Judge Training

Updated: May 10th, 2016


Becoming an ISI Certified Judge is 100% FREE but there are some qualifications that any potential judge must meet.

As an ISI Certified Judge, ideally you would have competed in slacklining competitions in the past, have an understanding of the difficulty of tricks, be proficient with computers and maintain an unbiased attitude while judging. Maintaining an unbiased opinion can be difficult at times but that is the beauty of ISI is each trick is identified and deductions are recorded, it is easy to understand why an athlete received a particular score. The ability for a judge to be biased towards any given athlete minimized. ISI scoring are also requires multiple judges in a competition that serve to keep each other in check at all times.

As a judge, you will be responsible for the outcome of matches that athletes have trained very hard for. Sometimes there are thousands of dollars at stake, so not being accurate or fair is unacceptable.

If you are an athlete that would like to be an ISI judge you will not be required to stop competing. The only time you would not be allowed to judge a competition is one that you are competing in. We encourage athletes to become judges because who would know the current tricks and how difficult they are than current athletes.
