“ Any Licensed Coach who is certified in any context and coaches at EC sanctioned competition is not considered eligible for Amateur Status as an athlete.”
(from the EC Coaching Program Operations Guide)
The idea behind an Instructor not losing ammy status if for those truly introducing those to the sport/summer camps etc. If you are out at EC Competitions you are assumed to be either working towards or acting in the position of Competition Coach. However if coaching at local unrated shows- that is not under the EC rule umbrella.
