Here is one example I use.I put out this slalom as the test whenever confronted with a large group of mixed ability players that need to be put into equal ability groups to play a game or to be coached. The slalom incorporates lots of the aspects of the techniques required by the individual players to play the game of hockey. I.e. running with the ball, fast and controlled, changing direction with the ball pivoting, stopping the ball etc.I normally set up 2 - 4 identical slaloms, see attachment, and have 4 coaches or helpers with a stopwatch (mobile phones are great for this).To record the score I normally put a label on the stick of each player so they can write down their time. Once all players have recorded a time, ask the players to stand in time order on the sideline. Once the players are in order you can put the 10 fastest times to play a 5 aside game across 23 meter area and the next 10 in the next 23 meter area and so on up to 40 players playing on one full pitch. The last few changes you might now need to make are the players that perform better or weaker on any particular pitch (should not be to many).
