What Are Reversions
A reversion is a mechanism to move one or more positions that remain unfilled within 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(s) on the second list.
For example, a training site offering both a general internship program and a neuropsychology program could specify that any position that remains unfilled on the Rank Order List for the neuropsychology program should revert to the Rank Order List for the general internship, and an attempt should be made to fill the position(s) with applicants on the Rank Order List for the general internship. In this case, the Rank Order List for the neuropsychology program is the Donor (because it is donating unfilled positions) and the Rank Order List for the general internship is the Receiver (because it is receiving unfilled positions from the Donor).
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.
The Difference Between Reversions and Changing the Number of Available Positions
Reverting an unfilled position within the matching process is different from deciding before the Rank Order List deadline to move a position from one program to another.
Moving a Position Before the Deadline
A training site offering multiple programs in the Match may decide, in advance of the Rank Order List deadline, to move a position from one program (e.g., because it has an insufficient number of acceptable applicants) to another program (which has many acceptable applicants). In this case, no attempt will be made to fill that position in the original program within the matching process. Training Directors can adjust the number of positions to be offered by each program in the Match at any time prior to the Rank Order List deadline using the online NMS Match System.
Reverting a Position Within the Matching Process
Reverting a position applies when an attempt is made to fill the position in the original program within the matching process but the position remains unfilled. The option to revert an unfilled position within the matching process should be used only when the final decision to move the position from one program to another cannot be made in advance of the Rank Order List deadline, but depends on whether or not the position is filled in the original (Donor) program within the matching process.
