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 residency 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, 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
To request the reversion of unfilled positions from one program to another, residencies must download, complete and return a reversion request form to NMS.
The instructions must identify the Donor program, the Receiver program, and the maximum number of unfilled positions to be reverted from the Donor to the Receiver. If a single Donor program wishes to revert unfilled positions to more than one Receiver, then the sequence in which these reversions should occur must be specified.Download Reversion Request Form and Instructions
The form must be completed, signed and submitted to NMS by February 20, 2018, either as a scanned e-mail attachment to email@example.com or by fax to 844-977-0555. After sending the form to NMS, please wait at least one business hour (9:00 a.m. to 5:00 p.m. ET Monday to Friday) and then contact NMS by telephone to confirm that the form has been received and is legible.
Rules for Reverting Unfilled Positions
Please note the following rules when completing the reversion form.
A) Reporting of Unfilled Positions After the Match
Any position that is reverted from one list to another will be reported after the Match as belonging to the Receiver list to which it was finally reverted (even if the position remains unfilled on the Receiver list).
For example, suppose Program A enters the Match with 3 positions, Program B starts with 2 positions, and Program A is to revert all unfilled positions to Program B. Then if Program A fills only 1 position in the Match, the 2 remaining unfilled positions will revert to Program B. In that case, after the Match, Program A will be reported as having 1 filled position and no unfilled positions, and Program B will be reported as having 4 positions (whether or not all 4 were filled in Program B).
B) Number of Positions to Revert
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 revert its first unfilled position to Program B, its second unfilled position to Program C, but not revert the third unfilled position to any other program.
When requesting reversions from one Donor to multiple Receivers, the specific sequence in which the reversions should occur must be specified, e.g., first unfilled position to Program B, second unfilled position to Program C, etc.
C) Chained Reversions
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.
However, 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.
