Millersburg, just like New Paris Elementary, used to be a K-12 school until Fairfield Junior-Senior High School opened up in 1968. Millersburg is a predominately Amishelementary school. In 1999, a new elementary school was created, it was called, Benton Elementary School, and it would serve rural areas throughout New Paris and Millersburg. In 2008, Fairfield Community Schools had a board meeting upon the issue of the decreasing number of students at Millersburg Elementary, and the rapid growth of Benton Elementary. Fairfield Community Schools ruled that Millersburg would serve a wider area of land to raise the number of students, and keep Benton from overflowing. This eventually fell through and Millersburg got no new students from Benton.
