In Texas the teams have a minimum of 7 boys and 7 girls. There are 3 lines of doubles for both girls and boys and 6 lines of singles for both boys and girls and 1 mixed doubles match. First to 10 wins. From district - 2 teams advances to regionals and from regionals 1 team advances to state so only 4 teams in each Class (5A and 4A) play for state. Lower divisions (3A, 2A, 1A) run their own state tournament that is not part of the UIL.
In Spring individual competition occurs: singles, doubles, mixed with the top two players/double teams from the regionals advancing to state for a total of 8 playing for the state title. This is a big deal and there are a lot of college coaches, even from out of state, there to watch.
A think it would be great to up the level at high schools. In Texas, the teams that win state are usually those near an academy or the most wealthy school districts or both.
To up the level we need kids to start playing in elementary school. Unfortunately most of the kids on my sons team rarely play USTA events.
Maybe more brainstorming can come up with some solutions rather than throwing up of hands and living with the status quo.
