Hill City School District 51-2 is made up of elementary, middle, and high schools located in separate buildings on the same campus. A permanent school building was constructed in 1921 and housed all grades until an elementary school building was constructed in 1961 with several modifications in the 1980s. The Middle School was built in the 1970s with several additions in the 1990s. After the middle school was built the original school building became the high school building. In 2001, construction was begun on a new high school which was completed in 2002. The previous high school was razed in 2003. Hill City District 51-2 schools are predominantly funded through property tax on those living in the school district. The district also has adopted an open enrollment policy that makes it easier to transfer between local school districts.
