In 2009, Stanford's CREDO report showed that Ohio's Charter Schools were not doing well, but did do well on some measures. Four years later, they're doing worse. Ohio is one of only 4 states to have seen their schools do worse now than four years ago.
According to the report, Ohio Charter School students lose the equivalent of 14 days of learning in Reading and 43 days of learning in Math. That's 3 weeks in Reading and nearly a full marking period of Math.
That's much worse than we could have imagined. It is time to have a serious discussion about Charter School quality in this state.
