Lisle Community High School first opened in 1957, at the location of the current junior high. It remained there until 1974, after the elementary and high school districts merged to form Lisle Community Unit School District 202. A new building was
erected for the incoming class of 1975. In 2001, the high school received a makeover. The most notable changes were: the addition of a new auditorium, eight new classrooms, new band and choir rooms, and a second gym with a balcony. The class of 2007 was the 50th class to graduate from Lisle Senior High School, and the class of 2016 graduated with a class of about 135 students. ==Academics==
