Kiplinger’s Personal Finance Magazine ranked UC Irvine 21st this year in its annual listing of the top 100 values in education nationwide. Analysts looked at freshman test scores, student-faculty ratios, graduation rates and education costs to compile the rankings, which included six other University of California campuses. Only eight campuses had a lower “student debt at graduation” number than UCI’s $13,383. More than 500 public, four-year colleges and universities are considered in the evaluation.
