The Center for Education Reform has released their annual rating of charter school laws. Colorado earned a high B this year. No surprise that Kansas and Wyoming both earned a D.
Some of the key factors in the study are if there are multiple chartering authorities (Colorado has both local school districts and the state Charter School Institute), the number of charter schools approved (141 operate in Colorado with about 7% of the public school student population in charter schools), the automatic waiver of laws that provide autonomy (Colorado permits the automatic waiver of 13 statutes), and the automatic exemption from collective bargaining agreements (Colorado charter school employees are all at-will). Probably most important--Colorado doesn't have a cap on the number of charter schools that are permitted.
