Walton High School is a Cobb County School District high school for ninth through 12th grade on Bill Murdock Road, the same road as Dodgen Middle School. It is the only East Cobb school on the district’s charter school directory: a conversion charter since July 1, 1998, according to its charter renewal (PDF), with goals set through June 2028 and a school-level board, the Walton Governance Board. Admission works like any zoned school: the renewal says Walton “is a neighborhood school that serves the local attendance zone created by the Cobb County School District” and “does not participate in a lottery system.” The school’s site calls it “a public, four-year, comprehensive high school with a strong college-preparatory program.” Its mailing address says Marietta, but the address sits outside any city’s limits, in unincorporated Cobb County, according to the Census Bureau’s geocoder.
