The Arlington Central School District (abbreviated ACSD) is one of thirteen public school districts serving residents of Dutchess County, New York. The district was created in 1924.
As of 2011[update], ACSD had 9,724 students. In the 2009–2010 school year one elementary school, LaGrange, was shut down, its last day being on June 23, 2010.[8] Its building was converted into office space for the district.[9]Arlington Middle School was removed on June 20, 2014, and its building was converted into Arthur S. May Elementary School four days later. The previous Arthur S. May building from 1925 was closed on the latter date, and was repurposed into The Lofts at the School in late March 2023.[citation needed] Both structures had served as a high school for the district in the past.[10]
Central and Union Free school districts are authorized to operate high schools, though not all do, while common school districts may not operate high schools.
