All‑Charter Districts Deliver Sustained Gains

After Hurricane Katrina, New Orleans converted every public school into a charter, fired the entire teaching workforce, and gave parents near‑total choice while closing or reassigning persistently weak schools. A Tulane University synthesis of a decade of studies finds the 'largest, broadest and most sustained improvement' seen in any U.S. district—across test scores, college access, parental satisfaction, and reduced youth crime involvement. — It suggests governance overhaul—choice, autonomy, and hard accountability—can dramatically outperform traditional district models, informing national debates over union power, charter caps, and crisis‑driven reform.
