To amend the National Child Protection Act of 1993 to ensure that businesses and organizations that work with vulnerable populations are able to request background checks for their contractors who work with those populations, as well as for individuals that the businesses or organizations license or certify to provide care for those populations.

HR 3100 amends the National Child Protection Act of 1993 to expand background check requirements. It allows businesses and organizations working with vulnerable populations (like children or elderly individuals) to request background checks for their contractors and for people they license or certify to provide care. The bill modifies the law to include individuals "contracted with" or "licensed/certified by" these organizations as those requiring background checks. This change directly affects organizations serving vulnerable groups, their contractors, and licensed care providers by broadening the scope of background checks mandated under the Act.
