Following Hurricane Katrina, the state of Louisiana took over most of the schools within the system (all schools that matched a nominal "worst-performing" metric). Many of these schools (and others) were subsequently granted operating charters giving them administrative independence from the Orleans Parish School Board, the Recovery School District and/or the Louisiana Board of Elementary and Secondary Education (BESE). At the start of the 2014 school year, all public school students in the NOPS system attended these independent public charter schools, the nation's first to do so.
