[4][3] After opening its doors in 1955, the school quickly reached capacity as the small suburb experienced a major unexpected population boom during the decade.

The wrap-around architectural design, created by Perkins and Willis, preserved the athletic fields to the east of the school, saved available parking, eliminated noise from Kedzie Ave, shielded the classrooms from the afternoon sun, and created a hexagon cafeteria positioned in the center of the building with a court yard view.

Upon completion, the project unified the building and doubled the size of the school by expanding the lay out to 193,830 square feet of usable space with a capacity to serve 1,400 students.

Evergreen Park competes in the South Suburban Conference (SSC), and is a member of the Illinois High School Association (IHSA), the body which governs most athletics and competitive activities in the state.
