History of Community High School District 155

 

A historic photo of the old Crystal Lake Central High School building.

Beginning in 1884, a single public school, Union School, taught all Crystal Lake elementary and high school students. In 1907, the high school moved into its own building on the Union School grounds. Twelve years later, Community High School District 155 was established by a ballot measure in December of 1919. H.A. Dean served as the district's first superintendent. Crystal Lake Community High School opened at the current site of Crystal Lake Central High School on May 12, 1924. The school served students from Crystal Lake, Cary, Fox River Grove, and the surrounding areas, all of whom attended Crystal Lake Community High School until 1961, when Cary-Grove High School was opened. Crystal Lake South High School opened in 1978. At that time, Crystal Lake Community High School became Crystal Lake Central. A fourth high school, Prairie Ridge, opened in 1997. The district opened an alternative education campus, Haber Oaks Campus, in 2008.
