Tips when Applying to Graduate School
Admission Requirements Exceptions
If you do not meet all the requirement criteria for admissions, you may still be admitted to a program. Admission in these cases is determined on a case-by-case basis. These candidates may be granted provisional status. Please inquire with the Program Director of the program you are interested in for further information.
Provisional students are admitted to this status because, in the view of the admissions committee, they do not fulfill academic requirements for admission as a degree candidate at the time of the application. Provisional students may be required to take specific prerequisite courses, and/or take a specific number of courses and complete them successfully in order to establish their eligibility to be admitted as a degree candidate.
During the time of this provisional status, students are held to grading criteria stricter than those required of degree candidates. Specifics of a provisional admission are outlined in a formal admission letter mailed to the student. All listed criteria must be met for a student to continue to enroll in courses.
Please review our Practice Math Questions page for information about our Math Exam.
Visa and Education Evaluation Requirements
Accelerated students and part-time students who have been admitted as degree candidates and who take at least three courses per semester, which is full-time classification, may request certification for an F1 visa. Students for whom this may be a possibility should indicate yes on their admissions application at the appropriate checkbox regarding initiating the visa process. The Admissions Office of the Advanced Academic Programs will assist in the certification process (firstname.lastname@example.org) which the student must complete with the Office of International Student and Scholar Services. The International Student Office is available to answer questions at 667-208-7001 or email@example.com.
Foreign Credential Evaluation
Students who earned their post-secondary degree(s) in a country other than the United States are required to have a “course-by-course” credential evaluation with GPA performed by an outside evaluation service. A number of organizations render this service. The following two credential evaluation services are acceptable: World Education Services (WES) assists students with initiating the evaluation process and can be reached at wes.org or 800.937.3895. Students may also call the WES office in Washington, DC, at 202.331.2925, where a local representative can assist them. Also, Educational Perspectives, educational-perspectives.org or 312.421.9300. Please allow four to six weeks for an official credential assessment to be completed and forwarded to the Advanced Academic Programs Admissions Office in Washington, DC.
International students whose native language is not English must take the Test of English as a Foreign Language (TOEFL). Submit results directly to the Advanced Academic Programs Office of Admissions. Please use the TOEFL code 8747. Photocopies will not be accepted. AAP requires a minimum score of 600 on the paper test, 250 on the computer-based test and 100 on the Internet-based test. For information, contact the nearest American embassy; write to TOEFL, Toefl Services, PO Box 6151 , Princeton , NJ 08541 or visit toefl.org.
No Application Deadline
Applications are accepted year-round and students may apply to enroll for Summer, Fall or Spring semesters. There are no strict application deadlines. However, it is recommended that students submit all of their application materials at least 6 weeks prior to the start of the semester (international students should apply at least 3 months before the semester starts).
