How Are the 2026 European Aquatics Championships Judged?

The 2026 European Aquatics Championships run in Paris from 31 July to 16 August and award 74 medals across five disciplines. Three of those disciplines are judged — diving, high diving and artistic swimming. Two are timed: swimming and open water swimming.

The distinction matters more than it sounds. In a judged discipline the officials produce the number that decides the medal. In a timed discipline the officials never produce a number at all — they only rule an attempt legal or illegal, and the clock does the rest.

Diving and artistic swimming both open the programme on 31 July, so the first medals of these Championships are decided by panels of judges rather than by the touchpad. High diving closes the judged programme on 7–8 August on the Seine, before the pool swimming takes over from 10 August.

Every judged discipline in Paris shares one design idea with the winter and gymnastics sports JudgeMate already covers: a difficulty value set before the athlete moves, multiplied or added to a quality mark given after. It is the same architecture as the aerials degree of difficulty table and the D-score/E-score split in artistic gymnastics.

A dive is scored by seven judges who each award a mark from 0 to 10 in half-point increments. The two highest and two lowest awards are cancelled, the three remaining awards are added together, and that total is multiplied by the dive's degree of difficulty.

The cancellation is the whole point of the panel. Because four of the seven marks are thrown away before anything is multiplied, a single judge who is unusually harsh or unusually generous cannot move the result. Where only five judges are available, one high and one low mark are cancelled instead — and three awards still survive.

Judges are told to assess starting position, approach, take-off, flight and entry, and nothing else. Under the World Aquatics diving rules a judge must specifically ignore the difficulty of the dive, the walk out to the board, and any movement beneath the surface — the splash is judged, the underwater flail is not.

The descriptive bands are written into the rules, which is why elite marks cluster so tightly. A clean dive by a European finalist is usually marked 7.0 to 8.5; anything at 9.0 or above is a judge saying the dive was close to faultless.

A dive's degree of difficulty (DD) is not a judgement. It is arithmetic, fixed in a published table before the competition starts, and every diver performing the same dive from the same height carries the same DD.

World Aquatics builds DD from five components added together: somersaults, flight position, twists, approach (including armstand take-offs on platform), and unnatural entry — the last of which credits dives where the athlete cannot see the water before entry. The heights matter too, because the same somersault count is worth different values from 3 m and from 10 m.

That is why the scoreboard can reward a worse-executed dive. A 207C (back 3½ somersaults, tuck) from 10 m carries 3.3, while a 109C (forward 4½ somersaults, tuck) from the same platform carries 3.7 — so 7.5s on the 109C beat 8.0s on the 207C.

The rules also cap what positions may be combined with what: 2½ or more somersaults with twists may only be performed in pike or tuck, and armstand dives of 2½ somersaults or more are restricted the same way. The DD table therefore closes off the arithmetic loopholes before the meet begins.

A failed dive scores zero, and the list of triggers is longer than most spectators realise. Performing a dive with a different number than announced is an automatic zero, as is taking off from one foot on a springboard, double-bouncing the board, or landing feet-first on a dive that was supposed to enter head-first.

A twist off by 90° or more at entry is also a failed dive. That single rule explains most of the shocking zeros at a European Championships: the diver completes the shape, over-rotates the twist, and the entire dive is wiped rather than merely marked down.

A balk is different from a failure. If a diver starts a running approach, stops, and restarts, the referee allows the restart but two points are deducted from every judge's award — a flat penalty applied before the cancellations, so it hits the multiplied total hard.

A dive performed in the wrong position but with the correct number is not a zero. Judges may award no more than 2 points. Where the arms are wrong at entry, or a flying position is not held through the required 90° or 180°, the ceiling is 4.5 points instead.

Synchronised diving uses eleven judges split into three jobs. Three judges score only the execution of the first diver, three score only the execution of the second, and five score only how well the pair matched. Execution judges are explicitly told to ignore synchronisation; synchronisation judges are told to ignore execution quality.

Only five of the eleven awards survive. The highest and lowest execution mark is cancelled for each diver, leaving the middle mark for each, and the highest and lowest synchronisation marks are cancelled, leaving three. Those five awards are added, multiplied by 0.6, then multiplied by the degree of difficulty.

The 0.6 factor exists purely to keep the two formats comparable. Five surviving awards instead of three would inflate synchro totals by two-thirds, so the multiplier scales them back onto the same axis as an individual dive.

Synchronisation judges are given five specific things to compare: similarity of the starting position and take-off including height, coordinated timing in flight, similarity of the vertical angle of the two entries, comparative distance from the board or platform at entry, and coordinated timing of the entries themselves. Each fault costs 0.5 to 2 points.

One quirk shapes every synchro programme: in the first two rounds the DD is assigned as 2.0 regardless of what the pair actually performs. Teams therefore save nothing by front-loading difficulty, and the medals are decided in the later, unlimited rounds.

An artistic swimming routine score is an Elements score plus an Artistic Impression score. The Elements score is built element by element from difficulty the coach declared in advance, multiplied by the judges' execution mark. Artistic Impression is a separate panel's verdict on the routine as a performance.

Ten judges officiate every routine event: five on Elements and five on Artistic Impression. They are supported by three Difficulty Technical Controllers, who verify that each declared element was actually performed, and — in duet and team events — three Synchronisation Technical Controllers, who count timing errors.

For every element, the five execution marks are trimmed the same way: highest and lowest cancelled, the middle three added and divided by three. That average is multiplied by the element's declared difficulty and by the event's published factor. Marks are given in 0.25 increments, not whole or half points.

Artistic Impression is scored on three separate marks — choreography and musicality, performance, and transitions — each trimmed the same way, then multiplied by its own factor. Unlike the execution average, the three surviving Artistic Impression marks are added, not divided, which is why Artistic Impression totals run into three figures.

Elite totals are large by design. At the 2025 World Championships the winning women's duet free routine scored 282.6087 and the winning team free routine 348.4779 — numbers that only make sense once you know difficulty and execution are multiplied, not averaged.

A base mark is artistic swimming's cliff edge. Every free hybrid is declared on a coach card with a difficulty value built from a fixed base of 0.5 plus the value of each declared movement. If the swimmers do not deliver what was declared, the whole hybrid drops to that 0.5 base — the declared difficulty is simply gone.

The trigger is strict. A declared movement that is omitted, performed differently, or performed out of the declared order collapses the element. In a duet or a team, one athlete missing the declared skill base-marks the routine for everybody, which is why a single swimmer's error can cost a medal outright.

The difficulty itself is assembled from six movement families — thrusts, spins, twists, flexibility, airborne weight and connections — with teams also earning 0.20 per pattern change, capped at six per hybrid. A hybrid declared at 10.200 that base-marks is worth 0.5: a 95% loss on that element.

Synchronisation is deducted, not scored. Three technical controllers register errors live on tablets in three severities — small (−0.1), obvious (−0.5) and major (−3.0) — the counts are averaged across the three controllers, and the total is subtracted from the Elements score. Official worked examples show a tidy routine losing −2.9 and a scrappy one losing −7.7.

World Aquatics has been narrowing when base marks apply. Laura De Renzis, vice-chair of the Technical Artistic Swimming Committee (TASC), told Inside Synchro in May 2026 that base marks are meant only for clear and obvious mistakes: controllers "need to decide whether it's there or not there, not how well it's done", and "the system was not meant to be a witch-hunt."

The 2026 Routine Factors, in force from 1 January 2026, rebalanced free routines after an analysis of 2025 competition data. Acrobatic and technical routines were left unchanged; every change lands on the free routine.

The headline is transitions. In junior and senior free routines, Artistic Impression is now split 27.5% choreography and musicality, 27.5% performance, and 45% transitions — so the connective material between the big elements now carries almost half the artistic mark. In a women's duet free routine the transitions factor is 2.3, against 1.4 each for choreography/musicality and performance.

The Elements side moved too. A solo free and a team free routine are now balanced 50% Elements / 50% Artistic Impression, while a mixed duet free routine sits at roughly 35–40% Elements against 60–65% Artistic Impression — the most artistically weighted event on the programme.

Technical routines keep their existing shape: 60% Elements, 40% Artistic Impression, with the artistic mark split 35% choreography and musicality, 30% performance, 35% transitions. An acrobatic routine remains 100% acrobatics on the Elements side.

The practical effect in Paris is that a duet which stacks enormous declared difficulty but swims flat between elements will now lose more than it did in 2025. The factors are the federation's steering wheel, and for 2026 it has been turned toward the parts of a routine spectators actually watch.

High diving is judged by seven judges who each give a single overall-impression mark, not a split into execution and entry. The two highest and two lowest are cancelled, the three remaining awards are added, and the total is multiplied by the dive's degree of difficulty.

The marking scale is the same as in the pool. High diving uses the same seven descriptive bands, so a 9.0 on the Seine means what a 9.0 means from the 10 m platform. Judges assess starting position, take-off, flight and entry — there is no "approach" to judge, because there is no run-up worth the name.

Under the World Aquatics high diving rules the programme is four counting dives, all with different numbers. Men perform one required dive capped at DD 2.8, one intermediate capped at DD 3.6, and two unlimited optionals. Women perform one required capped at DD 2.6, one intermediate capped at DD 3.4, and two unlimited optionals — a structure aligned with the men's since 2025, replacing the older two-capped-dive format.

Paris is the anomaly. World Aquatics rules set the platform at 27 m for men and 20 m for women, but the Seine event is being staged from 20 m for everyone. Gary Hunt confirmed it at the official press conference: "the dives will be from 20 metres, so it will be a surprise for many and interesting to see how everyone performs with a different set of dives than we're used to at 27 metres."

Seven metres less is about a third of a second less air time — roughly 2.3 seconds of fall against 2.0. Dives that fit comfortably at 27 m simply do not fit at 20 m, so the men's optional lists in Paris will look unlike anything at a World Championships.

Example 1 — one 10 m dive. A diver performs a 207C (back 3½ somersaults, tuck) from the 10 m platform, DD 3.3. The seven judges award 8.5, 8.0, 8.0, 7.5, 7.5, 7.5, 7.0.

Cancel the two highest (8.5, 8.0) and the two lowest (7.0, 7.5). Three awards survive: 8.0 + 7.5 + 7.5 = 23.0.

23.0 × 3.3 = 75.90 points.

Example 2 — a synchronised dive. A 3 m synchro pair performs a 109C (forward 4½ somersaults, tuck), DD 3.8, in a later unlimited round. Diver A's execution marks are 7.5, 7.0, 7.5 → the middle mark is 7.5. Diver B's are 7.0, 7.0, 6.5 → the middle mark is 7.0. The five synchronisation marks are 8.0, 8.0, 7.5, 7.5, 7.0 → cancel the high 8.0 and the low 7.0, leaving 8.0 + 7.5 + 7.5 = 23.0.

The five surviving awards total 7.5 + 7.0 + 23.0 = 37.5. Apply the synchro factor: 37.5 × 0.6 = 22.5. Then the difficulty: 22.5 × 3.8 = 85.50 points.

Example 3 — one artistic swimming hybrid. In a women's duet free routine a hybrid is declared at DD 10.200, and the event's hybrid factor is 0.3. The five element judges award 8.00, 7.75, 7.75, 7.50, 7.25.

Cancel the high 8.00 and the low 7.25. The middle three are 7.75 + 7.75 + 7.50 = 23.00, divided by three = 7.6667.

10.200 × 0.3 = 3.06, and 3.06 × 7.6667 = 23.46 points for that single element. Had the pair missed one declared movement, the same element would have base-marked to 0.5 × 0.3 × 7.6667 = 1.15 points — the difference between a medal and mid-table, from one skill.

(Note: World Aquatics manages all final difficulty values, and the published routine factors are applied per element.)
