Application Components

Completed SOPHAS or HAMPCAS applications must be submitted by the scheduled deadline. All application materials should be sent directly to SOPHAS or HAMPCAS, including:

Letters of Recommendation

Applicants will need to submit letters of recommendation from three (3) individuals familiar with your academic and/or professional work. Letters of recommendation should be submitted online from professional, not commercial, email accounts (e.g. yahoo, hotmail, etc.).

Guidelines & Tips

  • Academic and research abilities: Reference letters should address your academic and research abilities, including your capacity to work independently, as well as your ability to comprehend, digest, and assimilate new knowledge.

  • Employment or character reference letters: These are less valuable to the admissions committee unless the employer can address your academic and research abilities.

  • Returning to school: If you have been out of school for an extended period, recommenders should include a supervisor or someone with whom you have conducted research - an individual who can touch upon your intellectual abilities and research skills - especially if in the practice of public health.

  • Undergraduate dossier service letters: These tend to be vague and general, and often fail to address the potential match between public health and the applicant.

  • Inappropriate sources: Reference letters from a peer-colleague, friend, or relative are never appropriate.

Standardized Test Scores: GRE

The Admissions Office requires applicant’s GRE scores, which should be forwarded directly from the Educational Testing Service. SOPHAS applicants use Mailman Public Health Institutional Code 2159, HAMPCAS applicants use Mailman Public Health Institutional Code 0047.

Additional information

GRE waivers are seldom granted. However, MCAT, LSAT, DAT or GMAT scores are accepted in lieu of the GRE. You should prepare for the exam. GRE preparation courses, study guides, and Internet materials can help you with the process or methodology of the exam. There are no strict cutoff scores. The average GRE scores of last year’s admitted class were:

 Old ScoringNew Scoring
GRE Verbal615159
GRE Quantitative716158
GRE Analytical/Writing4.34.3

Standardized tests that evaluate the above areas are preferred. When applicants submit tests that do not measure quantitative ability, however, the Admissions Committee looks to the undergraduate and/or prior graduate transcript(s) for a strong indication of the quantitative ability needed to succeed in your coursework.

Standardized Test Scores for International Students

International students must submit either TOEFL or IELTS scores. The minimum required TOEFL ibt score is 100 (or 600 paper based). The minimum required IELTS band score is 7.5.

TOEFL score reports should be forwarded directly to SOPHAS from the Educational Testing Service using code 5688. IELTS score reports should be sent directly to the School at the below address. Please contact the test center directly where you took the IELTS test and request that your official test score be sent to the address below. An institutional code is not required.
