The area of Vauxhall was primarily black and Jefferson Elementary School was disproportionately black compared to the rest of the town. Union avoided problems by converting Jefferson Elementary into a sixth-grade only school called Central 6 and bused all children in the district in 6th grade to Jefferson Elementary School. It was later renamed Central 5 housing all fifth-grade students because the two junior highs, Burnet and Kawameeh, became middle schools and took on sixth grade students.
