In August 1970, the Dearborn campus received its first accreditation independent from the Ann Arbor campus, from the North Central Association of Colleges and Schools.[17] In April 1971, it was officially renamed the University of Michigan–Dearborn (UM–Dearborn).[15] In July of that year, Leonard E. Goodall, the vice-chancellor of the University of Illinois at Chicago Circle, was appointed UM–Dearborn's first chancellor.[17] In the fall of 1971, the university officially became a four-year institution as it welcomed its first freshman class.[18] There were 313 freshmen in that first class and overall enrollment grew by 50% to 1,369.[19] University enrollment grew rapidly during the course of the decade, exceeding 6,000 in 1979.[20] UM–Dearborn announced both a $19 million campus development plan and the creation of its Alumni Society in November 1973.[21][22]
