The FEI Noseband Gauge's First Report Card

Ninety-five percent is the kind of number a federation likes to have in hand. It is high enough to read as vindication and low enough to sound like real measurement rather than a formality. That is the pass rate a new study has just put on the FEI's noseband measuring device, the plastic wedge that replaced a steward's two fingers as the official test of whether a bridle has been buckled too tight. The number is real, independently reported, and worth taking seriously. It is also, on its own, a much smaller finding than the sport currently wants it to be.

A second study published earlier this year, using the same device on a different sample of dressage horses, found something the pass rate cannot show: horses grow visibly more stressed as the test gets harder, and the judges scoring them largely stop noticing. Read together, the two papers say less about whether the gauge works than about what, exactly, it was ever built to catch.

The Device Behind the Number

The FEI mandated the measuring device across every discipline it governs starting 1 May 2025, ending a long-running argument about whether a steward's fingers could reliably judge noseband tightness at all. The tool itself is a small, rigid wedge, about 1.7 cm (0.7 in) tall at its highest point and 3 cm (1.2 in) wide, drawn beneath the fastened noseband and over the horse's nasal bone. If it passes freely, the noseband is legal. If it does not, the horse cannot start until the noseband is loosened. Caught too tight after the fact, in a post-competition tack check, the penalty is sharper: elimination, and a Yellow Warning Card for the rider.

That asymmetry matters more than it first appears. A pre-competition fail costs nothing beyond a minute with a buckle. A post-competition fail costs the result. Almost every horse a steward checks is checked beforehand, which means almost every failure the sport actually records is the cheap kind.

The First Report Card

The new data comes from Michigan State University professor emerita Hilary Clayton and five co-authors, published online in the Equine Veterinary Journal on 5 October 2026. The team tracked mandatory device checks across three 2025 British Dressage championships: the National Championships, the Middle Tour Championships, and the Area Festival Championships. Of 523 horses checked, 496, or 95 percent, passed on the first attempt. The other 27 failed only because the device could not be drawn beneath the noseband at all; every one of them passed once the noseband was loosened. Nobody was eliminated. The researchers also interviewed 45 riders and six stewards, and the feedback came back largely positive, welcoming a tool that replaced a subjective guess with a clear yes or no.

Taken at face value, this is a well-run rule doing exactly what it was designed to do. Riders adjusted their expectations once the standard became a hard pass or fail rather than a steward's impression, and compliance followed. That is a genuine, measurable success, and it deserves to be reported as one.

The Study Sitting Next to It

It is also a narrower success than the celebration suggests, because a separate study published eight months earlier asked a different question of the same device and got a less comfortable answer. The pilot study, led by researcher S. Fialová and colleagues and published in the journal Animals in February 2026, followed more than 200 dressage horse-rider pairs through national competitions from Elementary level up to Grand Prix, scoring noseband compliance against visible conflict behavior: mouth-opening, tail-swishing, head-tossing, and the like. Nearly every noseband in the sample was already compliant, which lines up with the pass-rate study published since. But compliance and comfort tracked two different lines entirely. Horses at the lowest levels showed a wider range of stress behaviors; horses at the highest levels showed fewer distinct behaviors but repeated them more often, with mouth-opening the most common sign across the board. Stress, in other words, rose with difficulty, not with noseband tightness, because noseband tightness barely varied at all.

The more pointed finding sits in the judging. At the lowest levels, a horse's conflict behavior correlated with a lower score. From Medium level upward, that relationship disappeared. A horse working harder, and showing it, stopped costing points once the tests got difficult enough to matter. The authors are careful to call their own work a pilot, and say plainly that it does not amount to a full welfare assessment. The direction of what it did find is still worth sitting with: the one thing the sport just finished standardizing, measuring, and celebrating is not the thing driving the behavior the sport says it cares about.

Where Show Jumping Stands

Dressage, at least, now has a season of real numbers to argue over. Show jumping does not, and that gap did not happen by accident. When the FEI opened its 2025 stakeholder consultation on the device ahead of the 2026 Jumping Rules, the International Jumping Riders Club proposed narrowing it on two fronts: checks only before competition, never after, and use of the device only when a steward already suspected a problem, rather than as a routine or random check on any horse in the ring. FEI Jumping Committee chairman Stephan Ellenbruch was reported at the time as sympathetic to the concerns, wondering aloud, in his words, whether the consultation "went a little too fast," while Rodrigo Pessoa, then the athletes' representative on that same committee, said the measure had never actually been discussed in a Jumping Committee meeting before it reached stakeholders. Those are not the hallmarks of a discipline building the infrastructure to measure itself.

Jumping's own tack and equipment rules, including its bridle and noseband provisions, are now being pulled into a standalone document that does not take effect until 1 February 2027, a full twenty-one months after the device became mandatory. No British Dressage-style compliance tally has surfaced from a major FEI jumping championship in the meantime. Closer to home, nothing in USEF's current rulebook requires the device at a standard national hunter/jumper show at all. For most of NHE's readers, the gauge will only matter the day a horse and rider cross into FEI-licensed jumper competition, whether that is a CSI, a Nations Cup leg, or a Young Rider pathway. When that day comes, the sport they are stepping into still cannot say, with British Dressage's precision, what its own compliance rate actually is.

The Metric Isn't the Welfare

None of this makes the gauge a bad idea. A hard pass-or-fail standard is a real improvement over a steward guessing by feel, and 95 percent compliance at a national championship is a legitimate marker of a rule that riders have absorbed. But a 95 percent pass rate was always the likely outcome once tightness itself stopped varying much across the field, and a number that high was never going to tell anyone whether the horses underneath those compliant nosebands were comfortable. The Fialová study suggests they often are not, and that the discomfort tracks the difficulty of what is being asked of them, not the width of a gap under a steward's wedge. A sport that wants to call the noseband question closed needs a second instrument, one that watches the horse's mouth during the test rather than the buckle before it. Show jumping, for its part, would do well to stop treating the consultation it already won as the end of the conversation, and start building the kind of dataset dressage now has, including the uncomfortable parts.
