"Researchers found that teachers and parents were less likely to refer high-ability blacks and Hispanics, as well as children learning English as a second language, for I.Q. testing. Multiple factors could be at work here: Teachers may have lower expectations for these children, and their parents may be unfamiliar with the process and the programs. Whatever the reason, the evidence indicates that relying on teachers and parents increases racial and ethnic disparities."
