The George Mason University 2005-06 University Catalog states:
Final examinations are normally given at the end of all undergraduate courses. Except in predominantly laboratory courses, exams may not be given during the last week of classes. Exams may not exceed the scheduled length of 2 hours 45 minutes. Changes in location or time of in-class final examinations must be approved by the appropriate department chair and appropriate dean. A instructor who is considering the assignment of a take-home examination or significant end of semester paper or project should inform the students at the beginning of the semester. Such assignments should be distributed by the beginning of the last week of classes so that students can coordinate them with preparation for other examinations. Students must not be required to submit examinations before the date of the regularly scheduled examination for a course. Final re-examinations are not permitted.

Instructors must give their classes a final exam of some sort, although writing instructors often nominate the final class assignment during the regular semester as the final exam. During the designated exam week (see the Schedule of Classes published each semester) instructors may not hold regular classes.
