The Middle School at Oakridge is divided into two separate divisions. The lower house (LHMS) consists of grades five and six, and grades seven and eight comprise the upper house (UHMS). Each division of the middle school has its own faculty, programs, and curriculum.

The Middle School curriculum, in both the lower and the upper houses, provides sound instruction in all academic disciplines, exploration of the fine arts, and a strong physical education and athletic program. Specifically, students in the LHMS are required to study Language Arts, Fine Arts, Math, General and Earth Science, United States and World History, Foreign Language(French or Spanish), and Physical Education. The fine arts program in the 5th grade consists of 9 weeks each of choir, art, drama and strings.
