Test Scores: 
The institution code for the University of Arizona is 4832, which you chose when you register for tests like the TOEFL or GRE. Results are sent electronically to the university, typically within two weeks of the test date. After your application is submitted, our search/match system will attempt daily to match your test scores to your GradApp record. Please make sure the name on your tests matches the name on the application to avoid missing scores. The department code is helpful but not necessary.

English Proficiency:
English proficiency is required for all applicants whose native language is not English. Applicants must submit a minimum Test of English as a Foreign Language (TOEFL) score of 550 paper-based (PB) or 79 internet-based (iBT), or an International English Language Testing System (IELTS) composite score of 7, with no subject area score below a 6. Individual departments may require a higher score and have minimum score requirements by test module. 

All applicants must submit their GRE General Test scores. No minimum score is required. GRE scores will be considered together with all other documentation submitted by applicants.

Review Process

After the application deadline passes, the faculty will review all of the applications and make recommendations for admissions. If you are recommended for admissions, the department will email you. At this time, the Graduate College may request original transcripts for verification. They will send you your actual admissions paperwork by post, or contact you by email if you are missing any items such as your degree certificate, original transcripts or financial guarantee. Applications for the fall semester application are reviewed in February and March.
