Program Specific Requirements:
  • INTERNATIONAL STUDENTS: If you have graduated or will graduate (bachelor's degree or higher) from a university in the U.S. or another country where English is the only official language, you do NOT need to submit an English proficiency exam score (e.g. TOEFL, IELTS). Your diploma will serve as a waiver if you are admitted.
  • Any supplemental documents (CV/resume, Statement of Purpose over 500 words, etc.) may be uploaded as a PDF via the online application system. We do not require a CV but it can be very helpful for the admissions committee.

The committee would still appreciate it if you can keep it concise.
  • Please do NOT mail paper copies of your transcripts, exam scores, or anything else to the Department of Statistics. Order exam scores electronically from ETS to be sent to our Office of Admissions (ISU's ETS code is 6306). You should still upload relevant copies of documents to your application.
