In this article, Joel Klein acknowledges that scores across New York state, obviously including New York City, will be devastatingly low.

He was in charge of the New York City public schools from 2002, when he was selected by Mayor Bloomberg, until January 2011, when he was succeeded by the ill-fated publisher Cathie Black.

During his tenure, Klein boasted every year of “historic gains.”

The mayor was twice re-elected because of those alleged “historic gains.”

Klein traveled to Australia and persuaded the Minister of Education Julia Gillard that there was a New York City miracle, and she fell for it. Now Australia is copying the New York City model of test, test, test, test.

Now, Klein tells us that the students for whom he was responsible didn’t learn much at all, and that the new test scores will show just how terribly they are doing.

Australians might well ask if they can abandon the Klein plan now that its failure is evident even to Klein.

Having failed to improve achievement in New York City over his long tenure in office, he has found the answer that eluded him: the Common Core standards.

This is the miracle cure we have all been waiting for.

Is there any evidence that the Common Core standards will improve test scores?

No, the evidence is that they cause test scores to plummet, as they did in Kentucky–by 30 points–and as they have in New York.

Will they lead to higher achievement in the future? No one knows.
