Approval for candidacy for a graduate degree by faculty action is required to establish eligibility for a degree. A graduate student may request approval by formal application after completing a minimum of 12 semester hours of graduate courses with a grade-point average of at least 3.0/4.00 (B), based on all graduate courses in residence for which final grades have been recorded. No credits are acceptable toward an advanced degree which are reported with a grade lower than C. To qualify for an advanced degree, a graduate student must have a grade-point average of at least 3.0, based on all courses completed in residence for graduate credit. To be a PhD candidate, the written qualification examinations and oral dissertation proposal are required. Each candidate for a degree must select a major subject and submit a thesis showing independent, original study in mining engineering.
