Time for another edition of "Phony Stats with Joel & Mike!"

From the NY Times:

Two years ago, Mayor Michael R. Bloomberg and his schools chancellor, Joel I. Klein, testified before Congress about the city’s impressive progress in closing the gulf in performance between minority and white children. The gains were historic, all but unheard of in recent decades.

“Over the past six years, we’ve done everything possible to narrow the achievement gap — and we have,” Mr. Bloomberg testified. “In some cases, we’ve reduced it by half.”

“We are closing the shameful achievement gap faster than ever,” the mayor said again in 2009, as city reading scores — now acknowledged as the height of a test score bubble — showed nearly 70 percent of children had met state standards.

When results from the 2010 tests, which state officials said presented a more accurate portrayal of students’ abilities, were released last month, they came as a blow to the legacy of the mayor and the chancellor, as passing rates dropped by more than 25 percentage points on most tests. But the most painful part might well have been the evaporation of one of their signature accomplishments: the closing of the racial achievement gap.

Among the students in the city’s third through eighth grades, 40 percent of black students and 46 percent of Hispanic students met state standards in math, compared with 75 percent of white students and 82 percent of Asian students. In English, 33 percent of black students and 34 percent of Hispanic students are now proficient, compared with 64 percent among whites and Asians.
