The U.S. state of Maine has twenty-eight accredited, degree-granting institutions of higher learning. The state's land-grant university and only research university is the University of Maine in Orono. It is the flagship of the University of Maine System, which also has branch campuses in Augusta, Portland/Gorham, Farmington, Fort Kent, Machias, and Presque Isle. 
The state's three oldest institutions of higher education are Bowdoin College (founded in 1794), Colby College (1813), and Bates College (1855). The three colleges collectively form the Colby-Bates-Bowdoin Consortium and are ranked among the best colleges in the United States; often placing in the top 10 percent of all liberal arts colleges.   
The largest institution is the University of Maine, with 12,488 students, and the smallest is the Institute for Doctoral Studies in the Visual Arts, with a total of 79 students. UMaine is home to the state's only NCAA Division 1 athletic program, the Maine Black Bears. The collegiate system of Maine also includes numerous baccalaureate colleges such as the Maine Maritime Academy, Unity College, and Thomas College. There is only one medical school in the state, the University of New England's College of Osteopathic Medicine, and only one law school, the University of Maine School of Law.
