Class registration is required to take the qualifying examination.

Students must be admitted to the ECE graduate (PhD or Master) program on a full standing status with the Graduate College in order to appear for the qualifying examination.

Students who pursue a PhD degree part-time are required to appear for the qualifying exam in the semester following registration of 24 PhD semester credit hours (including independent study courses and ECE 599). This requirement is equivalent to two semesters of full time course work.

Master's students in ECE may petition to appear in the qualifying examination if they have completed at least one calendar year of residence and have a GPA of 3.5 or higher.

Students are required to pass area examinations in two areas.

Students may sit for the qualifying exam a maximum of two times. Second attempts must be made in next consecutive offering of the examination.

Students who pass any area of the examination during the first attempt are not required to re-take that area in the subsequent examination.

Students may elect to take one or two area examinations during the first attempt. Students are not allowed to register for extra areas other than the number required during the second attempt.

Students must register for the examination in Room 1020 SEO by the registration deadline. You must specify the areas at the time of registration.

Students must make their first attempt in the first April after their first semester of enrollment. If a second attempt is needed, it must be made at the next consecutive exam date. Students who fail to pass two areas after their second sitting will be expelled from the graduate program. Students who fail to appear for the exam in the first April after their first semester of enrollment will be expelled from the graduate program.

Each area of the examination lasts two hours.

Areas of the examination are based on upper-level undergraduate and beginning graduate level materials.

Exam questions are based on a publicly announced list of required topics and suggested reading materials, rather than specific ECE courses.

Students are to remain in the examination room during the 15 minute intervals between examination periods.

Students are to leave their notes and other reading material at a designated place in the examination room before the start of the examination. Students will not have access to this material during breaks.

All examinations are closed book. Students are permitted to bring a scientific calculator and no programmable calculators are allowed. Cell phone use in the examination room is not allowed.

The order of the papers is determined by the Director of Graduate Studies prior to the exam date. It will be revealed on the exam date by the faculty and staff supervising the examination.

Students are required to return their examination paper, answer book, and scratch paper at the end of each examination period.

Any student who leaves the examination room unescorted will not be allowed to return and complete the remainder of the examination.

Each student is assigned a code number for the qualifying examination. She or he must not write his/her name or social security number anywhere on the examination paper, answer book, or other papers used in the examination. The code number is the only form of identification that should appear on any testing materials.

Each student's area examination will be judged as having passed or failed, and a numeric score reported. Area subcommittees must provide the results of the area examinations within ten calendar days of the examination to the Director of Graduate Studies.

Two weeks after the examination, the Graduate Committee reviews the exam results for the purpose of maintaining approximate uniformity across content areas. The Graduate Committee will modify content area subcommittee pass/fail decisions in extreme cases only.

The Director of Graduate Studies notifies students of the examination results on the first business day following the Graduate Committee meeting. A letter will be sent to the student's current address.

Appeals related to the grading or results of the exam should be made by the student's advisor to the Director of Graduate Studies. The DGS will present the appeal to the Graduate Committee for reconsideration and possible re-evaluation.
