But the rate has improved by three percentage points over the past two years. More encouraging is the fact that over the past seven years the black student graduation rate has improved at almost all of the nation's highest-ranked universities. On page 11 of this issue of JBHE we report the encouraging news that African-American enrollments at the vast majority of our nation's highest-ranked colleges and universities have shown significant improvement over the past quarter-century. But a more important statistical measure of the performance of blacks in higher education is how many black students throughout the nation are completing school and earning a college degree. Department of Education data reveals that, as expected, black students who earn a four-year college degree have incomes that are substantially higher than blacks who have only some college experience but have not earned a degree. Most important, blacks who complete a four-year college education have a median income that is near parity with similarly educated whites.
