He's the man that got you into college: Stanley Kaplan, who founded the nation's largest test prep service, died on Sunday at the age of 90. He started tutoring out of his parents' Brooklyn home in 1938, and was driven by the belief that fair testing would allow smart kids without means to rise to the top. He capitalized on the testing market just as the post-WWII GI Bill resulted in a college enrollment boom. In 2008, the company—which was sold to The Washington Post Company in 1984—posted a revenue of $2.3 billion. But Kaplan wasn't embraced in higher education circles and was criticized for helping people study for the SAT—a test people said only measured the ability to learn, rather than innate knowledge.
