Springfield High School is the town's main high school. One current student is the Squeaky-Voiced Teen. They have an air-hockey table. The building's design bears a striking resemblance to the real-life Peoria High School, in Peoria, Illinois.
As well as being a school, they have hosted events there. One such event was a ballet performance, despite the fact there was a gas leak in the school.
