"AA Piedmont District"@en . "The AA Piedmont District is a high school conference of the Virginia High School League that includes schools from Southwest and Southside Virginia, mostly in the Martinsville and the Danville areas. The schools of the Piedmont District compete in AA Region IV with the schools in the AA River Ridge District and the AA Southwest District. Until the 1990s, the AA Piedmont District was a member of AA Region III but was moved to balance the number of schools in the VHSL's AA regions."@en .
