Life After Eckerd

Approximately two-thirds of Eckerd Biology graduates have continued with postgraduate study at many of the most prestigious medical and graduate schools in the nation. Eckerd College has been ranked near the top of all U.S. colleges and universities in terms of the percentage of its alumni who have gone on to earn Ph.D. degrees and Eckerd students have scored in the highest percentiles of the GRE and MCAT exams.
