It's entirely appropriate that the Louisiana Senate would require schools participating in a possible New Orleans voucher program to "administer state tests to voucher students." That's hardly out of line for other voucher programs. Milwaukee's requires schools to test all students (not just those in the program); D.C.'s requires all voucher recipients to participate in an annual evaluation--i.e., testing. (Though, regrettably, the D.C. results aren't broken out by school.)
These are public dollars. The more transparency, the better.
