Mariemont City Schools consists of four schools, serving grades K-12 (with independent preschool programs available): Mariemont High School, Mariemont Junior High School, Mariemont Elementary School and Terrace Park Elementary School. Total enrollment is approximately 1,550 students.
- The district employs approximately 200 certified and classified staff. General administration consists of the superintendent, assistant superintendent and treasurer.
The district completed a long-term facilities plan in 2012, with extensive renovations at both elementary schools, construction of a new junior high school building in Fairfax, and renovation of part of the high school building. Mariemont Elementary, Terrace Park Elementary and Mariemont Junior High School celebrated the new buildings with dedication ceremonies on Sunday, September 9, 2012.
To follow up the 2012 facilities plan, the district began planning the Mariemont High School Facility Plan in 2016 with administration, staff, students, parents and community members, along with construction and architect experts. The project began in the spring of 2019 and concluded in the summer of 2021. It allowed the district to provide a 21st century education for its high school students with updated science labs, concentrated collaboration spaces, an improved layout for safety and security, large-group gathering areas and enhanced technology platforms, amenities it could not provide in the almost 50-year-old former building.
