To become an official measurer for Boone & Crockett, you need to apply for and be accepted for their five-day training program. Your chances for being accepted are better if there aren't any official measurers in your area. At one time I was really close to sending in my application, but I came to the realization that this hunting is about much more than scores and numbers, and I didn't want to invest so much of my time in the whole deal. I did buy the scorer's manual, though, and trained myself on how to measure antlers properly.
