    Financial Support

    Admitted Ph.D. students are typically offered financial support in the form of teaching or research assistantships, which include full tuition. Admission into this program is very competitive, though, and you must have the intention of completing this program. M.S. students are typically admitted with no financial aid. Information regarding tuition and other costs can be found from the Graduate School.

    Transfer of credits into M.S. or Ph.D. programs 

    Students may transfer up to 9 credits of graduate courses obtained from another US accredited university. The following conditions and procedure is required to transfer any credits.

    In order to be counted towards graduation, the credits must be evaluated by CME graduate director or one of our faculty members. The evaluation must establish equivalence between a course being transferred from another institution and a CME course in Stony Brook, which is accepted as part of the graduation requirements. The faculty member must be one of those who are teaching the corresponding graduate course on a regular basis. The professor typically evaluates the course materials/contents, student transcripts, etc. The approval is not automatic and we generally take a very careful look at such transfer requests.

    Graduate courses that do not meet the previous requirement can be transferred without being counted towards graduation. This can sometimes be useful because students who have earned 24 graduate credits of any kind need to be registered for only 9 credits (instead of 12) in order to have full status. Therefore, gaining this status early might reduce tuition liability.

    M.S.  to  Ph.D 

    A student in the M.S. program can subsequently apply for admission into the Ph.D. program, but should keep in mind the higher standards for entry into the Ph.D. program. The CME Ph.D. program recognize M.S. degree from other accredited US institutions, person that has M.S. degree in CME can be exempt from the mandatory course requirements for the PhD, totaling 24 credits. The student will be accepted as G5 level student and expected to complete remaining credits and requirements towards the Ph.D. degree.
