Robert Service High School is a public high school in Anchorage, Alaska. It had an enrollment of 1,772 students as of October 1, 2014. Serving grades 9 through 12, the school was named for the poet Robert W. Service. Part of the Anchorage School District, the school opened in 1971 as the last of four high schools built by the district (and its lineal predecessor, the Anchorage Independent School District) within a decade. Service High originally operated as Service-Hanshew; as was the case throughout most of Anchorage at the time, junior and senior high schools shared a single building. As was also the case with other junior-senior high schools in Anchorage, a separate structure was built for Hanshew during the 1980s oil boom, which is located approximately two miles to the west of Service along Lake Otis Parkway. The school completed partial renovation in 2005. Its school colors are green and gold and its mascot is the cougar.
