In this national examination of charter authorizing, researchers explore how well existing state policy environments are supporting effective schools and authorizers. Data collected from nearly 900 individuals across 23 states and the District of Columbia reveals important findings across states, including: most major authorizers are doing an adequate job, but red tape and "compliance creep" are concerns; many state policy environments are not supportive of chartered schools and authorizers; local school boards generally do not make good authorizers; states with fewer authorizers, serving more schools each, appear to be doing a better job; and, quality authorizing costs money.
