The University of Tennessee at Chattanooga is a public university located in Chattanooga, Tennessee. The University, often referred to as UTC or simply "Chattanooga" (especially in reference to its collegiate athletics), is one of three universities and two other affiliated institutions in the University of Tennessee System; the others being in Knoxville and Martin. UTC was founded in 1886 as then-private Chattanooga University, which was renamed in 1889 as U.S. Grant University. In 1907, the university changed its name to University of Chattanooga. In 1969, the university merged with Zion College/Chattanooga City College to form The University of Tennessee at Chattanooga as part of the University of Tennessee System. Chattanooga uses the semester system, with five optional "mini-terms" in the summer. The leadership of the campus rests upon the chancellor, who answers to the UT System President. The current chancellor is Roger Brown. A voice for student leadership on campus, the SGA consists of senators representing districts/the college they belong to, such as the College of Arts and Sciences.
