After operating the Four-Man Officiating system at the Continental Cup, European Champions Cup and the World U20 Championship at the start of the 2008 season; and taking into consideration that some nations will begin to use this officiating system in the near future and at the 2008 World Championship, the IIHF has published a Procedures Manual for the Four-Man system. The manual contains some procedures and guidelines that were implemented in the above mentioned IIHF events. This material should be useful for officiating staff members in the various countries that are looking at implementing the Four-Man system and the Directors of Officiating of national leagues and also the IIHF Game Officials.
