The Princeton Economics department supports students who study abroad. But because the study of economics is sequential (courses must be completed in a particular order), students need to plan well ahead and carefully to spend a semester or year abroad. The best times for economics majors to study abroad are Sophomore Spring and Junior Spring. Only participants on the Study Abroad Program may take economics courses outside of Princeton for departmental credit. You must seek preapproval for these; ex post facto approval is never granted.
