Semi privately-run charter schools currently drain $104+ million from the BPS budget. Short-term, a number of Boston-based charters seek to expand even more looking for a total of 2700 seats although only 668 seats are available under the cap, according to a report from the State House News Service. See the Mass DOE press release. This expansion would take effect in September 2016.Long-term, some proponents seek to do away with having to jump through charter cap hoops on a yearly basis, and they seek to file an initiative petition while Gov Baker eyes legislation that would do essentially the same thing.
