Since 1968, A&T's academic programs were divided among nine different academic divisions.[1] 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.[9] 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.[55] All courses at the university are on a credit hour system.
