Background checks have become a standard part of nanny hiring, and their presence in the process gives many families a sense of security that isn’t fully warranted by what the checks actually do. A background check is a useful tool. It is not a comprehensive vetting process, and families who treat it as one are skipping the steps that would tell them things the background check can’t.
Understanding what background checks actually reveal, what they’re structurally unable to reveal, and what fills the gaps, is more useful than either dismissing them as unnecessary or treating them as sufficient.
What a Background Check Actually Covers
A standard background check for a nanny candidate typically includes a criminal history search at the county, state, and federal level, a sex offender registry check, and a Social Security number verification. More thorough checks add a driving record review for candidates who will be transporting children, and some agencies add a credit check, though the relevance of credit history to childcare employment is debatable.
What this covers: criminal convictions and arrests that appear in official records, registry listings, and identity verification. A candidate who has a criminal history that wasn’t disclosed, or whose identity doesn’t match what she represented, will be caught by a proper background check.
What this does not cover: anything that didn’t produce a criminal record. Prior employment that ended badly. A pattern of short tenures that would be visible in an employment history review but not in a criminal check. Conduct in prior positions that was concerning but not criminal. References that would say something significant if properly questioned. None of this appears in a background check, and none of it is trivial information when the person being hired will spend unsupervised time with children.
The Employment Verification Gap
One of the more significant gaps in how families approach nanny vetting is employment verification, meaning actually confirming that the candidate worked where and in the role she says she did. Resumes are self-reported documents. The information on them is only as accurate as the candidate made it, and fabrications in nanny resumes, while not universal, are common enough that verification matters.
Employment verification involves contacting prior employers directly to confirm employment dates, the nature of the role, and in some cases basic information about why the employment ended. This is distinct from a reference call, which is a qualitative conversation about the candidate’s performance. Employment verification is a factual confirmation that the basic claims on the resume are accurate. Both matter. Neither is the same as a background check.
What Reference Calls Actually Add
We’ve covered reference calls in depth elsewhere, but it’s worth restating here in the context of background screening: the reference call is where the qualitative picture of a candidate fills in. The background check confirms she isn’t a criminal. The reference call confirms, or doesn’t, that she’s actually good at her job and has the qualities the family needs in someone who will be alone with their children.
A reference call with a prior employer who is willing to speak specifically about how the candidate handled the work, the children, and the professional relationship is providing information that no database can generate. The families who conduct serious reference calls alongside background checks are doing meaningfully more comprehensive vetting than the families who treat the background check as the end of the process.
What Agencies Add to This
One of the genuine advantages of working with a placement agency rather than searching independently is that reputable agencies run background checks as a matter of course and typically go further. At Seaside Nannies, the background check is one layer of a broader candidate assessment — not the end of the vetting process. A family that hires through us is getting a candidate who has been vetted across multiple dimensions, not just checked for a criminal record.
