ITA Rankings Explained

Understanding the ITA Rankings Algorithm (Used by DI & DII)

Introduction

The ITA Rankings Algorithm is based on an accumulation of win points and loss points, accounting for a win-loss record, the strength of schedule, and the depth/significance of wins and losses. As the season progresses, the value of each win and loss adjusts to reflect the most recent ranking of the opponent.

How do I ensure my results count towards my ranking?

All intradivisional matches from the current season will count towards your computerized ranking. For singles and doubles, all results from the current season will count for the entirety of the season, regardless of a player’s status on their team’s roster.

Coaches are responsible for confirming that all matches for their team are entered into the ITA rankings and results system correctly and in a timely manner.

The Rankings Algorithm

Σ(CountWinPts) / (#OfCountMatches + LossPts)

The ITA uses a system of countable wins, where points from your ‘X’ most valuable wins and all of your losses are factored into your ranking average. The points awarded for each countable win and loss is determined by the previous unpublished ranking run. Only teams with an intradivisional win receive an unpublished ranking; all other teams are considered to be not ranked.

Are recent results weighted heavier older results?

No, the only factor affecting the weight of a win or loss is the quality of the opponent (plus a 10% bonus for road wins) in the most recent unpublished ranking. Time does not affect the weight of the result.

Why did I drop in the rankings when I won my matches this weekend? Or why did I rise in the rankings when I lost my matches this weekend?

Since the quality of your wins is re-weighted with each ranking run, the movement of your opponents can influence your ranking. For example, if most of your win points come from 3 wins, and those opponents all move up or down the rankings one week, you will likely follow their trend the next week. If some move up and some move down, your ranking will likely stay relatively stable.

Why do only my best ‘X’ number of wins count in any given week instead of all of my wins?

Using countable wins levels the cosmic scales, so-to-speak. Not every team has the opportunity to play 20+ matches against top-50 opponents (often dependent on the conference). Countable wins account for that by only counting up to your 10 best wins, so teams can pick up points in their non-conference schedule if there aren’t many points to be won within their conference.

Why is a team with a significantly lower winning percentage ranked above me?

The Oracle ITA Rankings algorithm provides a picture of the quality of your best wins, averaged against your losses. In essence, there’s “more than one way to skin a cat.” Two teams can arrive at a very similar place by two very different methods. One can avoid picking up many losses, with a lot of average quality wins, while the other can pick up a lot of losses, but have enough very high quality wins to balance it out.

Understanding Committee-Based Rankings (Used by DI, DII, DIII, NAIA & JUCO)

Introduction

For DI & DII, the ITA utilizes regional and national committees, composed of coaches representing each region, to determine rankings leading up to the first computerized rankings (end of the fall season for singles and doubles, after National Team Indoors for teams). DIII, NAIA, & JUCO utilize regional and national committees throughout the entire season to generate their rankings.

How do I ensure my results count towards my ranking?

Coaches use the ITA rankings and results platform as a reference to generate committee based rankings. All results from the current season are considered. It is the responsibility of the coaches to ensure that their team’s results are complete and accurate.

What are the criteria for committee based rankings?

Each committee will naturally place different weight on different factors. But, all committees consider a number of factors, including, but not limited to, win-loss record, head-to-head, strength of schedule, results vs common opponents, and quality/depth of wins and losses.
