To emphasize that the main point of my post was that Officiating has become so Standardized that one can enter the vocation without having to submit their time and effort in the classical approach towards "moving up". Really, a ref who wants to 'move up' could really waste a lot of their effective years/prime time by going the classical route. Which may not even pan out.
Pay for the camps, get the instruction from relevant clinicians, and meet assignors, impress them with practice games---and one can "move up". Now, granted you may have to travel further to get prime time games (e.g., >40 miles to get a varsity game or college level game) once you are in the network. This is the modern era way to move up in the Officiating vocation.
In my career I've seen folks who did 3rd grade girls for the ymca, then in 2 yrs they were doing hi-level JUCO games in Garden City,KS and Hutchinson, KS.

Apparently you didn't pay attention to my very first response:

There is a forum member whose son got picked up in college ball when he was 20 and attending university.
