Thanks so much for your comment. It is always a pleasure to engage with interested readers and fellow advocates for progressive educational reform on substantive issues.
The full report was quite long and detailed, as I’m sure you’re aware http://www.epi.org/publication/exploring-the-consequences-of-charter-school-expansion-in-u-s-cities/, and I appreciate your drawing attention to the challenges of accurately and thoroughly summarizing the findings of such a rigorous study in a mere two sentences.
Indeed, there is wide variation among localities in governance structures and in the ways relationships between districts and charters are organized. Baker found that to the extent there is central management, resources tend to be more rationally and efficiently allocated. When there are multiple parallel systems with discrete administrative structures, inefficiencies are more likely to result, though districts often find creative workarounds to maintain their operational standards despite resource constraints. From what I understand, New Orleans is a great example of a highly centralized system that is more fiscally and operationally efficient than many others.
Thanks again for your thoughts!
