U.S. Secretary of Education, Arne Duncan, addressed Educational Equity in April 2014 stating, "Despite the educational progress we have made as a nation, large opportunity gaps remain, at a time where education is more important than ever to accelerating economic progress, increasing upward mobility, and reducing social inequality. The opportunity gaps start with our youngest learners and early childhood education as America is 25th in the world in our enrollment of 4 year olds in preschool. These opportunity gaps in early learning continue all the way through high school, as new data from our Civil Rights Data Collection show today, students of color, students with disabilities, and English language learners simply don't get the same opportunity as their white and Asian-American peers to take the math and science courses that figure so importantly in preparing for careers and college. Nationwide, black and Hispanic students are close to 40 percent of high school students, but just over a quarter of students taking AP classes, and only 20 percent of those enrolled in calculus classes. This dummying down of expectations is devastating to students, their families, their communities, and ultimately to our nation."
