A/Composition of groups
Groups are composed depending on attending competitors and their latest wssa ranking. From this ranking, competitors are ranked following this procedure :

B/Non-ranked competitors
If in the list of competitors, there are non-ranked competitors, they will be added at the end of the list randomly.
The organisation comittee of the competition, can, if there are too many participants, and with the agreement of the judge team, organise a one or several rounds of qualifications battles for non-ranked competitors or with the weakest ranking. The winners of this qualification tournament are then aded to the final list to be added in the groups.

4/Judges

1/Table Judges :
-The ideal number of judges is 3, with a main judge (center judge) who is designated by the judge team according to his experience.
There may be only 2 judges, depending on the importance of the competition (0T+ & 1 T+) (See competition calendar)
Each judge evaluates each skater of the battle group depending on different criterias like technique, style, new tricks, quantity of tricks, speed and quality of execution, ...After each group, they make a ranking of the skaters of this group and deliberate to decide who will be qualified for the next round.
Each judge evaluate each skater of the battle group following this method : He writes down maximum of the tricks done by the skater as a reminder. The most difficult tricks have necessary to be wrote down. He can choose his own method (for example ++ or --) to specify the particularities of the realisation of the tricks (mastering, easyness, speed,..).
Judges can also use « arguments » like polyvalence to separate two skaters : example : if a skater do always same type of tricks and that another is less good on this kind of tricks but shows his technique on other types of elements, the judges may give an advantage to the one who does different tricks.

2/ Speaker :
A speaker is essential for any Battle competition.
The speaker has a very important function in the competition. He manages the time of the runs and of the groups.
He introduces each competitor and put life into the battles.
He manages the start of each competitor.
He informs each competitor on the time left in his run.
He calls next battle group and invite them to warm-up on the competition area as soon as the previous group is done.
He is always linked to the judge table to forward the informations to the public and competitors.
He announces the qualified skaters for the next round after each group.
He can comment what the skaters do to « explain » to the public, put life into the battles and look for cheers of the public.
He can support the skaters but has to stay equal not to influence the judges on one skater especially.

3/ Cone boys/girls :
At least one cone boy is needed for the good progress of the competition. The ideal number is 2. They have to take the cones hit or moved and put them back on the marks. They do it only when the skater left the line where the cones have been kicked down. They have to be very fast and precise and never stand between judges and competitors, not to trouble them.

4/ DJ :
He has to manage the music and maintain the intensity and prevent skaters to skate without music (between two musics).
He is able to accelerate rythm when the skater is in a too slow musical phase.
He is able to slow down the rythm when the skater is too slow.

5/Judgement
In a Battle group, each skater has several runs, each run is evaluated by the judges who write down what competitors do, to compare with other skaters of the group. At the end of the time for the group, the judges set up a ranking considerating what each skater has done in term of quantity and in term of quality, and comparing each skater between them. They deliberate together about the results and annouce those results before the beginning of the nest group. If the judges cannot separate 2 skaters, they can ask them to perform a last run each.

Judgement details :
The judges don't give marks to competitors, they write down all tricks they do using an abbreviation code. The « big » tricks that can be easily identified are wrote precisely (for example « HW8 » for a front Heel Wheeling on 8 cones). The simple and fast tricks sequences hard to identify precisely are wrote down like « Freestyle moments ». Pluses and minuses are added depending on the quality and average speed of the tricks and trick sequences.
The tricks done outside of the slalom course are wrote down as « OUT » and will be counted after the tricks done in the slalom in case of draw between 2 skaters.
A bonus can be given depending on the risks taken by a skater to perform special tricks.
There is no penalty for a fall or cones kicked done or non passed.
If a skater kicks down cones doing a trick or a trick sequence, he can try again until his run time is finished.
During a trick or a trick sequence, if a skater kicks down too many cones (for example 2 cones on a 4 cones trick), the judges won't take the trick into account.
During a trick or a trick sequence, if a skater falls, the judges won't take the trick into account.
If a same trick is done several times during the same run or during the runs of the same round, the judges will take into account only the best try. (example : a wheeling combo done in the first run on 4cones + 4 cones can be ameliorated by 10cones + 10cones, it is useless to do the same combo if it was already achieved, except to add another combo (for example 4+4+2, in this case it would be another trick counted by the judges)(this example is true if the skater stays on 1 wheel during all the sequence).
At the end of each group, each judge set up a ranking by skater comparing all tricks done during the group time. (Not a ranking of each run). When the ranking is done, the judges gather their results on A la fin de chaque groupe, chaque juge établit un classement comparatif par concurrent sur toutes les figures réalisées pendant le tem, if all judges agree on the same ranking, this ranking is validated, without delibaration. If judges have different rankings, a deliberation is done, taking notes of each judge who has to explain his point of view. If the judges cannot agree on a ranking, the majority (2 on 3) win the decision.
Judges can talk together during the runs and help each other, but always keep concentration on the skaters who perform their run.

Last trick :
At the end of the group, for example in semi-final & final, a last trick can be proposed by the judges (the judges have to announce it before the beginning of the group). The last trick is only one trick or transition. If a skater realises a freestyle sequence as a last trick, the judges won't take into account the content. As a last trick, the skater can repeat a same trick on as much as cone as he wants. If he stops his trick on purpose or not, he can finish his line but the judges will take into account only the first trick.
The judges can give until 3 tries to each competitor to perform his last trick, only the best try will be taken intoo account.
The last trick is used to confirm the ranking of the judges and/or separate very close skaters that could be draw.
The judges take into account only the trick identified as a last trick (the hardest), if a skater needs a « launching » trick.
