The resident call pool is broken down into two groups: junior call and senior call. Junior call is covered by the PGY3 class, and senior call is split between the PGY4 and PGY5 classes. A junior and a senior are always on call together. Call shifts include: 5-8 weekday shifts, 8 pm to 8 am night float shifts which are done in 7 day blocks, and day time weekend shifts.
Graded call responsibilities for junior and senior call are defined by the program.
