Although one would assume that sites like Care.com, SitterCity, Zum and UrbanSitter screen each babysitter, nanny and caregiver, the truth is, these websites aren’t obligated to do so. This responsibility, according to Care.com founder Sheila Marcelo, is the family’s. There are many companies that can be hired to complete the background screening process, but the family can also take the steps to complete a check, as well. This starts with getting the candidate’s permission to nanny background check on them and asking them for their basic identifying information, like full name, driver’s license number and address history. The next step is to order a background check from a credible provider, followed by checking the National Sex Offender Public Website (NSOPW) to flag sex offenders. The DMV in the state or states the person has lived can also provide records that may reveal reckless habits. The process could take time and money, but peace of mind can go a long way.
