TrustLine Background Check For Your Nanny or Babysitter

TrustLine Background Check is a helpful tool for parents choosing a potential nanny or babysitter. Caregivers Registered with TrustLine, have no disqualifying criminal convictions, arrests or substantiated child abuse reports in California.

Applicants submit a TrustLine application and an application processing fee of $43.00, to the California Department of Social Services (CDSS), and their fingerprints to the Department of Justice (DOJ) for a fee of $64.00. When applicants fingerprint, a fingerprint scanning fee, that varies by Live Scan vendor, will be collected along with the DOJ fee. Since the Live Scan fee varies, the total fee of $143.00 dollars to go through TrustLine is approximate. This is a one-time only fee.

Some parents may feel uncomfortable talking to their caregivers about conducting a criminal history background check and requiring them to be registered with TrustLine. Remember, all child care providers who operate in State-Licensed settings, such as child care centers, have undergone a similar screening process. Employment agencies in California are also required by law to register their caregivers with TrustLine upon placement.
