Occupy Kindergarten: The Rich-Poor Divide Starts With Education
http://www.theatlantic.com/business...oor-divide-starts-with-education/252914/Economic class is increasingly becoming the great dividing line of American education.
The New York Times has published a roundup of recent research showing the growing academic achievement gap between rich and poor students. It prominently features a paper by Stanford sociologist Sean F. Reardon, which found that, since the 1960s, the difference in test scores between affluent and underprivileged students has grown 40%, and is now double gap between black and white students.
The last sentence above is inconsistent with some other evidence. Looking, for example, at the report "Historical View of Subgroup Performance Differences on the SAT" at
http://professionals.collegeboard.com/profdownload/pdf/06-1868%20RDCBR06-5_070105.pdf , the differences in academic achievement between blacks and others in Figure 2 are generally larger than the differences between low-income students and others in Figure 8.
