The graduation rate is an indicator of success of a college's student in attaining their educational goals. The figures are provided by the College Navigator database offered by the U.S. Department of Education. College Navigator defines graduation rate as the percentage of full-time, first-time undergraduate students. We used the latest figures available, which are of students who began their studies in the fall of 2007 and who graduated within 150% of the normal time to program completion. (For example, for a four-year program, the graduation rate includes students who graduate within six years of beginning the program.)
College Navigator did not have graduation rate figures for all of the colleges on our list. We did not, however, want to penalize those colleges without data. To that end, we simply excluded those schools from the rankings in this category.
