According to statistics released by the Education Trust, a national nonprofit, in 2005 UC Riverside graduated 65.3 percent of its students in six years, a figure consistent with national averages but behind the average set by the top five public research universities by as much as 22 percent. However, UCR's consistency with the national average is well above the median of 39 percent for low-income-serving institutions as calculated in 2006 by the National Center for Education Statistics, making the campus a model for successful approaches to diversity in higher education.
