From an editorial in the Wall Street Journal:

It’s bad enough that Democrats are killing a program that parents love and is closing the achievement gap between poor minorities and whites. But as scandalous is that the Education Department almost certainly knew the results of this evaluation for months.

Voucher recipients were tested last spring. The scores were analyzed in the late summer and early fall, and in November preliminary results were presented to a team of advisers who work with the Education Department to produce the annual evaluation. Since Education officials are intimately involved in this process, they had to know what was in this evaluation even as Democrats passed (and Mr. Obama signed) language that ends the program after next year.

… and so much for transparency …

Mr. Duncan’s office spurned our repeated calls and emails asking what and when he and his aides knew about these results. We do know the Administration prohibited anyone involved with the evaluation from discussing it publicly. You’d think we were talking about nuclear secrets, not about a taxpayer-funded pilot program. A reasonable conclusion is that Mr. Duncan’s department didn’t want proof of voucher success to interfere with Senator Dick Durbin’s campaign to kill vouchers at the behest of the teachers unions.
