After acquiring the land in 1973, a committee was established to carry out the repair works on the building which the church had bought at Tsh.55,000 and also constructed cottages for married students. After the completion of the repair work in 1974 the Seminary was moved from Ikizu to Arusha. The need to move the seminary arose from political disturbance experienced at Ikizu. Instruction began in 1975, with teachers like Dr. K. Hart, R. Lorenson and Mr. Stafford. AAS was merged with the Adventist School of Health Evangelism (ASHE), which by then situated at Heri Hospital in Kigoma School. In 1978, Tanzania Union of SDA appointed a committee chaired by Pr. E. Okeyo to prepare the process of upgrading AAS to college status. By October, a recommendation was reached and AAS became Tanzania Adventist Seminary and College (TASC) headed by Dr. Kisaka as the Principal. However, the seminary was closed down in 1995 and TASC was changed to Tanzania Adventist College (TAC).|
Further development saw the launch of affiliation with Griggs University in United States of America (USA) during which time it offered Bachelor of Arts (BA) in Theology and Religion. In 1998, the affiliation arrangement was shifted to the University of Eastern Africa, Baraton (UEAB). According to the current programme portfolio the college offers four-degree courses, two diploma courses and three certificate courses. Currently, the college is in the height of its transformation, as has been awarded a letter of Interim Authority by the Higher Education Accreditation Council (HEAC) to process its upgrading into a full fledged University, the University of Arusha.
