Congress's role in defining and promoting equality of educational opportunity has evolved over the past 55 years since "Brown v. Board of Education." Most recently, all three branches of the federal government have focused more on equality of educational opportunity for "individual" students rather than for protected classes. In this article, the authors combine two different frameworks to assess Congress's evolving role in ensuring equality of educational opportunity for all students--particularly given the new political and economic realities facing the nation. The first is federalism; the second is policy instruments for advancing varied goals in education, which the authors use to examine specific policy domains where Congress might increase its impact on equality of educational opportunity. These domains are concerned with "incentivizing equity" through competitive grants designed to reduce racial and socioeconomic inequality, improving existing categorical grant programs to make them more targeted and efficient, and strengthening enforcement of existing policies and programs. Throughout, the authors consider how recent research about equality of best be brought to bear on congressional priorities. In conclusion, they discuss the political realities facing Congress in 2012 and beyond, including partisanship and the prospect of cuts to pre-K-12 education spending.
