If I am not mistaken, anybody (head coach, assistant coach, scorekeeper) dealing directly with players in ASA must be ACE certified, which now includes some form of background check. I know at certain tournaments, these individuals must show / wear their ACE certifications. If you have questions about a particular individual working or in direct contact with your child, you need to address it with the head coach and head of the organization your daughter plays for. There is also a website (Megan's Law
http://www.meganslaw.ca.gov/ ) which you can search individuals by name or area. Any time it's dealing with YOUR child, be proactive!!!!!
