Hiring a part-time nanny means entrusting someone with your children during critical hours—background checks aren't optional extras, they're foundational to peace of mind. Whether you're bringing on a nanny for after-school care, weekend coverage, or weekday mornings, understanding what checks are standard, required, and worthwhile will help you make a safer hiring decision. This guide walks you through the background check landscape for part-time childcare providers.
Why Background Checks Matter for Part-Time Nannies
Part-time nannies often have less oversight than full-time staff or daycare facilities, which operate under state licensing rules. Your direct screening responsibility is higher. A comprehensive background check catches criminal history, substantiated abuse or neglect reports, and employment red flags that a resume alone won't reveal. The cost—typically $30–$100 per check—is negligible compared to the risk of placing your child with someone you haven't properly vetted.
Types of Background Checks to Request
Criminal Background Checks This is the baseline. Request a multi-state or national background check through a reputable screening service; don't rely on a single-state search. Part-time nannies may have moved between states, and you need visibility into their full history. Expect results in 3–7 business days.
Sex Offender Registry Search Run your candidate's name through the National Sex Offender Public Website (NSOPW) and your state's registry. This search is free and returns instantly. It's non-negotiable for anyone working with children.
Child Abuse and Neglect Registry Many states maintain abuse and neglect registries. Call your state's child protective services agency or search their online database to check whether the candidate has a substantiated history. This often catches incidents that don't rise to criminal charges.
Employment Verification and References Contact at least three references—ideally from previous families, not friends. Ask specific questions: How long did they work with you? Were there any safety concerns? Would you hire them again? Part-time nannies with solid history will have clear, positive references.
Motor Vehicle Record (if driving children) If the nanny will transport your kids, request a driving history. Look for DUIs, reckless driving, or multiple violations. Insurance companies often have affordable screening options if you're adding them to a policy.
Cost and Timeline Expectations
Screening costs vary by service and scope:
- Single criminal background check: $30–$50
- Multi-state criminal + sex offender combo: $50–$100
- Full screening package (criminal, abuse registry, DMV, employment verification): $100–$150
Most turnaround times run 3–7 days for criminal checks, though rush options (24–48 hours) cost more. Plan your hiring timeline accordingly—don't rush the screening process to fill a schedule gap quickly.
Red Flags and What to Ask
A clean background check doesn't mean you skip reference calls. Ask candidates directly about gaps in employment, reason for leaving previous positions, and how they handle conflict. Be wary of:
- Reluctance to provide references or criminal history authorization
- Vague answers about previous childcare roles
- Inconsistencies between their resume and what references report
Trust your gut. If something feels off, screen someone else.
Using Background Checks as Part of Your Hiring Process
Background checks are one layer, not the whole picture. Combine screening results with:
- In-person interviews where you assess energy, communication, and values alignment
- Trial shifts or observation periods before committing to a regular schedule
- Clear written agreements defining hours, pay, responsibilities, and your household rules

Frequently Asked Questions
Q: Can I ask a part-time nanny to pay for her own background check? It's legally permissible in most states, but many employers cover the cost to avoid liability questions and show good faith—expect to budget $50–$100 as part of hiring expenses.
Q: How often should I re-screen a part-time nanny? Annual re-screening is best practice if they're ongoing, especially for criminal and abuse registries; many families re-check every 2–3 years for long-term, trusted part-time staff.
Q: What if a background check reveals an old misdemeanor? Don't automatically disqualify; context matters—discuss it directly with the candidate, understand the circumstances and how much time has passed, and decide based on the severity and relevance to childcare.
