A co-teacher is distinguished from a guest lecturer, in that the latter generally only teaches 1-2 class sessions, and has a specialization that supplements the course requirements.
Guest lecturers may include a law librarian or a WestLaw/TWEN representative providing a refresher workshop on legal research for a course that requires a term paper. If the primary instructor is unexpectedly out 1-2 class sessions due to an illness or emergency, last-minute substitutes are generally considered guest lecturers as well.
Guest lecturers do not have to submit employment forms, and can be signed in by the primary instructor at the Security Desk. Guest lecturers arriving at the building alone should coordinate with the Law Security Desk in advance at 212.636.6975.
