The application deadline for students wishing to matriculate in September is the preceding December 15. All applications must be submitted online through the Graduate Admissions portal.

A complete application will include:

  • Statement of purpose. We look for a thoughtful, well-written statement that shows the ability to overcome challenges, dedication to attain chosen goals, a capacity for creativity, an understanding of physics and/or astronomy, and any other indication of potential for research.
  • Three letters of recommendation. Recommendation letters should help us evaluate your capacity for research, the most important criterion for admission.
  • Transcripts of all previous work. Transcripts submitted with the application may be unofficial transcripts. Successful applicants who accept the offer of admission must supply an official transcript before they can begin the PhD program at JHU. In the case of students in the final year of their bachelors program, the official transcript must show completion of all coursework required for the degree.
  • TOEFL or IELTS for international students. A reproduction is acceptable. Johns Hopkins prefers a minimum score of 600 (paper-based) or 250 (computer-based) or 100 (Internet-based) on the Test of English as a Foreign Language (TOEFL).
  • $75 non-refundable application fee. The application fee may be waived.

Note: submission of General GRE and Physics GRE scores is optional.
