Julian Vasquez Heilig of the University of Texas is beginning an investigation of the effectiveness of vouchers.

He writes here about Texas but his conclusions would apply to any other state as well.

He examines whether vouchers are cost-efficient and how they affect the public schools.

Until the past few years, vouchers were a dead issue.

Since the Republican sweep of statehouses in 2010, they are back.

This is well worth reading.
