I'm a first year ref, and I was clueless as to how to go about getting 'an education.' I started out by talking with the AD at the local high school, who, three phone calls and three different people later, eventually put me in contact with a vetran official who teaches a pretty informative class. It was easy, took about 20 minutes of my time, and I'm not sure how else to do it if you don't know anything about becomming a referee (which I didn't)
