Background Checks for Shanghai Nannies — A Realistic Guide

Setting expectations against the Western screening playbook:

What you can verify in the Chinese context (and what most expat families don't realize is available):

• National ID (身份证) authenticity. Trivially verifiable; partner agencies do this routinely.
• Household registration (户口本). Confirms hometown, family structure, and (sometimes) marital status.
• Health certificate (健康证). Standard for food handlers; verifiable against the issuing health bureau.
• Prior-employer references. The single most useful data point. Detailed in the reference-checks section below.
• Yuesao credentials (母婴护理师) and childcare credentials (育婴师). Tiered government-issued certifications; verifiable against the issuing body.
• Police-record certificate (无犯罪记录证明). Available but slow and depends on home-province cooperation. Detailed below.
• Pre-employment medical. Full medical including infectious-disease screening, available at any major Shanghai hospital or specialist clinic.

What you cannot reliably verify (or what Western expectations don't translate):

• Nationwide criminal-history database search. No equivalent of US public records aggregators or UK DBS-equivalent for household workers. The police-record certificate from the candidate's home province is the closest substitute and it is point-in-time, not ongoing.
• Consumer credit pull. No equivalent for household-worker screening.
• Social-media review. Possible in theory across WeChat, Xiaohongshu, Douyin, but candidates often operate quietly on these platforms and review is incomplete. Useful as a signal-check, not as a screening tool.
• International background check for foreign-national candidates. The candidate's home-country records may not be retrievable from China at all, and the families relying on a Filipino helper's prior Hong Kong or Singapore record need to obtain it before relocation rather than from Shanghai.
• Document forensics on submitted certificates. Some certifications are issued by unregulated training schools and are not meaningfully verifiable. We tell families which ones to discount.

The practical implication: the best Shanghai screening is not a single document; it is a layered structure where each layer compensates for the limits of the others.

ID and hukou verification is the foundation. Partner agencies do this for every candidate they introduce; the family should confirm with the agency that the documents have been reviewed before any interview.

National ID (身份证):

• All Chinese nationals over 16 hold one. The candidate provides her physical card; the agency takes a copy.
• Authenticity is verifiable via the Ministry of Public Security's 公民身份信息系统 (citizen-identity verification system). Agencies that operate at scale subscribe; family-direct verification is harder.
• The ID encodes: name, sex, ethnicity, date of birth, address-of-registration, ID number, photo. The ID number encodes hometown and birth date, so basic cross-checks against the candidate's stated background are easy.

Household registration (户口本):

• The booklet listing all members of a household — typically the candidate, her parents (if alive), her children, and her marital status.
• Useful for confirming hometown, parental status, and (sometimes) marital status. Some candidates do not bring the booklet to Shanghai; the agency requests it for verification purposes.
• Hukou is not portable; almost no migrant ayi or nanny has Shanghai hukou. This is normal and not a screening concern. It does matter for some practical questions (her children's schooling, her hospital access in Shanghai).

What the family should not do: hold the candidate's ID or hukou documents. The agency may take copies for its records; the family takes copies and returns the originals to the candidate. Any arrangement that involves the family holding the candidate's original documents is non-compliant and should be a hard veto.

Reference checks are the single most predictive screening tool for Shanghai nanny placements. They are also the screening tool agencies do most variably — some agencies do thorough 15–25 minute structured calls with anecdotal substance; others do 3-minute confirmations that the candidate worked there.

What a good reference check looks like:

• At least two prior employers contacted. For senior candidates with 5+ years experience, three is better.
• The call is in the candidate's working language with the prior family — Mandarin if the prior family was Chinese, English if the prior family was expat. The substance is captured in writing by the agency.
• Open-ended questions, not yes/no questions. "What was the hardest week of the placement?" produces information; "Was she punctual?" does not.
• Specific anecdotes captured. A reference that produces three specific anecdotes (sleep-regression handling, food-refusal escalation, the time the child was sick) is meaningful. A reference that produces only general adjectives is not.
• Why did the placement end? Asked of the prior family. Cross-check against the candidate's answer to the same question on the screening call. Mismatched stories are a flag.
• Would you hire her again? Asked directly. The pause before the answer is informative.

We ask agencies to send us their reference notes for review before the second interview. Notes that read "她很好，工作认真" (she's good, hardworking) without specific anecdotes get flagged and re-pulled. Roughly 20% of agency reference notes get flagged on first review; roughly half of those produce meaningful new substance on the re-pull. The other half produce a different candidate.

The 无犯罪记录证明 (no-criminal-record certificate) is available in China but is slower and more conditional than US or UK equivalents.

How it works:

• The certificate is issued by the public security bureau of the candidate's home province / city of household registration, not Shanghai.
• The candidate (or her family, with authorization) applies in person at the local police station of her hukou address. Processing time varies from 7 days to 4 weeks depending on the locality.
• The certificate confirms the absence (or presence) of criminal records in the issuing jurisdiction only. It does not cover other provinces; for migrant candidates with multi-province work history, the certificate is partial.
• Cost is modest — typically ¥ 0–50 for the issuance itself, plus the candidate's travel costs if she must return home to apply.

What the certificate actually covers:

• Criminal-court convictions within the issuing jurisdiction.
• Some administrative-penalty records (行政处罚记录), depending on the locality's interpretation.

What the certificate does not cover:

• Records from other provinces.
• Civil disputes and labor-court matters.
• Unresolved investigations.
• Anything not formally registered as a criminal record (informal disputes, allegations that didn't reach charge).

When to insist on the certificate:

• For yuesao placements with newborn-handling responsibility.
• For premium long-term placements above ¥ 18,000/month.
• For governess placements involving extended unsupervised time.
• For families where one or both parents have professional regulatory obligations that require documented screening of household staff.

When the certificate is not worth the time:

• For cleaner-only ayi roles.
• For part-time after-school ayi.
• When the reference checks have already produced a strong, specific picture and the placement is otherwise low-stakes.

The realistic timeline is 2–4 weeks from request to certificate in hand. Brief the agency at the start of the hiring process if you want it; tacking it on after the contract is signed produces friction.

The Chinese credential system for household childcare has both real government-issued certifications and a much larger ecosystem of training-school certificates that are essentially marketing material. Knowing which is which is the difference between paying for skill and paying for paper.

Real and meaningful:

• 母婴护理师 (mother-and-infant care professional). Government-recognized, tiered (one to five stars). Issued by the Ministry of Human Resources and Social Security or its delegated authorities. The four-star and five-star tiers are meaningful and verifiable; tiers one through three are entry-level and overlap heavily with training-school certificates of similar names.
• 育婴师 (early-childhood educator). Similarly tiered. The senior-level tiers carry substantive training (early-childhood development theory, infant/toddler nutrition, basic medical recognition). Junior tiers are less meaningful but still represent some standardized exposure.
• 保育员 (childcare worker). Daycare-center-level certification. Less common in Shanghai household placements but a legitimate baseline.
• Pediatric first-aid / CPR (婴幼儿急救). Various legitimate issuers including the Chinese Red Cross. Currency within 24 months matters more than the specific issuer.

Largely paper:

• Generic "nanny certificates" issued by unregulated training schools. Common, mostly meaningless.
• "Western-style cooking" certificates. Test by asking the candidate to describe a meal she would cook for an 18-month-old.
• "English-fluency certificates" from training schools. English ability is verified by conversation in the interview, not by paper.

How to verify the real credentials:

• The certificate carries a registration number (证书编号). The issuing body's database is queryable, though access is variable. Partner agencies often have direct verification relationships.
• The candidate can produce her certification record from her personal vocational-skill record (个人职业技能档案) if asked.
• For yuesao specifically, the agency should be able to confirm tier and issue date in writing. Generic "gold/silver/bronze" tier claims that don't map to a specific certification are agency-internal categories, which is fine but should be understood as such.

The yuesao service page covers the credential ladder in operational detail.

Health screening is the most standardized and easily-verifiable part of the Shanghai screening structure.

The 健康证 (food-and-hygiene health certificate):

• Standard for any candidate handling food. Issued by the local CDC (Center for Disease Control) after a screening exam.
• Covers basic infectious-disease tests including hepatitis A markers, tuberculosis (chest X-ray), bacillary dysentery screening, and a general physical.
• Renewed annually. The candidate's current certificate should be within 12 months at the start of the placement.
• Cost ¥ 60–150 depending on the issuing center; the candidate typically pays for her own.

Pre-employment medical for premium and newborn-care roles:

• A fuller medical at a major Shanghai hospital or specialist clinic. ¥ 500–1,500 depending on the panel.
• Adds hepatitis B and C, HIV serology, syphilis screening, full chest X-ray, and a general internal exam.
• For newborn-care roles, also adds varicella (chickenpox) and rubella immunity confirmation.
• The family typically pays for the pre-employment medical because they are the ones requesting the expanded panel beyond the standard 健康证.

Ongoing medical:

• Annual renewal of the 健康证 is the candidate's responsibility; the family reimburses if it's a contract requirement.
• Vaccinations the family may want documented: seasonal flu (annual, October–November), Tdap booster (every 10 years), COVID-19 boosters per current public-health guidance.

We are not a medical-advice site and do not give specific health guidance — for anything beyond the standard 健康证 and pre-employment medical structure, families should consult their pediatrician or family doctor.

Agency-mediated screening and DIY screening produce different results. For most expat families, agency-mediated is the right structure; DIY works in specific situations.

Agency-mediated screening (recommended for most placements):

• The agency handles ID verification, hukou check, reference calls, health-certificate confirmation, and (where requested) police-record certificate request.
• The agency holds the candidate's documents in trust during the placement; the family does not.
• Replacement guarantees are typically conditional on agency-handled screening. If you DIY and the placement fails, the replacement guarantee may not apply.
• Cost is bundled into the agency placement fee — typically ¥ 8,000–18,000 total for a standard role.

DIY screening (works for specific situations):

• The family handles document review, reference calls, and any health-certificate confirmation directly.
• Works well for second and third placements where the family knows the local market and has reliable references.
• Works well for friend-of-friend referrals where the prior family has already done substantial vetting.
• Carries real load — 5–10 hours of work per candidate evaluated.

Hybrid (occasional and useful):

• Agency handles initial screening; family does an additional reference call directly to a specific prior employer the family wants to talk to themselves.
• This often produces the single most valuable conversation in the entire screening, because the family-to-prior-family conversation can be candid in a way an agency-to-prior-family conversation typically isn't.

What the family-side advisory service does: audits the partner agency's screening methods quarterly, reviews reference notes per placement, and recommends when to layer DIY substance on top of the agency baseline. We do not run the checks ourselves. For a candid walkthrough of which checks make sense for your specific placement, request a consult.
