[2][3] The campus is located less than 10 miles north of Peoria, Illinois, and serves a mixed city, village, and rural residential community.

A variety of varsity sports are offered, including dance, cheer, baseball, softball, basketball, volleyball, football, soccer, cross country, track and field, tennis, golf, swimming and diving, and lacrosse.

[17] The scholastic bowl team has been successful, qualifying for five IHSA state tournaments, placing fourth in 2017, and winning six regional titles in seven years from 2012 to 2018.

Monthly membership dues of 5 cents helped fund basketball, tennis, and track teams at the high school.

A new high school was built in 1976, with large spaces for home economics, industrial arts, a computer lab, a business department, chemistry and biology labs, music rooms, foreign language and English classes, mathematics, and fine arts.

Along with the new school came updated athletic facilities, including a football stadium, an all-weather track, and a heated indoor pool.

In 2000, most of the old high school was demolished, with the remaining classrooms and gym becoming "Dunlap District #323 Activity Center."

In 2011, the athletics facilities at the school were renovated at a cost of $5,000,000, including an artificial turf football field, new soccer and tennis complexes, and added concession stands.
