2. What assistance can I receive if I can’t afford the GRE test fee?

ETS provides a GRE Fee Reduction program to domestic students and resident aliens. They also provide free test prep materials and free GRE Diagnostic Service for those retaking the GRE General Test. Please check ETS website for details.

3. When and where should I send my TOEFL/GRE scores?

Please send your TOEFL/GRE scores through ETS to us as early as possible. Purdue University’s institution code is 1631.

4. I have ordered my TOEFL/GRE test scores to be sent to your university a long time ago but my application still indicates waiting for these scores. What should I do?

Please make sure you are using the same first and last names for your application and TOEFL/GRE tests. The system cannot match your scores with your application if you are using different names. Until you submit your application and pay the application fee, TOEFL scores received will not match with your application. It will then take approximately 5 business days to be verified. We suggest that you upload test score reports to your application as miscellaneous supporting documents to help us locate your official scores.

5. Who is eligible for a TOEFL waiver?

If you received a degree within the past 36 months from a school where English is the primary instruction language in one of the recognized English-speaking countries, your TOEFL can be waived. Please check the ETS website for recognized English-speaking countries. Please contact Xiaomin Qian after submitted application so she can grant waiver to you. Please note: we also accept IELTS.

6. How can I submit recommendation letters?

You will be asked to provide your recommenders’ contact information while filling out online application. The system will send emails asking your recommenders to upload letters for you. You can’t upload letters by yourself. Your application is incomplete until all materials have been received, including recommendation letters.

7. Do I have to wait all my recommendation letters to be received and then submit my application?

No. Just be aware your application is incomplete until all materials have been received, including recommendation letters. We only review completed applications.

8. I accidentally checked the box indicating that I do not waive rights to review recommendation letters. Can you help me change my selection?

You might be able to change it before you submitting application. Once submitted, you need to contact the graduate school.

9. Can I upload transcripts downloaded from my school website to my application?

Transcripts downloaded from the website are not considered official. They have to come from the university registrar’s office. Additionally, according to the State of Indiana’s law, your social security number or other student ID similar to SSN should not appear in the transcripts. Please use a black marker to block your SSN before uploading to your application.

International applicants have to upload official transcripts in original language and in English translation.

10. Do I need to upload my bachelor’s diploma to my application?

Domestic applicants are not required to upload the bachelor’s diploma as long as their official transcripts show the degree has been awarded. International applicants will have to upload a copy of their bachelor’s diploma in original language and in English translation. If you haven't graduated and have no bachelor's diploma, please upload a provisional certificate to your application.

11. Do I have to submit a diversity essay?

It is optional. Only if you would like to be considered for recruitment fellowships, you then need to submit a diversity essay.

12. What should I include in a diversity essay?

You can describe your leadership, work experience, service experience, or other significant involvement with racial, ethnic, socio-economic, or educational communities that have traditionally been underrepresented in higher education, and how these experiences would promote a diversity of views, experiences, and ideas in the pursuit of research, scholarship, and creative excellence.  Please keep it short, ideally in one page. Please also include your US high school name and address in the beginning of your essay.

13. Are there length limitations on resume and statement of purpose?

Although the Graduate School encourages 500 words for the statement of purpose, we don’t set hard limitations and suggest you to keep them within two pages. 

14. Can I edit or add new documents to my application after submission?

Once you submitted your application, you will not be able to edit it but you can upload new materials as miscellaneous supporting documents. Please be aware if your application has been reviewed, we will not review it again even if new documents have been added.

15. How long should I wait to get an admission decision?

Time frame may vary depending on the application volume. You can login to your application account to check status. Consistent email inquiries would not speed up decision release.

16. My application has been denied. Can I find out the reasons for denial/ weakness of my application?

Reasons for denial include a number of factors, such as academic qualifications, available funding and/or enrollment limitations. Each application is reviewed and considered based on these factors. Due to the large volume of applications, we are unable to individually respond as to what weakness your application may have had. Admission decisions are final.

17. I have been admitted. When is the deadline to respond to the admission?

For on-campus programs, please respond by June 1 for fall enrollment and by November 15 for spring enrollment.

18. What kinds of funding will be provided by the school?

Funding offers are separate from admissions. Research students in MS thesis, D-PhD or PhD programs are funded with fellowships, teaching assistantships, or research assistantships. Non-thesis students in Professional Master’s and Online Master’s programs are self-funded and pay tuition by themselves.

19. How can I defer my admission?

For domestic students, you are allowed not to register courses for two semesters without deferring your admission. For example, you’ve been admitted for Fall 2020, you can wait till Summer 2021 to register. Any term longer than two semesters requires a deferral. For international students, you need to defer admission if cannot enroll in admitted term. Deferral request can be sent to Xiaomin Qian before your original admitted term starts. Each student can only defer admission once. (Please note:  if you request to defer admission, please don’t register for any courses in your originally admitted semester.  Once you register, you are considered an active student in that semester and cannot defer.)

20. What is the tuition rate for your grad program?

Tuition and fee rates may vary from year to year. Please check the Purdue Bursar’s Office website for accurate fee rates.

21. Where can I get information about your school’s health insurance?

For student health insurance coverage, cost or other questions, please contact Purdue University Student Health Center (PUSH), 765-496-3998 or email.
