From the Journal of Blacks in Higher Education:
In 2005, 153,132 African Americans took the SAT test. They made up 10.4 percent of all SAT test takers. But only 1,132 African-American college-bound students scored 700 or above on the math SAT and only 1,205 scored at least 700 on the verbal SAT. Nationally, more than 100,000 students of all races scored 700 or above on the math SAT and 78,025 students scored 700 or above on the verbal SAT. Thus, in this top-scoring category of all SAT test takers, blacks made up only 1.1 percent of the students scoring 700 or higher on the math test and only 1.5 percent of the students scoring 700 or higher on the verbal SAT. . . . .
If we raise the top-scoring threshold to students scoring 750 or above on both the math and verbal SAT — a level equal to the mean score of students entering the nation’s most selective colleges such as Harvard, Princeton, and CalTech — we find that in the entire country 244 blacks scored 750 or above on the math SAT and 363 black students scored 750 or above on the verbal portion of the test. Nationwide, 33,841 students scored at least 750 on the math test and 30,479 scored at least 750 on the verbal SAT. Therefore, black students made up 0.7 percent of the test takers who scored 750 or above on the math test and 1.2 percent of all test takers who scored 750 or above on the verbal section.
Once again, if we eliminate Asians and other minorities from the calculations and compare only blacks and whites, we find that 0.2 percent of all black test takers scored 750 or above on the verbal SAT compared to 2.2 percent of all white test takers. Thus, whites were 11 times as likely as blacks to score 750 or above on the verbal portion of the test. Overall, there were 49 times as many whites as blacks who scored at or above the 750 level.
On the math SAT, only 0.16 percent of all black test takers scored 750 or above compared to 1.8 percent of white test takers. Thus, whites were more than 11 times as likely as blacks to score 750 or above on the math SAT. Overall, there were more than 61 times as many whites as blacks who scored 750 or above on the math section of the SAT.
