Charter schools work, in many cases. because they function outside of the fossilized, bureaucratic regulation encumbered, teacher union burdened system. No wonder they are developing a common sense of destiny and identity. Its very probably necessary for their protection and survival.
The intermingling, which began with shared “lessons learned” and expanded into shared training and more, could yield the “Internet” era of charters, a time when the real impact of the idea manifests itself, as the best schools get even better and the low-performing charters (and low-performing public schools and districts) face increasing pressure to improve or close.
