Been looking at your posting history. You have 2 children (boy and girl) who play hockey? I am a little confused as to which (one or both) you are trying to place this year.
If it is your daughter and she is a top rate hockey player (playing tier 1 type team in NE), as long as the coach knows her talent and she is average for the school, admission is not a problem. Don't worry about the 60th percentile score. It may affect which section of a course she takes once she is there, but beyond that it is not a concern. The question is, has the coach seen her play?
As to boys and hockey, it is trickier as they are generally not as developed as young, so prospecting by coaches isn't as important because the end product is not predictable. Jr/Sr male applicants can be more accurately measured and therefore recruited.
I'm a little removed from that age hockey (mine is a college freshman who just finished 4 years at BS playing hockey), but I still recognize the quality club programs around the country (hockey is a small world). Not all great players play for the top clubs, so if she is a star on a smaller program, that will work with coaches, but the do need to see her play (they are all at the Polar Bear tourney over the holidays, so plan on being there and letting coaches know her schedule). If you are local enough, they will come out and watch her play Sundays (Saturdays are typically eaten up by their own team's games).
Hope this helps. PM if you would like to ask more questions in private.
