In November, Massachusetts voters will decide whether the Department of Elementary & Secondary Education (DESE) can raise the cap on the number of charter schools allowed, or increase enrollment in existing charters in underperforming districts. If the referendum is approved, the city of Boston—which currently has 27 Commonwealth charter schools that operate independently of the district and educate about 14 percent of the student population—will likely see an increase in charters over the next several years. It’s an advance that charter advocates firmly champion but opponents see as another little push in the direction of a very steep cliff.
