Ohio Charter Schools Go from Worse to Worser Since 2009

A new CREDO study of Ohio charters just came out.  Study available here in pdf.  Chart below is from page 18.

Here is a quote from policy analyst, Stephen Dyer, who has commentary on the CREDO study, with some good links there:

. . .at Know Your Charter, we found that less than 10% of Ohio's charter school kids are in schools that score above the state average on the Performance Index Score or have an A or B in overall value added.
