Since 1968, A&T's academic programs were divided among nine different academic divisions. During this time, the university added a number of schools including of the School of Business and Economics in 1970; School of Technology in 1987; and the Joint School of Nanoscience and Nanoengineering in 2010. This realignment would remain until 2016, when the university again realigned its academic programs in an effort to meet the objectives of their Preeminence 2020 strategic plan. All courses at the university are on a credit hour system.
