Satisfactory Progress

Satisfactory progress is determined through the student meeting with the Graduate Committee and includes grades, progress in supervised research, and input from the research adviser.

Grading Policy
A regular status graduate student pursuing a doctoral degree who receives one grade below B- in two program-related courses numbered 300 or above will be dropped from the program.
