How the College Board revolutionized the most controversial exam in America:

When the Scholastic Aptitude Test was created in 1926, it was promoted as a tool to create a classless, Jeffersonian-style meritocracy. The exam, which purported to measure innate intelligence, was originally adapted from the World War I Army I.Q. test and served as a scholarship screening device for about a dozen selective colleges throughout the 1930s. It was assumed that there was no way to effectively prep for a test geared to inborn intelligence, but as early as 1938, Stanley Kaplan began offering classes that promised higher scores. Today the company Kaplan founded and its main competitor, the Princeton Review, are joined by innumerable boutique firms (not to mention high-priced private tutors), all part of a $4.5-billion-a-year industry that caters largely to the worried wealthy in America who feel that the test can be gamed and that their children need to pay to learn the strategies.
