front of someone who could not perform the movement. If any traceur in the group claimed that he had completed a difficult and dangerous challenge that should not be attempted unaided, he had to prove his claims by doing the challenge again. Anyone who lied violated the principle of humility.
To join the group, new members had to be recommended by an existing member and then pass tests to evaluate their motivation for joining. Despite the huge emphasis on the collective, each traceur had to progress and develop independently— " to create the means to be yourself "— and there was a complete trust within the group. Every traceur was to encourage the others and show confidence through their behaviour. If a member violated the principles, the group could meet without the offending person to discuss various punishments. Anyone deemed unsuitable could be temporarily or even permanently banned from the group in order to uphold its disciplines and values.
