The CREDO study found vast differences in quality. Charter students in the District of Columbia, Rhode Island, Tennessee and Louisiana posted strong gains in reading and math, far outpacing peers in local schools. But charter students in Nevada, Pennsylvania, Oregon, Texas and Arizona lost significant ground.
So... I guess no CMO's, restrictive charter laws, strict authorization, slow growth, prevailing wage requirements, participation in the state pension system and a partially unionized workforce is the way to go?
