The Calhan School District RJ-1 is a public school district serving northeastern El Paso County, Colorado as well as parts of southern Elbert County. Serving a relatively small population, the entire educational range of the district, from preschool through twelfth grade, is housed on a single campus, along with all of the administrative functions.
The school (and district) mascot is the bulldog.
The Calhan School District RJ-1 divides its grades into three schools, but they are all hosted on the same campus.
