Caltech has six academic divisions with strong emphasis on science and engineering, managing $332 million in 2011 in sponsored research. Its 124-acre (50 ha) primary campus is located approximately 11 mi (18 km) northeast of downtown Los Angeles. First year students are required to live on campus, and 95% of undergraduates remain in the on-campus house system. Although Caltech has a strong tradition of practical jokes and pranks,student life is governed by an honor code which allows faculty to assign take-home examinations. The Caltech Beavers compete in 13 intercollegiate sports in the NCAA Division III's Southern California Intercollegiate Athletic Conference.
Caltech is frequently cited as one of the world's best universities. Despite its small size, 33 Caltech alumni and faculty have won a total of 34 Nobel Prizes (Linus Pauling being the only individual in history to win two unshared prizes) and 71 have won the United States National Medal of Science or Technology. There are 112 faculty members who have been elected to the National Academies. In addition, numerous faculty members are associated with the Howard Hughes Medical Institute as well as NASA.
