## Education

Millersburg is within the English Valleys Community School District.
The community was previously within the Deep River–Millersburg Community School District, which was established in 1958 as a consolidation of the Millersburg and Deep River school districts. In 1992, the district closed its secondary school and began a joint whole grade-sharing program with the English Valleys district and the Montezuma Community School District, in which it sent its junior and senior high school students to both districts; each student chose which secondary school he/she wished to attend. On July 1, 2009, the DR-M district was consolidated into the English Valleys district, although a portion of it was given to the Montezuma district.
English Valleys took possession of the remaining school building in Millersburg and did not immediately decide as to its disposition. As of December 2009 it remained empty, and there were potential plans to convert the building into transitional housing for poor families or those affected by domestic violence.
