History of Psychological Testing
Serious research efforts on the use and usefulness of tests began during the 20th century
The first test of mental ability, the Binet–Simon Scale, was published in 1905, followed by the Stanford–Binet in 1916 and the Wechsler–Bellevue Intelligence Scale during the 1930s
The first personality test, the Personal Data Sheet, was published during the 1930s, followed by the Woodworth Psychoneurotic Inventory, the Rorschach Inkblot Test, and the Thematic Apperception Test
The first vocational tests were published during the 1940s, beginning with the General Aptitude Test Battery
Today, psychological tests are a part of the American culture, and there are tens of thousands of psychological tests available
