"CI-H subjects provide a foundation in general expository writing and speaking. These subjects require at least 20 pages of writing divided among three to five assignments. Of these written assignments, at least one is revised and resubmitted. CI-H subjects also offer students substantial opportunity for oral expression through presentations, student-led discussion, or class participation. In order to guarantee both sufficient attention to student writing and substantial opportunity for oral expression, the maximum number of students per section in a CI-H subject is 18, except when a subject is taught without sections (where the faculty member in charge is the only instructor). In this case, enrollment can rise to 25 if a writing fellow is attached to the subject."
