Even as its past policies on sex-abuse prevention fuel controversy, the Boy Scouts of America is hosting an unprecedented closed-door symposium Thursday with other national youth organizations, hoping to share strategies to combat future abuse.

The 10 participating groups, including the Boys and Girls Clubs of America, the YMCA and Big Brothers Big Sisters, will hear presentations from some of the nation’s top experts on child sex-abuse prevention. They also will discuss the sensitive topic of how uncorroborated information about potentially threatening adult volunteers might be shared among youth organizations.
