A background check on a youth coach could include:

•     Employment and / or volunteer verification
•     Personal reference verification
•     Education / Certificate verification
•     Sexual Predator registry
•     Criminal History Record search
•     Department of Motor vehicles record check

It is very important that organizations throughout the country perform thorough background check on all volunteer and full time personnel.  This is especially important for coaches and volunteers that have access to the youth through sports programs and other youth programs.  When it is clear to new applicants pursuing a job that gives access to the youth that an in-depth background check will be conducted on them; one that includes public records like criminal background records and other records like driving records along with employment and education verifications, in-person interview and address history trace this knowledge could prevent malfeasant applicants with a criminal past to even apply for the position.
