Elective rotations generally occurs in the PGY-3 and 4 years. The amount of elective time is variable and determined by what is necessary to achieve the goals and objectives for the proposed clinical experience, but averages 1.5 days each week for 12 months or its equivalent over the two years of training. The resident is responsible for developing an acceptable proposal to pursue elective options, and the educational method depends upon the rotation in which the resident is involved.

Through electives, residents are able to further refine their expertise in an area of interest. They may utilize this time to pursue a number of clinical electives or research opportunities. They may opt to work within the Milton S. Hershey Medical Center with any departmental faculty, or outside the facility.
