I have attended training workshops sponsored by "Friends for Youth, Inc" based in Redwood City CA. They have excellent presentations containing some very sobering statistics. Here is one presentation:

One of the quotes that sticks with me is from a cop who said 'I have investigated hundreds of predators cases involving thousands of victims. In almost every case there was a woman who said something like "I thought something wasn't right."
Friends of Youth has a paperback titled "SAFE" Screening Applicants for Effectiveness: Guidelines to Prevent Child Molestation in Mentoring and Youth-Serving Organizations" containing various tools and resources.
Other resources include a "Document Kit CD" with examples of documentation necessary to implement best practices into a mentoring program, as well as Webinairs.
A challenge for FIRST is that there is no one way a team is created and run. But there is enough literature out there to create some "best practices" examples to help teams and the adults involved do the right thing.
