I have it from my sources that NY Education Commissioner Richard Mills could release the scores today if he wanted to; apparently, year after year, he holds onto the scores until it's a good time politically to hold a press release. My source says that he has, in the past, waited until November to release the scores.
If this is true, then NYC public school students are taking twice as many tests for nothing, as this Daily News editorial suggests.
P.S. How would Mills respond to this post? Check out this line from that interview from ETS linked above:
Objections to accountability are often hidden in objections to the tests.
