Only 12 percent of black fourth-grade boys are proficient in reading, compared with 38 percent of white boys, and only 12 percent of black eighth-grade boys are proficient in math, compared with 44 percent of white boys.
Poverty alone does not seem to explain the differences: poor white boys do just as well as African-American boys who do not live in poverty, measured by whether they qualify for subsidized school lunches.

The report shows that black boys on average fall behind from their earliest years. Black mothers have a higher
infant mortality rate and black children are twice as likely as whites to live in a home where no parent has a job. In high school, African-American boys drop out at nearly twice the rate of white boys, and their SAT scores are on average 104 points lower. In college, black men represented just 5 percent of students in 2008.
The analysis of results on the national tests found that math scores in 2009 for black boys were not much different than those for black girls in Grades 4 and 8, but black boys lagged behind Hispanics of both sexes, and they fell behind white boys by at least 30 points, a gap sometimes interpreted as three academic grades.
