My advice, ask your assignor directly this question. A couple of years ago, my schedule seemed like a step back from previous years. I was upset. I sent an e-mail saying, "I feel like I have done something wrong." His response, "No, you are doing everything right, it was honest mistake and I forgot about you when I was scheduling." Over the course of the year, most of my JV Girls games turned into VG games, my JV Boys games went to
VB games. Where he could, he improved my schedule.
It might be a little different scenario, but I think if you simply ask, "What do I need to do to be seen as an official that you will assign X Y Z games too." You will probably get a legitimate reason and response back.
