Education
Fredericksburg is part of the Southeast Local School District, which includes the villages of Apple Creek and Mount Eaton in Wayne County, and the village of Holmesville in Holmes County. Fredericksburg students attend Fredericksburg Elementary from K to 6, and join their counterparts from the aforementioned villages at John R. Lea Middle School for grades 7 to 8, and finish up their curriculum at Waynedale High School for grades 9 to 12. The current schoolhouse was built in 1891 at a cost of $20,000, and served as the primary high school for the Salt Creek Local School District until the consolidation with Paint Local, and East Union Local School Districts in Wayne County, and Prairie Local School District in Holmes County combined to form the present day Southeast Local School District in 1955 upon completion of Waynedale High School. Fredericksburg High athletic teams were known as the "Freddies," and won multiple championships in basketball and baseball in the now defunct Wayne County "B" League, despite being one of the smallest school's competing. The current building has been added onto multiple times: In 1923 a gym, auditorium and classroom space were added, in 1941 a Farm Shop was added to the west side of the building, in 1967 two rooms were added, and in 1989 with the addition of three more classrooms and two restrooms.
