Charter schools are publicly funded, privately managed enterprises designed to deliver a public good. They are independently managed, but subject to a higher level of transparency and accountability than comparable municipally managed schools. That’s important because there is not just price discovery, but outcomes discovery (i.e., charters really can get superior outcomes with the same or less funding, especially in inner city settings, which no one thought was possible). Details about academic quality, progress and accountability are also revealed in the charter school system.
