Colorado State University (CSU) got its start as an agricultural college in 1870, six years before Colorado was even a state. The school still has agricultural and forestry programs, as well as a veterinary medicine school, but it also offers degrees in liberal arts, business, engineering, and the sciences. True to its roots as a land-grant college, CSU engages the larger community in research and outreach through statewide Cooperative Extension programs and centers like the Colorado Agricultural Experiment Station. More than 30,000 students are enrolled at CSU, about 80% of whom are Colorado residents. It employs about 1,500 faculty members and has a student-to-teacher ratio of 19:1.
