School began classes with twenty-two pupils and two instructors. Classes were held in the lower level of the Masonic Lodge. After one unsuccessful referendum, the voters approved a proposition on October 10, 1925, to purchase a site and construct a high school. The Mt. Auburn High School was built in 1926 on what was then known as the D.C. Armstrong site, twelve lots one block east of the village park. The total cost of the original building was reportedly $44,184, with the site costing $1800. On Monday, September 6, 1926, the new Mt. Auburn High School opened for classes with 69 students enrolled. The first graduating class from the new building was in 1927. On March 1, 1949, an architect was employed to design an addition to the building which would house the library, agriculture class room and shop area. In 1951 the addition was constructed as a cost of $44,000. On November 16, 1952, this new addition was dedicated. The present elementary school was built in 1952, with a cafeteria and gymnasium, as well as a large playground and an agricultural experiment acreage. Mt. Auburn had become a unit school in 1949. On November 7, 1989, voters approved the idea to deactivate the high school and tuition the students to Taylorville High School. With the 69th graduation on May 25, 1990, the Mt. Auburn Community High School classes came to an end. Records indicate that 1135 students graduated from Mt. Auburn. In 1992 the school district annexed to the Taylorville School District. Though elementary children from grades kindergarten through fifth grade attend school in Mt. Auburn, junior- and senior-high students attend school in Taylorville. On July 4, 1992, the interior of the high school building was burned and on Monday, July 6, 1992, the building was demolished. In August 1994, a twelve-foot-square, patio-style, brick memorial was dedicated in the village park during the Mt. Auburn Farmers Picnic to honor the high school. The actual stone nameplate, salvaged from the high school, was placed on top of a black granite slab which included the etched image of the high school and its proud Eagle mascot. With agriculture and ag-related industries the biggest of the community, today approximately twenty businesses are located in Mt. Auburn, though many of these are small businesses that are run from the business owners' homes. Businesses include a gas station, greenhouse and floral shop, auto repair,
