Delaware WTT Rules & Regulations

What is World TeamTennis?

World TeamTennis (WTT) is co-ed teams competing in a format that consists of 6 no-ad sets that are played to 6 games. This allows men and women to compete in an exciting fast-paced format.

What is a WTT team?

WTT gives you a chance to play singles, doubles and mixed doubles as part of team. WTT uses rules that include player substitutions at any time, cumulative game scoring and a fast paced format that keeps the action rolling! Teams are encouraged to coach and support from the sidelines. It's about competition, but laced with huge doses of fun and good sportsmanship.

Format - Matches are a round robin format. Teams consist of a minimum of two (2) men and two (2) women with a maximum of ten (10) players per team.

There must be at least 4 teams in each level. The number of matches played depends on the number of teams.

Who can play?

Adults (18 & over) may sign up as a team or as an individual.

What Divisions (levels of play) are offered?

WTT uses the USTA rating system. We are accepting registration at the 3.0 division, 3.5 division, 4.0 divison and hopefully a 4.5 Division.

If there is enough of a demand, we will add senior divisions. Please email us at if you would like to play on a team in the senior division.

Determining Team Rating

The average NTRP rating of the top two men and top two women players on your team determines the team rating.


            Joe- 4.5                                Mary- 3.5

            Tom- 4.5                              Jill-3.5

            Bill- 4.0                                 Gail- 3.5

            Joe- 4.5                                 Mary- 3.5

             Jim- 3.5                                Joan- 3.0

The best two men and two women are: 4.5 + 4.5 + 3.5 + 3.5 = 16. 16 divided by 4 equals 4.0.

This team could register for the 4.0 division or a higher division. A team consists of a minimum of two men and two women. Although the limit to the number of team members is ten, the suggested number of players is three men and three women.

Can I register as an individual/substitute/team?

You can register as an individual who needs a team, as a group of individuals who want to play together (please make a note in the comment section who you want to be placed with) or a complete team (please make a note of the players on your team). If you are captain of a team and would like that team to be included in the drop down menu on the registration form, please email Taya or Alison at

If you register as an individual needing a team, please realize that we will not contact you regarding your team assignment until after all registrations are in. Please be assured that we will contact you and you will be assigned a team, so keep the dates open and plan on playing.

If you are joining an established team you will be able to identify that team as part of the registration process. When we form new teams to accommodate everyone, one of the players must be willing to be captain.

Note to substitute players:

Substitute players must be approved by the local league coordinators before playing in a match, can pay a reduced fee and are only allowed to play in one match. If a sub plays in more than one match they are subject to the full league fee as they are now eligible to play for that team at National Qualifier events and Nationals.

Why register via the Internet?

You are not an official league participant until you have registered online. When you register via the Internet site you will be e-mailed league information during the season and your WTT Member Benefits (WTT Point of Contact Newsletter, discounts on hotel, rental cars, 2 for 1 tickets, plus more).

League winners qualify for a National Qualifier?

Winning teams advance to the WTT National Qualifiers. Your team is eligible to participate in a NQ for up to one year from the end date of your league. For every four (4) teams in any official World TeamTennis (WTT) local league division, one (1) team will be eligible to participate in a NQ.
