The first settlers organized Symmes Township and built cabins in the township in 1820. The first settlement was at the mouth of Johns Creek, with the next being on Buffalo Creek at Yates Fork (now Caulley Creek).[6] The first school was held in the cabin of Andrew Burke on Johns Creek in 1834. There were a total of twelve students from three different townships.
The township is within Wayne National Forest. In 1989, the federal government owned 61% of the land in the township.[6]
The township is governed by a three-member board of trustees, who are elected in November of odd-numbered years to a four-year term beginning on the following January 1. Two are elected in the year after the presidential election and one is elected in the year before it. There is also an elected township fiscal officer,[7] who serves a four-year term beginning on April 1 of the year after the election, which is held in November of the year before the presidential election. Vacancies in the fiscal officership or on the board of trustees are filled by the remaining trustees.
The vast majority of K-12 educational services are provided to Symmes Township by the Symmes Valley Local School District, although parts of the township receive services from the Rock Hill Local School District, which also offers Pre-K education.
