The best thing to do is let your club know that you're interested in coaching. Some clubs will purchase your coaches card but most likely you will have to purchase it yourself for $35. In order to coach qualifing events you must have a bronze certification card along with the current year USA coaches card. You have to take a certification class that is roughly 6 to 8 hours long if my memory serves correct. The bronze class will run you roughly $50, but you only have pay that once.
