District 203, established in 1972 through the merger of elementary and high school districts, serves central Naperville (as well as portions of neighboring Lisle and Bolingbrook). All but two of the district's buildings are within the limits of the city of Naperville. Kennedy Junior High School is in Lisle. Steeple Run is in an unincorporated portion of Lisle Township in DuPage County. The current District 203 school buildings were constructed between 1928 (Ellsworth) and 2010 (Ann Reid Early Childhood Center). Additionally, throughout the district's history they have conducted many renovations and additions to schools. For information about renovations and additions to Naperville Central High School or Naperville North High School see their Wikipedia pages. For information on the 2010 additions, renovation, and construction of the Ann Reid E.C.C., visit Building the Future on District 203's website. Dan Bridges has served as Superintendent since the 2012-2013 school year.
