Short answer is NO, Fencing is your kids own development activity, your kid should ENJOY doing it rather than doing it to PLEASE you. So the last thing you want is that your kid have the feeling that you are "FORCING" them to do Fencing.
Some parents think by benchmarking their kids with the peers is a good way to motivate them to become stronger. On the contrary, by benchmarking them will make them loose confidence and quickly lost interest in playing them. Fencing is a cyclical game of peaks, plateaus, and slumps. If you’re expecting your child to go to a champion in inter school competition within 1-2 years, you are just going to give them extra load of pressure. You should just compare kids with their own performance in recent games and not to say who is better or vice versa.
