Thanks for the replies.. I should've provided a bit more detail and mentioned that I'm dealing with Peewee aged kids right now and dealing with dilemma of segregating kids by skill set.. At the younger ages it was a no brainer to separate kids by skill as the gap was definitely noticeable, therefore, Vet88's comments above were spot on for me. However, these kids are now are older, stronger, maturer and the gap in skill level has shrunk significantly - there really isn’t anyone that is light years ahead of the next kid anymore. What I'm starting to see at this age is the variation in growth, physicality, strong on the stick and hockey sense among these kids. I also have some late bloomers that possess very strong skill sets (extremely good skaters and speedy) however, slightly less on the physicality and maturity, etc side of things..
Ive since decided to take a more simpler approach, and followed the advice of another fellow MSH'er and set aside the physical and maturity aspect of things and focused more on how well the kid can skate (edge control and strength on edge, natural ability and agility, etc.). as a measuring stick for moving kids into the more skilled groups during station based training..
