Lewis Terman, a professor from Stanford University, revised the test, extended the upper ends of the test range from teenagers to superior adults. This revised test is known as the Stanford-Binet intelligence test.
Later William Stern would add further to this, creating what is known as an intelligence quotient, or IQ. Which is found by diving a person's mental age by their chronological age, then multiplying that number by 100. This test would be used later in World War I by the United States, administering it to troops in order to determine who would be trained as officers and who would be trained as enlisted men.
