Possessing a genius intellect and an eidetic memory, Howser participates in a longitudinal study of child prodigies until his 18th birthday. He earned a perfect score on the SAT at the age of six, completed high school in nine weeks, graduated from Princeton University in 1983 at age 10, and finished medical school four years later. At age 14, Howser was the youngest licensed doctor in the country. As a newspaper article (one of several noting some of Doogie's aforementioned accomplishments that are shown in the series' opening title sequence) stated, he "can't buy beer... can prescribe drugs".
