 The fourth year allows students to gain experience in specialties of their interest through several dozen electives.Every fourth-year student completes at least one "Acting Internship", a period in which the student assumes the role of an intern in care of patients (though a physician maintains a supervisory role).Approximately a quarter of the class takes time off between these two years to pursue a Master of Public Health degree through the UNC School of Public Health or conduct research sponsored by several institutional and national fellowships.
