Education The Town of Newburgh is served by the Warrick County School Corporation, and there are four elementary schools, two middle schools, and Castle High School. The four elementary schools are Castle, Newburgh, Sharon, and Yankeetown. The two middle schools are Castle North and Castle South. The Indiana Board of Education awarded all of Newburgh's public schools an "A" grade, the highest possible. Additional private schools are located in surrounding communities. Newburgh is served by two branches of the Ohio Township Public Library System. The branch was established on May 15, 1916, in downtown Newburgh as a Carnegie endowed library. The Downtown Newburgh branch underwent a renovation that was completed in 1984. The Bell Road library became the main branch in 2005. In 2017, the library joined the Evergreen Indiana consortium, which allows patrons to borrow materials from over 100 libraries across Indiana.
