from the Delaware General Assembly prevented a merger between the Wilmington district and other districts as the law prevented a merger involving a school district with over 12,000 pupils. In 1969 Wilmington, du Pont, and Howard were the three comprehensive high schools in Wilmington. In response to the segregation, the 1976 U.S. District Court decision Evans v. Buchanan implemented a plan by which students in Wilmington would be bused to attend school in the suburbs for certain grades, while suburban students would be bused into the City of Wilmington for other grades. By 1981, the four current districts in northern New Castle County, Brandywine, Christina, Colonial, and Red Clay, each composed of city and suburban areas, were established, all of which were majority white at the time. The idea was that no one district would be majority poor, black, and disadvantaged. Wilmington High remained in operation under the Red Clay district until 1999 and it now houses Calloway School of the Arts. Howard High became Howard High School of Technology, and P.S. du Pont became an elementary school of the Brandywine district. University of Delaware public policy professor Leland Ware wrote that Wilmington parents were divided, with many African-Americans preferring children be educated in the city while others liked the idea of their children attending integrated schools. According to Ware suburban parents generally disliked their children being bussed into Wilmington for desegregation as suburbanites perceived Wilmington as being unsafe. In 2015 Mark Murphy, Delaware's secretary for Education, expressed support for re-establishing a comprehensive high school in Wilmington. In 2020 there were persons in Wilmington, including the mayor Mike Purzycki, advocating for this as well. Such a school would be majority African-American. Purzycki stated that fear of racial resegregation is the issue that causes community stakeholders to be reluctant to do so. Private schools There are many private elementary and secondary schools in Wilmington: Salesianum School, Serviam Girls Academy, Nativity Preparatory of Wilmington, Ursuline Academy, The Tatnall School, Tower Hill School, St. Elizabeth High School, and Padua Academy. With 17.6% of the area students enrolled in private schools, the Wilmington area ranks as one of the top ten metropolitan areas in the country for the percentages of students in private school. Wilmington Friends School is located outside of the city limits. Universities and colleges There are several colleges operating in the city of Wilmington: Delaware College of Art & Design Delaware
