Dan, As far as the closest "instructor" being a Level 1 you might want to pass on that. I teach many L 1 instructors BUT they are VERY entry level. The L1 is really for younger kids (15 or older) that are going to be "summer camp" archery instructors. Many Level 2 instructors (18 or older) have a good working knowledge, but they too, are really entry level. They have a better exposure to teaching archery but that class is really the first one where the new "instructor" gets a first exposure to the NTS.
Like I say, many L 2 instructors are very good with a lot of experience but that might take some "shopping" to find the right one.
IF you can, try to hold out for a L3 or higher. At the L3 and higher levels they are also getting a good dose of working with individuals rather than the "group" approach for the L1 & 2s. Per USA Archery, they aren't "coaches" until L3 or higher.
