eNannySource has been chosen as the best background check service to screen household employees, such as nannies, senior caregivers and housekeepers. Some of the top features include budget-friendly pricing, transparent screening details and great customer service. Various plans include criminal records and national sex offender registry searches, county court records searches, driving record reports and personality assessments. Reports are delivered in easy-to-read PDF format, which indicates whether something negative was found. A possible downside of the service, however, is that the company cannot be reached by phone.
