What Are Reversions
A reversion is a mechanism to move one or more positions that remain unfilled in the matching process from one Rank Order List (the "Donor") to a second Rank Order List (the "Receiver"), so that an attempt can be made to fill the available position(s) with applicants on the second list.
For example, a residency site offering both a pediatric program and an adult program could specify that any position that remains unfilled on the Rank Order List for the adult program should revert to the Rank Order List for the pediatric program, and an attempt should be made to fill the position(s) with additional applicants on the Rank Order List for the pediatric program. In this case, the Rank Order List for the adult program is the Donor list (because it is donating unfilled positions) and the Rank Order List for the pediatric program is the Receiver list (because it is receiving unfilled positions from the Donor list).
Similarly, a program that is submitting Multiple Lists for a single program can use reversions to move positions across lists, in an attempt to fill all available positions in the program.
