Standardized tests show that girls — whether elementary students or college freshmen, here or around the world — know more than boys.
Girls score better in reading, writing, math and — to a lesser degree — social studies.
Boys do only marginally better in science, but as hard-wired gender roles shift and educators increasingly pitch engineering to under-represented women, girls are catching up in that last subject where boys dominate.
Women are excelling in college, too.
Between 2009 and 2013 women ages 24 and up earned four-year degrees 64 percent faster than men. More shocking is that also in that five-year window, the number of professional and graduate degree-holders grew 120 percent faster for women, according to U.S. Census Bureau data.
Despite their academic achievement, women still earn less than men regardless of college. Though the wage gap is shrinking, the longer a woman spends in college, the more likely a man with the same education level will be paid even more than her.
Several theories attempt to explain why boys and girls have markedly different educational outcomes:
• Because the academic gap exists across ages, societies and races, researchers suggest that intellectual maturity and normal child development favor females. The gap is widest at the middle-school level.
