including the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC). While Alfred Binet and Theodore Simon developed the first IQ test, the Binet-Simon Scale, it is not as widely used in the United States today. Likewise, Lewis Terman is known for his work on the Stanford-Binet Intelligence Scale, which is not as frequently used as the Wechsler tests.
