Special Requirements

Students pursuing the thesis option will be expected to prepare a thesis based on original research. A thesis proposal will be prepared for approval by the student's advisory committee and the College of Graduate Studies before the initiation of research. The thesis proposal and the thesis will be in conformance with the guidelines and deadlines established by the College of Graduate Studies. The thesis must demonstrate the capability of the student to perform original research and to present the results obtained from such research in a clear, concise, and well-organized manner. Students pursuing the non-thesis option will take six hours of additional coursework instead of the thesis as approved by their committee.

Students pursuing the non-thesis option will be expected to undertake a comprehensive examination in the final semester of their coursework. Comprehensive exams are administered by a committee of three or more faculty whose courses have made up a significant proportion of the graduate student's studies while at Tarleton and is chaired by the adviser for their chosen concentration. These examinations are comprehensive and intensive, with an expectation of demonstration of mastery of the coursework and program.

Further information on thesis and comprehensive exam requirements can be found in the department's graduate handbook.
