No reason whatsoever to tell anyone that's the case. You'll turn up in uniform and most players and spectators will assume you're a qualified and experienced ref - don't make things harder for yourself by correcting them!Well done ! I am a much older person who did a couple of years as a parent reffing to help out I’ve really enjoyed it ! But I thought after only two games from around 20 I had some confrontation which made me feel inadequate as a ref as I was not qualified !!! So now I’m going to do it as I feel as an older person I have something to offer ! I’m not looking forward to doing my 5 games in uniform but not qualified ! What will reaction be????
