[3] The district serves the Keeneyville unincorporated area and sections of Hanover Park, Bloomingdale, and Roselle.
[4] It was originally known as the Lake Street School District 20 and was established in Bloomingdale on October 4, 1887, with a one-room schoolhouse.
[3] By 1950 the district received its current name; its namesake is real estate developer Albert F. Keeney (1872-1950), who originated from Iowa and subdivided several area plots in 1932.
[3] In 1951 the district installed a gymnasium and an additional classroom at the Lake Street School, and in 1965 four extra classrooms, additional restrooms, a storage room, a boiler, and a teacher lounge were added.
Newer facilities later replaced the Lake Street School and was eventually demolished.
