Kerr's term as UC president saw the opening of campuses in San Diego, Irvine, and Santa Cruz to accommodate the influx of baby boomers. Faced with a dramatic increase of students entering college, Kerr helped establish the now much-copied California system of having the handful of University of California campuses act as 'top tier' research institutions, the more numerous California State University campuses handle the bulk of undergraduate students and the very numerous California Community College campuses provide vocational and transfer-oriented college programs to the remainder. A "Mother Jones" article mentioned that Kerr's achievements in this field earned him international acclaim.
