The Geology Graduate Student Handbook describes the rules and practices specific to the department's graduate program. In it you will find the Department's philosophy of graduate education, program rules, and other information on how to successfully complete your degree. If major changes in Department requirements occur, usually students may choose to fulfill either the requirements in effect when they began graduate study, or the new requirements.
The Graduate College Handbook
The Graduate College Handbook of Policy and Requirements for Students give the rules for ALL graduate students at Illinois.
This gives campus-wide information and rules (e.g., Doctoral Committees and Examinations, and Time Limits). It is more general, whereas the Department of Geology Graduate Handbook provides information specific to the Geology program. You will consult both of these handbooks during your time here. If a conflict between the two sets of rules occurs, the Graduate College rules usually apply.
