Just six new charter schools have been granted final approval by the Christie administration to open next fall, including the state’s first instance of a private school being converted to a charter.

The state Department of Education announced the six approved charters late Friday afternoon.

In doing so, the idea that the state is holding the alternative schools accountable was stressed almost as much as the notion that the state is promoting and supporting charter schools.

The new approvals bring the total to 87 charter schools operating statewide next fall.
