Susan Dynarski, via a kind reader:

Public schools are increasingly filled with black and Hispanic students, but the children identified as “gifted” in those schools are overwhelmingly white and Asian.

The numbers are startling. Black third graders are half as likely as whites to be included in programs for the gifted, and the deficit is nearly as large for Hispanics, according to work by two Vanderbilt researchers, Jason Grissom and Christopher Redding.

New evidence indicates that schools have contributed to these disparities by underestimating the potential of black and Hispanic children. But that can change: When one large school district in Florida altered how it screened children, the number of black and Hispanic children identified as gifted doubled.
