 Application Requirements

Prospective students applying to the Environmental Science Graduate Program complete an online application with the OSU Graduate College that includes the following:

  1. A non-refundable application fee.
  2. One original transcript from each college or university attended. For PhD applicants, the cumulative grade point average (GPA) must be 3.0 or higher. All transcripts should be scans of official transcripts showing the college’s or registrar’s original seal and any degrees completed.
  3. TOEFL/IELTS (if required to establish English proficiency). A minimum iBT TOEFL score of 79 (or 550 paper based), or a minimum IELTS overall score of 6.5 is required.
  4. GRE test score completed within the past 5 years [optional but strongly recommended for students who wish to be considered for assistantships].
  5. Current and complete resume or Curriculum Vita. For PhD applicants, this should include the citation of the completed Master’s thesis.
  6. A Goal Statement (1-2 pages) explaining how prior academic and professional experiences have prepared the applicant for graduate-level study and how the degree program will contribute to the applicant’s career aspirations and desired areas of competency.
  7. Three letters of recommendation. These should be from individuals who know the student professionally, including academic advisors and former professors who can address applicant’s academic record and potential for successful graduate-level work.
  8. An Agreement to Advise Statement from an OSU faculty member who will serve as the student’s advisor and Committee Chair; this can be in the form of an email from the advisor to esgp@okstate.edu. The applicant is responsible for contacting faculty to secure their consent to serve as advisor. A list of faculty with environmental science research interests is available under the "About Us" menu item. (Applicants to the PSM program are advised by Dr. Ken Ede.)

Financial Affidavit

The Graduate College requires a financial statement for international applicants expecting to be F1 or J1 visa holders. This Financial Guarantee documents the availability of sufficient financial resources to meet the student’s prospective educational and living expenses while in the U.S. This document must be completed before a Certificate of Eligibility (I-20 or DS-2019) can be issued.
