You should really read Auditor Bump's report on charter schools

You can find the press release here, and it's hard to find just one section to quote from:

An audit survey of charter schools and their related traditional school districts illustrated a lack of clarity, little sharing of best practices, and in several cases, a difficult working relationship between charter schools and traditional school districts. In addition, the audit reported that of the 48 charter school renewals during the audit period, none were subject to adverse action for the lack of sharing of innovative programs and best practices.

It was unclear why certain deficiencies in one charter school might mean a school’s charter being conditionally renewed while similar deficiencies at another school did not result in conditions being applied to its renewal.
