Acting Internship

An acting internship (sub-internship) of four-week duration is required during the senior year. An AI is a clinical rotation offered on an in-patient service in which one or more attending physicians have overall responsibility for coordinated patient care. The service will be structured with both attending staff and house staff.

The acting internship should include the assignment to the student of specific groups of patients upon whom he or she completes an initial history and physical examination, constructs a differential diagnosis, formulates a treatment plan, writes orders, and carries out necessary therapy, all under careful supervision.

Acting internships that fulfill this requirement are offered in:

Search the Course Catalog for more information on Acting internships.

Acting internships in other departments or out of the city will not fulfill the AI requirement.


Integrated Life Science Course

The fourth year Integrated Life Science (ILS) Program includes a choice of courses that revisit some aspect of basic science after students have had several years of clinical experience. Because of the level of sophistication that students have developed by this stage in their medical education, they can better understand the relevance of basic science to clinical problems.  Each student is required to complete one ILS course. 

ILS Courses

Boot Camps that fulfill this requirement are offered in:

  • Emergency Medicine
