The four main academic sections of the building house specialized programs as part of Northwestern's initiative to provide smaller learning environments in which students can specialize in specific areas of study, similar to a college. Across the main hallway from the sub-buildings are other facilities encompassing the H, J, & K-Wings (there is no "I-Wing"), which includes the main gymnasium, auxiliary gymnasium, main cafeteria/food court (H-Wing), NJROTC unit and Child Development wing (K-Wing), and library/media center. The H, J, and K-Wings are not separate buildings like Wings A-F.
