ACOT will now be located at the Wyeth Mansion, behind the Metro Chamber building in St. Joseph.
ACOT was located above the Caldwell Banker building in St. Joseph, but a spokeswoman said the space was just too small.
Recently, the college added more than 1,000 students to its virtual school, and hired more employees.
Workers said they needed more space because of that growth.
"Not only is it allowing us to expand our physical location here in St. Joe, but also, it gonna allow us to do a lot more for the community. Not just out virtual online college we have now, but community events in the long run," said Nadia Thacker, Public Relations and Community Outreach Director for American College of Technology.
ACOT will be open for business, at the Wyeth Mansion, on Monday, March 10.
