Bienville Parish School Board (BPSB) is a school district headquartered in Arcadia, Louisiana, United States. The district serves Bienville Parish. In 2012 the superintendent replaced the principals of five of the district's eight schools after encountering poor test scores. KTBS described the move as "the largest leadership change in forty years" for the school system. The district had 2012 test scores worse than that of 2011, and was one of three parishes in northwest Louisiana to have this scenario. Around 2012 it was 50th of out all of the Louisiana parish school systems.
