In terms of student enrollment, a total of 10,071 students were enrolled (9,251 undergraduates and 820 graduates).
The Mayagüez campus is one of two land-grant universities in the tropics and the only one where Spanish is the native language (although English is also used extensively). The academic calendar has two semesters: fall (early August to mid-December) and spring (early January to mid-May). While textbooks and research materials used at the University of Puerto Rico are often in English, Spanish is the language of instruction in most courses at UPRM, and students are required to have a working knowledge of the English language. The individual professor decides the language used in class lectures and in student evaluation activities.
