CAMS have published some dates for officials training this year. I'll try to keep this list up to date.
If you've helped out at club events and would like to help out further, we definitely need more event officials to get qualified. Club Chief and Bronze Scrutineer are the two categories we need most in our club events. It's also a fantastic way to get access at race meetings - e.g. state rounds or even national rounds.
