WELCOME TO "RPI FOR DIVISION I WOMEN'S SOCCER"
This website is a resource for Division I college women's soccer coaches and fans and has four purposes:
1. One purpose is to provide information on what the Ratings Percentage Index (RPI) is, as used for Division I women's soccer. This includes providing information on how the NCAA uses the RPI in making at large selections, in seeding, and in placing teams in the bracket for the NCAA Tournament.
2. The second purpose is to provide Division I women's soccer teams' detailed RPI ratings and RPI-based information over the course of each NCAA season. This allows coaches and fans to see how their teams are doing in the RPI rating process, to see how teams' RPI ratings evolve over the course of the season, and to better understand how the RPI works in real life. RPI ratings current through the previous Sunday's games appear on the "RPI REPORTS" page by Tuesday each week, once the season has gotten through its first three or four weeks. In addition, RPI end-of-regular-season reports for previous years are available on the "Reports Archive" page.
3. The third purpose is to evaluate how well the RPI measures teams' performance. This includes evaluating the different versions of the RPI as the Women's Soccer Committee has changed it over time and trying to get a sense of what the Committee's purpose has been in making the changes. It also includes identifying changes that might improve the RPI's performance.
4. The fourth purpose is to provide information on the rules that govern the NCAA Women's Soccer Committee's at large selection, seeding, and bracket formation for the NCAA Tournament; to suggest guidelines for those who want to predict what decisions the Committee will make this year; and to provide a system for making at large selections and seeds that comes very close to matching the Committee's decisions, particularly for at large selections, and that also provides a means for analyzing the Committee's decisions from year to year. It also includes providing information to coaches for use in scheduling with a view to maximizing their teams' RPI ratings and their chances of getting NCAA Tournament at large selections and seeds.

My name is Chris Thomas. I am a retired attorney who is a nearly life-long soccer fan. I played high school and college soccer in the late 1950s and early 1960s and have played adult soccer occasionally since then. I live in Portland, Oregon and am a University of Portland women's soccer fan. I have been head coach of the St. Mary's Academy (Portland, OR) girls tennis team for almost 20 years and am assistant coach of my granddaughter's U9 soccer team.
I began studying the RPI and how the NCAA uses it for Division I women's soccer in 2006, in an attempt to understand why the Women's Soccer Committee did not select the University of Oregon to participate as an at large selection in the NCAA Tournament. I "cloned" the RPI at the beginning of the 2007 season using Excel and have done RPI calculations for Division I women's soccer teams over the course of the 2007-2012 seasons. I do my RPI work purely for the fun of it and to help build understanding, within the Division I women's soccer coaching and fan community, of the RPI and of the Women's Soccer Committee's decision-making process.
My approach is to try to provide clear, accurate, and unbiased information about the RPI and how the NCAA uses it, as related to Division I women's soccer. When I want to express my own opinion about the RPI, I try to be clear that is what I am doing. My objective is to provide information in a way that will help readers form their own independent, well-grounded understandings of and opinions about the RPI: I would rather give coaches and fans the tools they need to answer their RPI questions than have them look to me for answers. Thus although I field and answer questions from coaches and fans, in my answers I try to lay out the process I went through in arriving at the answers so that in the future, if possible, the question askers will have the tools to answer their questions themselves. There also is some information about the RPI and how the NCAA uses it that I believe to be true but cannot absolutely verify. When I provide that information, I try to remember to include appropriate disclaimers so readers will be able to make their own judgments about its reliability.
