Established in 1962, Unicamp was designed from scratch as an integrated research center unlike other top Brazilian universities, usually created by the consolidation of previously existing schools and institutes. Its research focus reflects on almost half of its students being graduate students, the largest proportion across all large universities in Brazil, and also in the large number of graduate programs it offers: 153 compared to 70 undergraduate programs. It also offers several non-degree granting open-enrollment courses to around 8,000 students through its extension school.
