Troupe #355 is one of the few continually operational high school thespian troupes chartered by the National Educational Theatre Association. The Troupe is nearly 50 years old, and performing is only a small part of its work. In Troupe #355, students are encouraged to be very hands-on and learn how to do work behind the scenes as well as on stage. They manage all aspects of each production including directing; scenery; costumes; make-up; publicity; programs; lighting; sound; concessions; ticket sales; props; and various other jobs. The Troupe produces and assists a total of twelve productions each school year, all being student-led.
By national rules, members are formally inducted into the Troupe after earning 10 points, with partial or full points awarded for hours spent across various off and on-stage responsibilities. Each point represents 10 hours of work. New members of troupe #355 are inducted every year during the last show, the Spring Festival of Plays. Higher levels of membership come with additional tallies of hours dedicated to the Troupe.
