Quantifying the Gap

The debate over America's "education gap" -- the divide that separates wealthier, predominantly white students from those who are poorer and of color -- is being waged at local school board meetings, in the halls of congress and in your local newspaper.

The debate over America's "education gap" -- the divide that separates wealthier, predominantly white students from those who are poorer and of color -- is being waged at local school board meetings, in the halls of congress and in your local newspaper.

On March 6th, in the second of the Tisch three-lecture series, Teachers College researcher Richard Rothstein estimated the gap in percentile points, presenting new data showing black youth trailing on eight broad outcomes measures. By assigning percentile rankings on a national distribution to "the average white student" and "the average black student," Rothstein is able to show that the overall "educational equity gap" between black and white 17-year olds stands at just under 20 percentile points.
