Evaluation is the systematic collection and analysis of data needed to make decisions. In successful coaching, players' performance and skills should be put into test and evaluated to learn about progress.
Therefore, I just thought to share information about the Goalie Checklist that the NHL Central Scouting Bureau has developed to be used by Central Scouting's full time staff to assess a draft eligible player's skill set throughout the year.
Recently, the young talent Mikko Koskinen was ranked high on the list of goalies on the basis of this very Checklist.

Apart from coach-oriented approach, this checklist certainly works also as a self-evaluation sheet.
