Aaron Pallas of Teachers College asks the question and shows that the answer is no.

Despite a decade of relentless emphasis on testing, accountability and choice, the achievement gap has barely budged.

Pallas writes:

“My conclusion? There’s been no shrinkage in the test score gap between 2006 and 2012, a period in which many of Bloomberg and Klein’s reforms have begun to reach maturity. If the only purpose of their reforms were to close the achievement gap, this flat-lining would indicate that the reforms were dead on arrival.

“That’s probably too harsh a verdict for a complex package of reforms, some of which may prove beneficial in the long run. And the point here is not a referendum on what’s happened in New York City as much as it is a demonstration that racial/ethnic group differences in test performance are stubborn, even in the face of efforts intended to minimize them.

“We are about to enter an era with a new set of Common Core curricular standards and new assessments designed to measure students’ mastery of those standards. The combination of a more challenging set of standards, a lag in the development of curriculum and the professional development that teachers need to teach to those standards, and assessments that are widely proclaimed to be more difficult than existing NCLB-style tests will likely result in plummeting rates of student proficiency in English and mathematics in the near future. Significant closure of the achievement gap may be beyond the grasp of educators who will be struggling simply to keep their heads above water in the next five years.”
