Though there has been some progress, substantial gaps remain, including opportunity, achievement, and education, he said. Black students are more likely than White students to have lower-quality teachers. In high schools with 50 percent or more Black enrollment, 25 percent of the teachers have neither a college major nor standard certification in the subject that they are teaching. In high schools with 50 percent or more White enrollment, the percentage of teachers who do not have a college major nor standard certification in the subject that they are teaching is only 8 percent.
For years Dr. Nettles has conducted research at ETS on the dangers of the achievement gap.
