Which impacts student performance the most, gender or socioeconomic status?

Is the crisis in boys' education just a myth? A new report [2] by the American Association of University Women tries to dispel the notion that as girls continue to succeed, boys are falling behind. The report argues that the real disparity exists not between the genders but between the haves and have-nots.

In particular, African American and Hispanic students and students from low-income families are found to be less proficient in math and reading than their white and higher-income classmates, and they also score lower on standardized tests.
