Princeton’s yield of students accepting offers of admission for the Class of 2018 was 69.2 percent, up slightly from 68.7 percent a year ago. Dean of Admission Janet Rapelye said the results showed “quite a lot of faith in how Princeton is handling” an outbreak of nine meningitis B cases associated with the University. At the graduate school, applications and total yield showed small drops from last year; the yield for admitted Ph.D. students continued a decline from 50 percent five years ago to 43 percent this year. “Admission continues to be highly competitive, and [there are] some trends we need to keep watching and addressing,” said Dean Sanjeev Kulkarni. He said an improving economy may be having an impact on applications and yield as more students receive “compelling job offers.”
