Here in Mass. you have to get patched by the MBUA which means you have to go to a 10 week course taught by our interpretors and after a 100 question test (85) passing, and a clinic on mechanics you are authorized to work all levels of ball. most assigners of varsity and serious ball wont even look at you until you have 5 years of experience. Many boards including ours require an evaluation prior to assignment to varsity level ball or higher (legion/mens). Balls and strikes baby!!!!!
