Because these courses have regularly scheduled class meetings, unlike the 199 courses, they are highly recommended for students doing their first internship or those looking for the opportunity to explore a topic in-depth in a directed atmosphere. Most field based seminars require the instructor's consent to enroll. Seminars usually offer four units of credit and require four to twelve hours of fieldwork per week in addition to the class meetings. As with the independent internships, students must keep a weekly field journal and submit a paper or a project at the end of the quarter.
Some courses offer a pre-arranged list of sites from which to choose.
Sites may also be chosen independently.
