Tri-Level Invitational Player Eligibility and Qualification

The Tri-Level Invitational is hosted by the USTA Southern California Section and the event has very specific player eligibility and qualification requirements. Click here to view their event website.

Please read through these items carefully, especially the parts pertaining to ratings, to ensure your team will be in compliance. These rules are coming directly from the Event Director and there are no accommodations or waivers. If you have any questions, please contact the league coordinator prior to registering your team.

  • Players with a 2024 “C” (Computer-Rating) or “A” (granted appeal up or down from a “C” rating) rated players must play at the level at which they were rostered in the 2025 season.

  • All “T” (Tournament-Exclusive), “S” (Self-Rate), “M” (Mixed-Exclusive) or “A” (non-Computer Appeal-Rated) players must play at the valid “C” (Computer-Rating) or “A” (granted appeal up or down of a “C” rating) generated after the 2025 year-end ratings are published. If they do not receive a “C” rating after the 2025 year-end ratings, they are ineligible to participate in the Invitational.

  • Should a player move up TWO LEVELS at year-end, they must play at their NEW HIGHEST LEVEL, instead of their original rostered level.

  • ​A player cannot compete in two or more NTRP divisions at the Invitational. Example: a player competing in the Low Tri division cannot compete in the Mid Tri division. Players must play on the team that they are advancing on. If a player advances on two teams, the player must declare which team they will compete for. There is no crossover or sharing of players between teams and NTRP divisions.

  • Specifically at the Invitational, players must play at-level. This means that if you are on a 4.0 team, you must have a 4.0 rating. Players MAY NOT play up in a division. For example, a 3.5 may not play on a 4.0 team.

  • For local play and at Sectionals, players MAY play up in a division. However, if your team advances to the Invitational, you will NOT be allowed to compete.
