Evaluate team performance on the following criteria: team effort, intensity, concentration and aggressiveness.  Because these factors are under the direct control of the players this should be used to determine the team's performance in the drill.  What kind of errors are the players making?  Are they taking good swings but just missing, or are they backing off their game and making errors because they are afraid to make mistakes? 

Rate the perfromance of the players drill in three categories:

Excellent - All players were focused on the tasks of the drill.
Fair - Most players were focused on the tasks of the drill.
Poor - Few players were focused on the tasks of the drill.

Another way to measure performance that players may find more identifiable is to equate the performance relative to the difficulty of some opponents.  Measurement could be set up as follows:

Excellent - Effort and intensity sufficient to beat difficult competition.
Fair - Effort and intensity sufficient to beat mediocre compeition.
Poor - Effort and intenisty sufficient to beat low levels of competition only.

The evaluation should be done by the players.  The players should take responsibility for thier performance.  There are two possible outcomes when players self evaluate.  The first is the what you want to avoid and the it passive rating.  Passive rating is rating themselves high to avoid  punishment.  The second outcome is an honest representation of the level of performance. 
In order to avoid passive rating players need to feel the connection between performance and meeting overall goals.  How will this drill allow them to become better players?  How will this drill equate into success during the games?  These are questions that the players should be able to answer in order to be ableto honestly evaluate their own performance in the drills.

It is also important to recognize and allow for variation between coach and player opinion of performance.  If the team is evaluating themselves honsestly and fairly sometimes they will be higher and sometimes they will be lower than the coach's score.  The important factor is that both the groups are evaluating the correct criteria.

The evaluation of the drill is not based on the precision of execution.  The reason being there are factors possibly not under the direct control of the players that may affect the precision of execution of the drill.  Despite skill performance fluctions due to inexperience with the drill, or relative difficulty of the drill, effort and intensity are controllable aspects of drill performance.  The psychology behind the measurement of drill performance in this manner is to equate the importance of effort and intensity with performance on the court situations.  It is designed to teach players the importance of  effort and intensity, and to minimize the emphasis on uncontrollable aspects of play.

Unfortunately in order to increase the effectiveness of self evaluation for drill performance a system of punishment.  It is important that the players know how exactly they will be punished for each level of performance.  Below is an example of how to set up a punishment system for drill performance:

  Excellent:  One suicide.
  Fair:  Two suicides.
  Poor:  Three suicides.

It is important that every level of performance equates to some level of punishment.  This will increase the effectiveness of self evaluation for two reasons.  The first being that players who know that no matter what they will be doing some sort of punishment they will be more honest in thier evaluation.  The second reason is that it teaches that even at the highest level of performance there is no garauntees of success.  It is very possible to play with maximum effort and agressiveness and lose a game.

Players will be more readily honest in most situations if they know the outcome.  The players will feel they have the control over what they are doing.  The players feel the consequences of poor performance after a game.  They should also learn to feel the consequences of poor performance in a drill.  Learning the similarities will help the players learn when their performance is not good enough to put them in position to win.  It will also give them the oppurtunity to learn to recognize when performance is low and change thier own effort levels and aggresiveness. 

Players need to develop a sense of performance and the different levels.  The goal is to teach the players to recognize when the team effort is not great enough to meet the goals of the team.
