Community High School (CHS; nicknamed "Commie High") is a public alternative school serving grades 9–12 in Ann Arbor, Michigan, USA. Located on a 3.2-acre site at 401 North Division Street near the Kerrytown district of shops, CHS today enrolls approximately 450 students.
By the early 1970s, Ann Arbor had developed a reputation as one of the most liberal campus towns in the country. The city played host to numerous radical political organizations, eventually electing three members of the left-wing Human Rights Party to its city council. Meanwhile, the teenage group Youth Liberation of Ann Arbor was carving out a role as a national pioneer in the nascent youth rights movement, with one fifteen-year-old member's insurgent school-board candidacy earning her 1,300 write-in votes, or eight percent of the total, in spring 1972. Reflecting this non-traditional ethos, the city's school district opened two experimental alternative schools during those years: Earthworks (originally Pioneer II) in fall 1971, and Community High School (CHS) in fall 1972.
Over the past decade, a number of local critics have argued that the high number of applications for CHS student slots suggested serious weaknesses at the city's traditional high schools. But, to the extent that applicants are motivated by overcrowding at the city's other schools, the problem is expected to be ameliorated once the city finishes construction on a third traditional high school, approved by Ann Arbor voters in 2004 and scheduled to open in 2008. The class of 2008 had among the top 3 highest ACT scores in the state of Michigan.
