3 in our highschool, An auditorium with, I'm assuming, around 500 seats, A classroom with electrics and power rails run and a 2" raised stage with proper curtains, seats about 50 people. And an outdoor Ampitheater which is in a pretty bad spot and is almost never used, the only access to it is either through the Back door of the Auditorium dressing room , or through the Pottery/art classrooms, needless to say, it's used more as a large wall painting canvas than an actual theater.
My school district had a 1000 seat prosceniumtheatre, a little black-box "multipurpose room" in the highschool and a 650 seat thrust at the middle school. Elementary schools of course had their gyms with assorted stages and electrics in disrepair but I never had to deal with those much.
Where I work now all the world is a stage, since we work in hundreds of venues in the area.
Two theatres
main stage 50' proscenium, 470/718 seats
drama "pod" 20' proscenium, 124 seats
choir "pod" lecture hall 124 seats
The two pods (turntables) rotate into the main house to make 718 fixed seats
we also have two large "handicap" seating areas that have flexible seating to bring us up to 750, all told.
Main stageproscenium with a black box/studio in the same building.
Secondary auditorium across campus. Recently built but no fly space, small back stage and limited amenities.
Large assembly hall/auditorium in central campus. Used for movies and other concerts, but never live theatre, as the space is a barn. Long, poorly lit, no back stage, no flys, little amenities.
Small, intimate prosceniumin one of the residence halls. Used for student shows, projects and class presentations.
one 881 seat Auditorium shared by Drama, Music, Dance, Speech and pretty much everyone else in the school.
We have been lied to 3 times about getting a black box
933-seat 50' proscenium. No flies (all dead hung battens and raceways). We usually perform our Fall Play with the audience "on stage" with seating for about 140.
We have a 590 seat proscenium space, and a 188 seat black box in our drama building. Around grounds, we also have a 800 (or so) seat thruststage, but it's used mainly for music department events. We also have the 14k seat arena, an outdoor amphitheatre, and various lecture halls at our disposal, but we would never do department shows in them.
Two primary performance venues and then some other stuff
Main stage is 800ish auditorium for concerts, dance, chapel, large lectures
smaller theater is 350 seat primarily for drama
Coffee house sort of venue seats however many people show up that night. Singer/songwriter stuff and student activity stuff
Large ballroom gets used for performance space occasionally seating depends on set up
Does the TV studio count?
1-auditorium, large open room used for anything from sit down dinners to fashion shows and dances-has stage lighting, sound, projectorscreen
1-smaller room used for the same types of events but smaller scale-has sound system and projectorscreen
4-meeting rooms used for small events and organization meetings-each has a sound system and projectorscreen
The University itself has a theatre in the oldest building on campus which is used for some formal events and concerts.
The performing arts center has one main theatre and two smaller ones. None of these three is a prosceniumstage, it makes for some interesting set construction.
