Mostly white schools spend $733 per pupil more than mostly non-white schools, a recent national study shows.

The study, conducted by the Center for American Progress, a left-leaning research and advocacy group, found that as the number of minority students increases at a school, the amount of per pupil funding it receives decreases.

"The United States has the most inequitable system for funding its schools of any advanced country, and as this report shows, students of color bear the brunt of that inequity," said Cynthia Brown, the center's vice president for education policy. "Our top priority must be ensuring students of color and all students receive their fair share of resources."
