I have been doing some top league u18 girls (not UK) and it can be difficult having long periods where there is no need to be an active ref
The biggest advice is not to penalize every contact. Use the slower game to think about positioning of yourself and develop your communication and confidence to make the correct decision. Like previously said, girls will tend to leave the ball at the lower levels of play until a decision is made, so make sure you have who you're going to give the ball to if neither you nor the linesman know who it came off (Attack or Defence). This isn't really a change, but with boys you can tell by body language and reaction. From experience, at most levels they will say sorry for any little knocks into each other and I found that handball is a lot more common, but that might depend on the level of play. Dissent is less likely to be received, but still use your stepped approach and the sin bin if available to use. Generally a word would fix the issue, but again the teams might be different.I'm reffing a girls' game for the first time this weekend, the age group is u16s. Should I make any adjustments to the way I would normally ref, ie would you let more go in a boys game? Any advice is appreciated.
