Upon successful completion of required coursework and comprehensive examinations, students enroll in dissertation courses. To progress through each dissertation course, students must complete specified course objectives. If progress is made and all objectives met, students enroll in the next dissertation block. If progress is made and objectives are substantively but not fully met by the end of each course (as determined by the dissertation chair in discussion with the dissertation committee) students must enroll in a zero credit extension course (tuition based on a credit hour equivalent as defined in the Tuition and Fees Schedule in Appendix IV). If it is determined that no progress has been made, students will be required to retake the block in which no progress was made. If the student is required to retake a block due to no progress, the dissertation chair will assign a grade of No Credit (NC). A student may only receive two NC grades during the dissertation sequence. Upon receiving the third NC within the dissertation sequence, the student will be dismissed from the program. Students are required to enroll in a Dissertation course or Dissertation Extension course every session from the beginning of the dissertation until passing the final defense earning 12 semester credit hours for dissertation. Published course objectives for each dissertation course apply unless the student and dissertation committee/chair agree to and confirm in writing alternative specified objectives more appropriate for a particular dissertation topic.
