Application checklist

• Start your admissions application online.
• Compose and submit a statement of purpose (1000-2000 words). We want to know about your motivations and your research interests.
• Request three letters of recommendation. Do this early to give your recommenders plenty of time to send in their letters.
• You do not need to submit an official transcript unless admitted to the program, please load your unofficial transcript directly into your application. If offered admission, then you will need to send official transcripts showing your degree earned.
• Do not submit GRE scores (General nor Subject). They are not required and will not be considered.
• English Proficiency Waiver Policy (https://gradschool.vanderbilt.edu/application-requirements/#h2-language-proficiency)
  International applicants are exempt from submitting English-proficiency scores under the following circumstances:
  • You hold a degree (bachelor’s, master’s, or doctorate) from Vanderbilt University or are currently enrolled in a Vanderbilt degree program.
  • You hold a bachelor’s degree completed in its entirety in the United States or the equivalent of a U.S. bachelor’s degree in a qualifying country. The bachelor’s degree should be earned at a regionally accredited university located in the United States, or at an officially recognized university in another country where English is both the language of instruction and the only officially recognized language of the country. This applies to institutions from the United Kingdom, Ireland, Australia, New Zealand, and Canada (except Quebec). The entire program needs to have been completed in the qualifying country. Dual-degree holders who completed just part of their degree in the U.S. or other qualifying country, and students who have transferred credits from a non-Anglophone country, do not qualify for this waiver.
  • You have completed a master’s or doctoral degree from a country in which English is both the language of instruction and the only official language. The degree needs to have already been completed at the time you submit your Vanderbilt application. Applicants who have not yet completed a qualifying master’s or doctoral program at the time they apply will still need to submit English-proficiency scores.
  • Your native language is English. This applies to native English speakers from the United Kingdom, Ireland, Australia, New Zealand, and Canada (except Quebec).
  • The language of instruction was English for the entirety of your bachelor’s degree program and the country has multiple official languages, including English. You will be prompted to provide proof that English is the official language from your institution.
    • Acceptable documentation must be one of the following:
      • Official or attested letter from the undergraduate college, university Registrar, or Controller of Examinations office.
      • Unofficial transcripts, attested mark sheets or degree statements, are also accepted if English is stated as the medium of instruction.
  • Your academic program may not override these policies, but they may choose to require an exam if you are not required to by the Graduate School.The Graduate School at Vanderbilt does not waive the English-proficiency requirement based on any other consideration such as work experience, ESL enrollment, amount of time spent in the U.S., etc. It also cannot be waived based on programs taught in English in non-Anglophone countries.Any waivers will be reviewed only once the application is submitted and all supported documents are completed, including the application fee if required.
• If you meet the Graduate School’s eligibility criteria, apply for an application fee waiver*.
• Finalize and submit your entire application by December 7, 2024.

*Note that a small number of additional waivers will be granted at the discretion of the department based on recruitment priorities and extenuating circumstances. You may request an application fee waiver directly from the department only after you have submitted your application and confirmed that a fee is due (i.e., that you are not eligible for a waiver from the Graduate School). To request a fee waiver, please email the Director of Graduate Studies for Physics, Jon Bird.
