How many reference letters do I need, and who can they be from?
We do require 3 recommendations, and we are looking to hear from people who know you and your career goals/trajectory and who can speak specifically to how this program is the next logical step for you. Two must be submitted by academic recommenders, as is GSAS policy.
Your third recommendation can come from a former teacher/professor or employer, it also can be from a co-worker or a personal reference.
