The movement to split from the district eventually moved to the courts. Without even hearing the school board's argument, the judge ruled against the parents group. The issue finally came to an end when the DuPage Valley Regional Board of School Trustees voted 5–2 to reject the secession bid. In 1983, the original Wheaton-Warrenville High School became Wheaton Warrenville Middle School, reflecting a shrinking high school population and an increasing population of younger students. In 1988, with Wheaton Central aging, the board moved to renovate Wheaton Warrenville Middle School in preparation for opening it again as a high school, when Wheaton Central would need to eventually be closed. In October 1989, the school board formally proposed moving high school students from Wheaton Central back to Wheaton-Warrenville Middle School, and converting the older Wheaton Central building to a middle school. On May 9, 1990, the board officially voted to make the change, ending a situation that had again "divided residents". Even after the decision was made, there was debate over the naming of the school. In 1992, with an increase in the district's high school population, there was a need to move the high school population from the older 1925 building to the newer, larger 1973 building. The 1925 building became Hubble Middle School, and upon moving, Wheaton Central High School became Wheaton Warrenville South High School. Thus, the original Wheaton-Warrenville High School is considered the forerunner of the current Wheaton Warrenville South High School (not the same school). This can be seen in the evolution of the school seal which came from WCHS. The school colors, mascot, and nickname are continuations of Wheaton Central, while the current school's Wolverine Hall, with a green and gold color scheme, honor the earlier Wheaton-Warrenville High School from 1973–83. It is proper to write the name of the earlier school as Wheaton-Warrenville High School, with a hyphen. When the school was renamed, the hyphen was dropped to symbolize a lack of division. The hyphen in the original name implied a separation between the two communities, and also suggested that the school was not fully a part of either community, and instead existed as a separate entity between them. By removing the hyphen, the school is effectively signaling that it is no longer separating the two communities, and instead is fully a part of both. The new name, Wheaton Warrenville South High School, does not
