Students should be sure to check the particular GRE requirements for the programs that they are interested in applying to, as some have a minimum score required to apply.

Letters of recommendation are expected to be completed by a student’s previous professor or boss at a job related to public health.

Personal essays are usually expected to be anecdotal accounts of academic inspiration mixed with professional goals that can be achieved after receiving a doctoral degree.
