What Are Reversions
It is possible within the matching algorithm to move one or more positions that remain unfilled from one Rank Order List to a second Rank Order List, so that an attempt can be made to fill the available position(s) with applicants(s) on the second list. This is referred to as "reverting" unfilled positions from one list (the "Donor") to another list (the "Receiver").
This process can be used to move unfilled positions from one program to another program, in order to fill the available positions with applicants to the second program. 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 additional applicants on the Rank Order List for the general internship. In this case, the Rank Order List for the neuropsychology program is the Donor list (because it is donating unfilled positions) and the Rank Order List for the general internship is the Receiver list (because it is receiving unfilled positions from the Donor list).
Similarly, reverting unfilled positions from one list to another can be used by a program that is submitting multiple Rank Order Lists for a single program, in an attempt to fill all available positions in the program.
Procedures for Submitting Reversions
Information and instructions for submitting reversions will be provided to training sites by December 31, 2018.
If you have questions about reversions and how they might apply to your training site, please contact NMS to discuss your situation.
Rules For Reverting Unfilled Positions
A Donor can revert some or all of its unfilled positions. It can also revert unfilled positions to more than one Receiver. For example, if Program A has 3 unfilled positions it can choose to revert its first unfilled position to Program B, its second unfilled position to Program C, and it can choose not to revert the third unfilled position to any other program.
Reversions of unfilled positions can be "chained"; for example, List A can revert unfilled positions to List B, and if some positions remain unfilled on List B, then these positions can revert to List C, and so on.
The only restriction in reverting unfilled positions is that a chain of reversions cannot "loop back" to the beginning. For example, if you request that List A revert unfilled positions to List B, then you cannot also request that List B revert unfilled positions to List A. Similarly you cannot request a chain of reversions that moves unfilled positions from List A to List B, then from List B to List C, and then from List C back to List A.
Positions that are Reverted But Not Filled in Phase I
Programs with positions that remain unfilled in Phase I of the Match must offer those positions to applicants in Phase II of the Match. When requesting the reversion of unfilled positions from one program to another, you need to consider the implications for Phase II of the Match if the reverted position(s) do not fill in the Receiver program.
For example, suppose Program A reverts all its unfilled positions to Program B, but one or more of the reverted positions does not fill in Program B. There are two options for offering the unfilled position(s) in Phase II:
- The unfilled position(s) can remain in Program B (the Receiver program) for Phase II, and Program B will participate in Phase II of the Match in order to fill the position(s) in Program B.
- The unfilled position(s) can be moved back to Program A (the original Donor program) for Phase II, and Program A will participate in Phase II of the Match in order to fill the position(s) in Program A.
When requesting the reversion of position(s) within Phase I of the Match, you must specify which program (the Donor program or the Receiver program) should offer the position(s) in Phase II of the Match if any of the reverted position(s) remain unfilled in Phase I.
