For the second year in a row, the University of Washington has topped the Peace Corps’s list of colleges and universities producing the most volunteers for the international-service agency, according to a notice posted on its Web site yesterday.

Washington has 113 undergraduate alumni working overseas, followed by the University of Wisconsin at Madison with 99 and the University of Colorado at Boulder with 94. The ranking for 2008 mirrors the results from last year.

Among medium-size institutions, the University of Virginia was in the lead, with 72 alumni volunteers. The University of Chicago had the most volunteers among small institutions, with 34.

This year five institutions reached the 2,000 mark for all-time alumni volunteers: the Universities of Wisconsin at Madison, Washington, Colorado at Boulder, and Michigan at Ann Arbor, as well as Michigan State University. The University of California at Berkeley has graduated the most volunteers since the Peace Corps began, in 1961, with a grand total of 3,326. —Beckie Supiano
