I voted no, for a couple of reasons.
1, I refuse to accept that everyone in the world can shoot one way, as the coaching manual will have you believe.
3, I refuse to sit and nod in the right places to pass an exam if I don't believe the
GNAS way is correct.
4, If somebody wants me to coach them, it is because of what they have seen me do myself as an archer and what my student can do from my help, they have faith in my ability and that would not be strengthened by a badge.
I will point out now that I am in no way, criticising registered coaches.
Whilst I do believe you do need to be able to perform at a fair level to coach with success (on the monkey see monkey do principal), I don't believe you are restricted to that level. I am a 1380+ shooter (cheers marcus

) but my coach is a 1300 shooter. What it comes down to is the experience that the coach has and that cannot be taught from a manual.
I'll also add that it is not necessary for you to be a
GNAS registered coach to coach on the
GNAS squads.
In November, 5 people were sent an invitation to coach the compound archers on the GB training squads, me, my coach and 3 others that were shortlisted through their compound experience. Only 1 (to the best of my knowledge) of the 5 is a registered coach.
