I feeel like I have to explain to the players why they made the team or got cut.
If you send your child to a paid camp , each player is provided an evaluation of their skills.
Very simple an evaluation is part of the cost of attending the camp.
For regular club team tryout, unless a parent/player specifically asks on why they did not make the team, suggest not providing an evaluation.
You are setting yourself up for conflict if you try and justify why a player was not chosen.
The reality is that many teams are chosen beforehand. Coaches are most times going to choose players recommended to them or players they have seen beforehand.
With shortened tryout window an evaluation is also very subjective and not true measure of the abilities of the player.
My suggestion is to call the Coaching Director for State. He can provide you standard evaluation for field players and GK's used for ODP tryouts so you do not have to go and recreate a form.
This fills your desire to provide an evaluation, however I would only provide if asked. If a parent is coming to you on why their kid did not make the team it normally is a situation where they thought their kid was better than someone chosen for the team.
