The ET-Extension applies to the numerical, the CR-NC, and P-N systems.
Given to undergraduate, graduate, and graduate-professional students only in courses specifically approved by the University Committee on Curriculum. Approval requires specification of the time period within which work must be completed. Courses that involve field experience or thesis work and courses in which work normally extends beyond one semester are the types of courses normally considered.
A final grade must be reported upon completion of the final course in the sequence or in the time approved for the completion of the work. If a final grade is not reported in these periods, the ET will be changed to 0.0, NC or N, depending on the grading system under which the student was enrolled.
