DeKalb High School dates its founding to the early 1900s as "DeKalb Township High School." The original campus was located on North First Street, now the site of Clinton Rosette Middle School. Then, constructed in 1967, a new campus building was completed on South Fourth Street and Barb Blvd., with three classroom and facility additions since then. During the 1990s and through 2008, the district experienced strong growth, resulting in severe overcrowding. On February 5, 2008, voters in the district approved a referendum to construct a new high school facility on Dresser Road; east of Annie Glidden Road. The groundbreaking ceremony was held on May 27, 2009. It opened for the 2011-2012 school year. The former campus has been repurposed for use as Huntley Middle School, the former Huntley Middle school has been repurposed as Founders Elementary School, and the former Chesebro Elementary was repurposed as an Early Childhood/Pre-K Center.
Academics
In 2014, DeKalb had an average composite ACT score of 25.3, and graduated 96.6% of its senior class. In addition, the school placed in the top 10% of schools in the nation, according to US News.
On February 7, 2009, the DHS basketball team gained national acclaim for an act of sportsmanship in a game against Milwaukee Madison High School. Just hours before the game began, Madison's senior captain Johntell Franklin learned of his mother's death. He initially informed his coach he would not play that night, but later came to the game and asked his coach to let him play. Since Franklin was not listed on the team roster, Madison would incur a technical foul, and DeKalb would get two free throws. DeKalb player Darius McNeal volunteered to take the free throws, and intentionally missed both, by rolling the ball out of bounds. Once the Madison team and fans realized that DeKalb had negated the foul to show support for Franklin, they stood and applauded. This act was reported extensively in the media, including ESPN.com, yahoo.com, World News Tonight, and the Lou Dobbs Report.
Music
In 2008 and 2012 the DHS Jazz Ensemble was named a finalist in the Essentially Ellington jazz ensemble competition, one of only 15 bands from all of North America to receive such honors.
The Dekalb High School Guys' A Cappella group, Fly Check, won the ICHSA Midwest regional championship in 2007 and 2008, and they attended nationals in New York City both years. In 2011-12, 2014–15, and 2015–16 the mixed a cappella group "Enharmonic Fusion" was selected to go to New York City for the ICHSA Finals. In 2016-17, the group placed second at the national competition.
In the 2012-2013 school year the DeKalb Marching Barbs were selected to perform, with other marching bands across the United States, at the half time show at the Sugar Bowl in New Orleans, Louisiana. During their stay in NOLA, the DHS Marching band competed against other bands in the region and won, with a clean sweep, making them able to be the band to hold the flag during the national anthem. At that time, Max McArtor appeared on television on ESPN, and Veronica Sherman was shown on the Jumbotron twice.
