I am on the Creamlegbar Club board, we had a qualifying show last fall in Minnesota, we had 25 birds from 6 breeders.  We had another one in Ok.  With those we submitted our application to be admitted as a breed.  We should have our final show this fall. Which requires 50 birds and 10 breeders and the APA picks the show location not us.
And to your original question. I gave all the judges the proposed SOP's before hand along with a copy to the show Secretary and our paper work allowing us to show and be "sanctioned". That is then send to the APA.
