Search "English speaking nanny Bangkok" and you'll find plenty of guides on checking English fluency. But English is often not the only language question that matters for your household — and it's rarely the only one your family actually needs answered.
Start With What Your Household Actually Needs, Not What Sounds Impressive
Before you screen anyone, it helps to write down your household's real language mix. A few questions to ask yourself:
- Who does the nanny need to talk to day-to-day? You, your partner, grandparents on video calls, other household staff, the school, delivery and security staff downstairs.
- What happens in an emergency? A nanny who can explain a situation in Thai to a taxi driver, security guard, or hospital reception can matter more than one who's "conversational" in a fourth language nobody in your house actually uses.
- Is there a household staff hierarchy? Many Bangkok households run a nanny + maid + driver setup. If they don't share a working language with each other, day-to-day coordination — who's picking up whom, what the kids ate, a last-minute schedule change — gets lost in translation. Literally.
Write this list down before you start browsing candidates. It's easy to get pulled toward whoever lists the most languages on their profile, when what you actually need is someone who's solid in the two or three languages your household really runs on.
What a HelloNanny Profile Actually Tells You
Every candidate profile lists which languages she speaks, and for English and Thai specifically, you can search by proficiency level rather than a flat yes/no. Use that when you browse — filter for the languages your household needs together, instead of screening for English alone and hoping the rest works itself out.
Verifying a Language You Don't Speak Yourself
This is the part most hiring guides skip, because it only comes up once you're dealing with more than one language. If a candidate claims strong Thai, Mandarin, or another language you personally don't speak, you can still check it without guessing:
- Loop in someone who does speak it. A Thai-speaking friend, relative, or even a staff member at your condo can sit in on part of a video call and tell you afterward whether the conversation actually flowed, or whether the candidate was struggling.
- Ask her to describe something ordinary, unscripted, in that language. Her morning routine, or how she'd explain to a Thai-speaking driver that pickup time changed. Prepared one-liners ("Yes, I speak good Thai") don't tell you much — listen for hesitation or how often she drops back into English mid-sentence.
- Ask job-specific phrases, not just small talk. Can she say, in Thai, "please slow down" to a driver, or explain an allergy to a Thai doctor? Small-talk fluency and functional, situation-specific fluency aren't the same thing.
- Watch for translation-app dependence during the interview itself. Looking up one tricky word occasionally is normal. Typing full sentences into a translator to hold a basic conversation is a real gap, not just a language barrier.
Green and Red Flags
Green flags
- Comfortable switching languages mid-sentence depending on who's in the room — normal, and genuinely useful, not a sign of confusion.
- Gives specific, concrete answers about which language she used with which family members in past placements.
- Says plainly which languages she's weaker in, instead of claiming fluency across the board.
Red flags
- Claims strong ability in four or five languages with no way for you to verify most of them.
- Only ever answers in English during the interview, even when you specifically ask her to switch.
- Relies on a translation app for basic back-and-forth, not just occasional vocabulary.
A Simple Way to Plan the Interview
| Step | What to do |
|---|---|
| 1. List your household's real languages | Who talks to the nanny daily, plus emergency-use Thai |
| 2. Filter candidates on the combination you need | Not just English — the full mix your home runs on |
| 3. Bring in a speaker you trust for at least one call | Especially for a language you can't personally judge |
| 4. Ask for unscripted, situation-specific answers | Not yes/no fluency claims |
| 5. Confirm during the trial period | Watch how she actually communicates day-to-day, not just in the interview |
FAQ
Do I need a nanny who speaks every language in my household?
Not necessarily every language perfectly — but she should be able to handle the essentials (safety, schedule, daily care) in whichever language the people she interacts with most actually use. A gap in a language a grandparent uses once a month matters less than a gap in the language she needs for a hospital visit or talking to your driver.
What if the nanny I like is strong in Thai and English but not the third language we hoped for?
That's common, and often a reasonable trade-off. An occasional third language can usually be bridged with a translation app for rare situations — a daily-use language gap is the one to avoid. Weigh what comes up daily versus occasionally.
Can HelloNanny help verify a language I can't check myself?
Yes — tell us which languages matter for your household and we'll help you shortlist candidates and, where useful, sit in on part of the interview with you.
