I'm going to help you see how your child is developing as a soccer player. Not how they compare to teammates. How they compare to who they were a few months ago.
I'll ask a handful of questions about what you actually see at games and training. You don't need to know soccer terms, and "I don't know" is a fine answer. It takes about ten minutes, and you'll get a snapshot at the end.
To start: how old is your child, where do they play (rec, travel, club), what position do they usually play, and what made you want to run this today?
