The Master of Science in Business Research at USC Marshall is a terminal master's degree available only to current Marshall PhD students who do not complete their PhD. It recognizes significant progress in doctoral-level coursework and research methods, providing a pathway for students who withdraw from the PhD to obtain a graduate credential. Students must complete at least 30 units of graduate-level coursework, focusing on advanced research methods and theory in a chosen business-related area. All courses must be letter-graded, numbered 500 or above, and completed in residence at USC. Admission is not available to external applicants; only current Marshall PhD students may request or be invited to receive this degree, subject to approval by faculty. 来源： https://catalogue.usc.edu/preview_program.php?catoid=11&poid=10438
