Post-baccalaureate Research Education Programs

NIH-PREP (Biological and Biomedical Sciences)

The Post-baccalaureate Research Education Program (PREP) at Yale is a NIH-funded internship program for recent bachelor’s degree recipients to gain the research skills and academic credentials to become competitive applicants to, and successful students in, highly selective doctoral programs. PREP students conduct independent laboratory research under supervision of a faculty mentor, who is selected from among 350 faculty members in the Combined Program in the Biological and Biomedical Sciences (BBS) at Yale. PREP students also take Yale courses and participate in program-specific seminars and workshops as well as institutional training activities with beginning graduate students in the BBS. All PREP students are expected to apply to Ph.D. programs for admission to begin graduate study following successful completion of the internship.

ESI-PREP (Humanities, Social Sciences, Sciences)

The goal of the 1-year ESI-PREP experience is to provide program participants with a foundation of knowledge and skills necessary to be successful graduate students. Specific objectives for the program participants are: 1) To experience life as a graduate student at a major research university, taking courses, doing research and receiving mentoring alongside first year PhD students. 2) To study an educational curriculum that consists of research literature seminars, graduate school and career workshops, and GRE preparation. This initiative will be open to recent college graduates in all divisions (e.g. humanities, social sciences, sciences) with a strong desire to pursue a PhD, and will build upon our established NIH-funded post-baccalaureate program (NIH-PREP) in the biological sciences. Candidates must be US citizens or US permanent residents. All are welcome to apply. Recent graduates who are from backgrounds that have been underrepresented in their chosen fields of study, e.g., historically underrepresented minority students, first-generation college graduates, students from economically disadvantaged backgrounds, or women in some STEM fields, are strongly encouraged to apply.


The Yale post-baccalaureate programs are one-year in duration and run from June 15 to May 31.

NIH-PREP students spend 75% of their time conducting independent research under supervision of a faculty mentor. The remainder of the time is devoted to an educational curriculum composed of the activities listed below. ESI-PREP may devote less time to research and more time to coursework. This will be determined based on an individual development plan to be created with the director and relevant faculty.

GRE Preparation course
Graduate Workshop I
Research Literature Seminar

Fall semester:
Yale course
Graduate Workshop II
Research Presentations (Research-in-Progress)

Spring semester:
Yale course
Career Workshop
Journal Club
Research Presentations (PREP Symposium)

NIH-PREP and ESI-PREP participants receive a stipend of $27,200 for the twelve-month period for living expenses. NIH-PREP and ESI-PREP participants also receive financial support that covers tuition for one or more courses per semester during the academic year, health insurance, a GRE Preparation course administered by Kaplan Review, purchase of a laptop computer, and travel-related expenses to attend one national conference.

Participants reside in Yale campus housing for the duration of the program. Some dormitories have a mandatory meal plan. Participants will be expected to use a portion of their stipend to cover housing, the mandatory meal plan if applicable, and other living expenses.

NIH-PREP students may choose their faculty mentors from among 350 faculty members in the Combined Program in the Biological and Biomedical Sciences (BBS). ESI-PREP may similarly choose from the many faculty within their designated department or program. Please go to the department or program website for information about the faculty and their research interests. Final faculty mentor assignments are done in collaboration with the program directors.


The Yale NIH-PREP and ESI-PREP are intended for students with a strong desire to pursue research careers at the Ph.D. level. We are particularly interested in motivated and talented students from traditionally underrepresented groups and a diversity of backgrounds.

To participate in the Yale NIH-PREP or the ESI-PREP:

  • You must be a US citizen or permanent resident
  • You received your bachelor’s degree in a relevant field prior to the start of the program, but no more than 3 years prior to applying to the program
  • You are not concurrently enrolled in a degree program
  • You must apply to Ph.D. programs for admission following successful completion of the program


  • The application deadline is March 31. 
  • The application includes a personal statement, 3 letters of recommendation, and an undergraduate transcript.
  • Only applicants selected for admission will be notified directly no later than April 30.
