Third year students have already completed 2 years of in class training to give them the core basic medical knowledge. Clerkship (third and fourth year) will allow them to consolidate this information and give them the hands on clinical skills to become proficient physicians.
Third year rotations are a mandatory part of the curriculum that each student needs to complete in order to graduate from medical school. The Rotation Director for each discipline (e.g. family medicine, surgery) will send you the rotation objectives that each student must fulfill during their rotation.
Fourth year elective
During fourth year of medical school, students have the opportunity to choose electives in areas that will help them with their future career plans. It is up to the students to develop their own rotational objectives and discuss them with you. Electives are a great way for students to consolidate their clinical skills to their chosen discipline and to see if they have chosen the correct career path for themselves.
