All middle school drama and technical theater classes are held on the stage and include and end-of-semester presentation. 一年一度的第七届 & 8th grade Performance Workshop culminates in a weekend of public performances. Middle school students may also audition for the All-School musical and the 5th & 6th grade musical, both biennial events. Overlake offers 项目周 and summer programs designed to inspire theater students both on the stage and behind the scenes. A variety of student-run clubs are also dedicated to the performing arts.

For the majority of Overlake productions, which stem from classes, rehearsals are contained within the instructional time until the end of the rehearsal period, when longer technical and dress rehearsals are required. These after school rehearsals generally begin at 3:15 and end between 4:30pm and 6:00pm, depending on scheduling. The only production that rehearses entirely after-school (and some Saturdays) is the All-School Musical, every other year.
