St. George High School was established in 1894 in the sail loft over Long's Store. Its building was erected in 1900, graduating its first class in 1901. It, too, closed as a result of population decline, graduating its last class in 1962. For the 1962–1963 academic year, high school students attended Georges Valley High School in Thomaston. The old building was used as the new elementary school, before being demolished a few years later and replaced by the current town office and fire station.
