TOEFL or IELTS Scores

  1. International applicants from non-English-speaking countries must demonstrate competency in the English language by taking either the Test of English as a Foreign Language (TOEFL) or International English Language Testing System (IELTS) exam. Dulingo does not provide sufficient proof of English proficiency. The minimum required scores are as follows:
    • TOEFL internet-based test: 79
    • IELTS exam: overall score of 6.0 and a minimum score of 5 on each subscale.
  2. Scores that are more than 2 years old are not accepted. If an international applicant has a degree from a university in an English-speaking country, the TOEFL or IELTS is not required.
  3. International applicants may apply to USU as an undergraduate student in the Intensive English Language Institute (IELI) and:
    • Take and pass the IELI placement exam, or
    • Take the IELI placement exam and complete the required classes.
  4. Note: IELI does not offer level 0 or low-beginning English classes. IELI offers level 1, which is high-beginning. Students entering IELI must have a basic knowledge of English in listening, speaking, reading, and writing. Passing the IELI placement exam or completing the required IELI classes does not guarantee matriculation into a graduate program.

Qualifying Exam

Pass a set of written examinations and an oral examination showing depth and breadth of knowledge in computer science and their area(s) of emphasis. While there is some flexibility in the scheduling of the qualifier, it is important that it be completed early in one’s program. For that reason, the following timelines are given:

  • Those without an MS must have completed 18 credits and have a 3.5 GPA in order to take the qualifier.
  • Those with an MS must have completed 12 credits and have a 3.5 GPA in order to take the qualifier.
  • Students may complete (register for) a maximum of six credits of CS 7970 (dissertation credits) before successfully completing the qualifier.

Students must complete this exam within a maximum of 24 credits or two years. Extensions beyond the 24 credits or two years require approval of the student’s graduate committee.

Qualifying Exam Policy

Financial Aid

Graduate students frequently wonder whether they can get financial assistance from the Department. This is available to qualified students in a variety of forms:

  • Fellowships provide a stipend to our best entering students.
  • Teaching assistantships provide a stipend in return for 20 hours work per week.
  • Research assistantships are awarded by individual professors who have research funds to support graduate students; consult the web pages of individual faculty to determine whether they are seeking research assistants.

In addition to the stipend, students receiving financial aid usually qualify for a waiver of up to 9 credits non-resident and resident portion of tuition. All applications need to be submitted by February 1.

Students who accept the offer of admissions by April 15 will be eligible to apply for financial aid for the following Fall semester.

Some students are able to find campus employment with other departments or research groups.

Computer Science Tuition Award Policy

Restrictions
  1. No student may receive a tuition waiver if they have been found to have violated the Computer Science Code of Conduct or the Computer Science Cheating Policy and been reported to Student Services.
  2. Students who were previously a GTA must receive satisfactory review from their previous supervisor in order to be considered for a GTA  position in future semesters.

  3. Students who are employed outside of the Department will not be awarded tuition waivers from the Computer Science Department. They will need to petition the Department where they are working.

Priorities for Tuition Awards
  1. First priority will be given to students who are supported by research grants.
  2. Second priority will be given to students selected for specific tasks by the Department.
  3. Third priority will be given to Ph.D. students and MS Plan A students who are recommended by their major professor
  4. If any tuition waivers remain, they will be assigned based on the discretion of the Department.

Constraints on Teaching and Research Assistantships
Department support is not unlimited or unconditional. The following constraints apply for both MS and Ph.D. students.
  1. If you are a Graduate Teaching Assistant (GTA), you must do well as a GTA. Consistently poor GTA reports may result in end of support.
  2. You must have a CS faculty advisor (excluding adjuncts). Department support does not go to students supervised by faculty in other departments.
  3. You must have a current CS faculty advisor. If your advisor leaves, get a new one. The advisor cannot, in general, direct from another university (exceptions are made for students who have passed the Ph.D. proposal or are otherwise nearing completion of their degree).
  4. You must continuously be making progress towards your degree in classes and research.
  5. MS students must maintain an overall GPA of 3.0 for degree-program courses and Ph.D. students must maintain an overall GPA of 3.5 for degree-program courses.
