More minority and low-income students are enrolling and graduating from college, according to a new report from the Education Trust. The report, “Replenishing Opportunity in America,” tracked the progress of more than 3.5 million students at two- and four-year colleges in 22 systems. From 2005 to 2009 the systems enrolled 23 percent more minority students and 42 percent more low-income students. The number of those students graduating from college also grew, with 18 percent more minority and 22 percent more low-income students earning degrees. But the report also says that two-year colleges continue to struggle to graduate students, with less than one-third of first-year students completing either a certificate or an associate degree, or transferring to a four-year institution. The report is the latest update of the Access to Success Initiative, which was established by the Education Trust and the National Association of System Heads to improve the education outcomes of minority and low-income students.
