A new report by the Sutton Trust has added to concerns about inequities in Britain's elite universities, Times Higher Education reported. In the period of 2007-9, five schools accounted for 5 percent of all students admitted to the Universities of Cambridge and Oxford. That's the same share of the Cambridge and Oxford populations produced -- in total -- by 2,000 other high schools. The report notes that students at some high schools do much better on tests than do students at other high schools. But the analysis suggests that more than test scores are at play. For instance, the research found two schools with nearly identical scores by students on the national tests of academic performance. One school sent 65 percent of students to Britain's 30 top universities, while the other sent 28 percent.
