I'm a dad of a 12 yo lad who is slowly progressing through the bottom ages of district cricket, albeit through development squads.
To be honest, I don't thing there is any 'development' at all. He is in a development squad and what I have seen is the coaches say "good shot" in the nets but nothing about technique, nothing about poor shot selection, nothing about building innings, nothing about partnerships, nothing about putting pressure on the bat by bowling consecutive maiden overs. Maybe that will come as he progresses. I don' t know. All I know is that when I speak to other district clubs at the same age group, all the parents say the same thing, it's very ordinarily managed. At our club, there is a disconnect between the development squad and the coaches at the next level. So when my son was selected at the next level, there wasn't any consideration for his batting position, fielding position, bowling position.
Given he is 12 and if the five year blocks of play, train, compete win (if you subscribe to the Istvan Balyi structure of athlete development letting kids play and enjoy the game should be the prime focus the tactical side ( nothing about poor shot selection, nothing about building innings, nothing about partnerships, nothing about putting pressure on the bat by bowling consecutive maiden overs ) can come as you train to train

However, you'd think this is some of the stuff that should start happening from an individual perspective as part of a development squad, pulling the kid over and doing some basic batting/bowling drills and giving him something to work on personally at each session or at home with Dad.
