A star prefixed to the title of a course in the YCPS indicates that permission to enroll in the course must be secured in advance from the instructor. Seminars, because they are characterized by limited enrollment, are all starred. An instructor may also limit enrollment in other courses after appropriate consultation with the department. Since students assume that a course listing in the YCPS without an indication of limited enrollment means that the course is available to all students, it may be necessary, and it is certainly prudent, that course listings indicate whatever limitations in enrollment exist. In addition to the YCPS star, courses may indicate limited enrollment through a listing of prerequisites, a statement about the number of students who may be admitted to the course, a declaration that the course is open only to majors, or a statement specifying that the course is open, for example, only to juniors and seniors.
The Registrar's Office does not, student by student and schedule by schedule, verify that a student has received permission from an instructor to enroll in a limited-enrollment course. If the name of any student who does not have the instructor's permission to take a course appears on the class list, the instructor should notify the Registrar's Office to drop the student from the course. Similarly, the Registrar's Office does not check whether or not a student has met the prerequisites for a course. It is up to the instructor to ascertain that a student has the appropriate preparation.
