For So Cal, the 2009 Yellow Book covers everything:
http://www.socal-asa.com/jo/forms/YellowBook.pdfThe Yellow Book also answers all the questions about coaches, background checks and ACE certifications:
1. A manager, coach or team parent (team staff) that enters the field of play or dugout shall be
individually registered and background checked through the SoCal ASA mandatory
registration system. They must have a SoCal ASA authorized identification card visible on
their person at all times.
2. The manager and at least one additional adult team staff member of a team participating in
championship play shall be ACE Certified and have proof of doing so on their person. ACE
certification, which must be accomplished prior to the start of championship play, is available
online through the ASA National Office Web site.
