The school is built upon the former Linby Naval Outlying Landing Field (OLF # 07815 / Auxiliary Field #6 (Ottumwa)), built in 1943 for training purposes. This airfield was one of 15 satellite airfields used during WW2 by Naval Air Station Ottumwa, which conducted primary flight training from 1942-47. There are four concrete runways in a diamond shape, each about 200' wide by 2000' long. Prevailing winds made take-off and landing difficult so it was little used. It was closed at some point between 1948-55. Sale of the airport to the regional school system was contingent on the runways being retained in case the government ever needed them again. The high school was built on one of the runways and the first classes were in 1961. Today, some of the runways are used for school parking and maintenance equipment, and is also used for training practice for surrounding police departments.
The school teaches math, science, English, and other subjects common in public schools. For eighteen years, only the high school students went to the regional school, which is located a mile south of Pekin, but in 1978, all grades, K-12, began to study at the regional school, with local buildings being permanently closed.
