In late spring (or early summer), the USTA publishes a new draft of the League Regulations, which will take effect the following year. The finalized rules are published in December. I have long regarded this as one of the better governance practices within organized tennis. It provides Sections, local league administrators, captains, and players with advance notice of proposed changes. Perhaps just as importantly, it creates an opportunity for unintended consequences or unforeseen implementation challenges to surface before the rules become final.
In many ways, I wish this practice extended throughout the rest of the governance structure. Too often, new local procedures simply appear with little advance notice or opportunity for thoughtful discussion. The USTA National approach recognizes that people closest to the day-to-day operation of the system frequently identify practical issues that are difficult to anticipate during the drafting process. Complex systems generally benefit from additional feedback before major changes become permanent.
Ordinarily, this site would devote a series of Wednesday Rules posts to examining the annual regulation changes. However, that day is currently occupied with my obsessive, sequential walk-through of The Code. I am reluctant to interrupt the flow. Fortunately, the changes in the 2027 League Regulations naturally fall into a three-part weekend “Unplugged” series. Each of these revolves around the common theme of subtle refinements to the way the NTRP rating system is administered and enforced.
Our topic for today is a change to the Mixed Exclusive rating coming in 2027.
The majority of USTA players have one of three rating designations. A “C” indicates a computer rating, an “S” identifies a self-rated player, and an ” A ” reflects that the rating is a result of an appeal. Less common is the “Mixed Exclusive” “M” rating. As the name suggests, these are players whose year-end rating has been established exclusively through participation in Mixed Doubles rather than single-gendered Adult divisions.
Fairly or unfairly, I have observed that many players regard an “M” rating with much the same skepticism as an “S” rating. When a player with one of those designations performs exceptionally well, the tongue wagging over ratings begins almost immediately. I am not convinced that this reputation is always deserved by either “S” or “M” rated players. Nevertheless, that perception forms important context for understanding one of the more significant changes in the 2027 regulations.
Under the 2026 League Regulations, Mixed Exclusive players occupied an unusual position within the NTRP system. Their year-end rating was generated by the normal rating process, but they were not subject to dynamic disqualification while competing exclusively in Mixed Doubles. In effect, they shared one of the same protections afforded to established computer-rated players, despite arriving at that rating through a different competitive division.
Beginning in 2027, that exemption disappears. Mixed Exclusive players will now be subject to dynamic disqualification in much the same way as other dynamically rated players.
I suspect this change reflects an effort to close what many people perceived as a loophole in the rating system. If a Mixed Exclusive player was significantly stronger than their assigned level, there was previously no performance-based mechanism to adjust that rating during the season. Whether that situation occurred frequently enough to justify a rule change is a separate question. However, the system’s architecture contained an obvious asymmetry. Similar on-court performances produced different enforcement outcomes depending on which divisions the player had competed in to earn their rating.
Like many governance decisions, this change solves the perceived problem of ratings-manipulation abuse in the Mixed divisions, but it will also increase the number of dynamic disqualifications. Mixed doubles is the most challenging type of team to captain because there are fewer options since both gender and rating levels are more tightly constrained than single-gender divisions. In other words, when those disqualifications occur, it will create increased headaches for captains.
Tomorrow, we will explore another significant change to the dynamic disqualification process, one that extends all the way to the USTA National Championships. While unrelated to the new possibility of Mixed disqualification, it is a factor that will likely further ratchet up the impact of this change.

Where can I find the 2026 version?
