Oswego East High School, or OEHS, is a public four-year high school located in Oswego, Illinois, a southwest suburb of Chicago, Illinois, in the United States. It is part of Oswego Community Unit School District 308, which also includes Oswego High School. The high school was established in 2004 due to the growing population in Oswego, Illinois. A three-story central commons serves as the school’s social nexus and as a community event room. Adjoining the commons are a theater and performing-arts wing, a sports complex that houses two gyms, a 220-meter track, a competition pool, dance room, exercise rooms, a community meeting room with adjacent commercial kitchen, and two three-story classroom wings. From 2012 to 2013, Oswego East underwent expansions and renovations to prepare for an additional growth in student population. The additions were completed in August 2013, increasing the previous capacity of 2,400 students to 3,200 students. The original design and following additions and renovations were all completed by Kluber Architects + Engineers, earning a Crow Island School Citation from American School and University Magazine in 2005.
