Our Story

We have a long track record of success

Our Start

National Matching Services Inc. (NMS) was founded by Elliott Peranson in 1985, after developing sophisticated matching software to place physicians into residencies in the United States.

Since then NMS has implemented Matching Programs in a number of industries and professions, including health, education, law and financial services.

Roth-Peranson Algorithm and the Nobel Prize

The Roth-Peranson matching algorithm is at the core of all our Matching Programs. The algorithm is based on the deferred acceptance algorithm, but has been adapted to accommodate complexities that arise in applying matching to real-world markets. The algorithm was designed by Alvin Roth and NMS President Elliott Peranson. It was key to Roth's winning the 2012 Nobel Prize for economics. The algorithm is stable, strategy proof, and is used in a wide variety of market design applications around the world.


NMS is the leading provider of Matching Programs for professional organizations and industry associations. We customize each Matching Program to leverage the power of the Roth-Peranson algorithm while meeting the unique needs of each recruitment environment.
