The idea of school choice, has made substantial inroads, but Charter Schools have got a long way to go and the fight won't be easy (WSJ):
More than two decades since charter schools first appeared in the U.S. as an experiment, they are poised to become mainstream in many parts of the country. About 2.5 million, or 5.1% of public-school students, were enrolled in charter schools in the 2013-2014 school year, up from 300,000, or 0.7%, in 1999-2000, according to federal statistics.
Nearly every major city has charters, challenging the traditional public-school model as parents increasingly send their children to these privately run but publicly funded institutions and politicians allocate more tax dollars.
The dispute in Boston and similar clashes in Baltimore, Philadelphia and Los Angeles are surfacing as local charter schools reach or surpass a 15% to 20% market share in those cities.
