Credentials vs. Chemistry: What a CV Can’t Tell You About Hiring a Nanny

A recent article in The Economist examined the booming market for nannies to the ultra-wealthy – a world of high salaries, demanding schedules, international travel and increasingly impressive candidate credentials.
Degrees. Multiple languages. Specialist training. Experience travelling with private families.
It is a fascinating look at how professionalised the top end of the nanny market has become.
But reading it, we were reminded of something we see repeatedly in recruitment:
The candidate who looks exceptional on paper is not always the candidate a family ends up choosing.
And sometimes, the person whose CV initially attracts the least attention is the one who surprises everyone when they walk into the room.
After introducing enough nannies and families, you learn that recruitment is far less predictable than a list of qualifications might suggest.
Credentials matter. Experience matters. References matter.
But there is another part of exceptional childcare that is much harder to put on a CV:
Chemistry, judgement and execution.
Because ultimately, families aren’t hiring a CV. They’re hiring someone who may become part of their everyday life.
A Great CV Is Only the Beginning
Qualifications can tell you what somebody has studied. References can tell you where they have worked. Experience can tell you what responsibilities they have previously held.
But none of those things, in isolation, tells you exactly how somebody will operate inside your home.
What happens when the baby has barely slept? When one child needs collecting from school while another needs dinner? When travel plans change at the last minute? When uniforms need finding, groceries haven’t arrived and tomorrow’s bags still need packing?
This is where exceptional private childcare becomes less about theory and more about judgement.
The best household professionals don’t simply complete a list of tasks. They understand priorities. They anticipate. They communicate. They adapt.
And, perhaps most importantly, they understand that the needs of a family rarely fit neatly inside a job description.
The Perfect CV Rarely Tells the Whole Story
One of the things you learn after introducing enough candidates to families is just how unpredictable the process can be.
Sometimes a candidate looks exceptional on paper. The experience is right, the qualifications are impressive and the CV seems to tick every box – and yet, when the family meets them, something simply doesn’t connect.
And sometimes the opposite happens.
A candidate whose CV initially seems less impressive walks into the interview and completely surprises everyone. The conversation flows. The parents feel comfortable. The candidate understands the children, asks the right questions and seems to understand how the household works.
We’ve seen this happen time and again.
It is why we encourage families not to become too attached to the idea of the perfect CV.
Of course, experience matters. References matter. Qualifications can matter enormously depending on the role.
There are also practical requirements that simply cannot be compromised.
But once the essential criteria have been met, recruitment becomes much more human.
You simply don’t know who you are going to click with until you meet them.
Many families begin their search with a very precise picture of the person they think they want. Then they interview someone slightly outside that picture and realise that the qualities they value most weren’t necessarily the ones they had written down.
The best match is often not the candidate who ticks the greatest number of boxes. It’s the person you trust. The person you can communicate with. The person who understands your household. The person your children respond to. And the person you can realistically imagine becoming part of your family’s everyday life.
That’s why we believe a shortlist should create opportunities for families to meet the right people, rather than simply present the most impressive CVs.
A CV can help us decide who is worth meeting. The interview tells us far more.
And even then, sometimes the candidate who surprises you most is the one you almost didn’t interview.
The Value of the Experienced Nanny-Housekeeper
This is one reason experienced nanny-housekeepers can be so valuable to busy families.
A well-defined nanny-housekeeper role can bridge two parts of family life that are often inseparable: caring for the children and helping the household around them function smoothly.
The exact responsibilities will differ from family to family. With babies and toddlers, childcare will naturally dominate the day. With school-age children, there may be periods when agreed household responsibilities can be completed before school collection.
A typical day might involve preparing breakfast, organising the children for school, children’s laundry and wardrobes, household errands, meal preparation, school collection, homework, activities and helping restore order before the evening begins.
None of this makes a nanny-housekeeper better than a specialist nanny, tutor, chef or housekeeper. They are different roles.
The important question is which arrangement actually suits the household.
Where Experienced Filipino Nannies and Nanny-Housekeepers Fit
At House of Yaya, we specialise in placing experienced Filipino nannies, nanny-housekeepers and household professionals.
That specialism has allowed us to meet candidates with extraordinarily varied careers. Some have worked with families in London for many years. Others bring private-household experience from Hong Kong, Singapore, the Middle East, Europe or elsewhere internationally.
Some have formal backgrounds in nursing, education or childcare. Others have developed their expertise through years of hands-on work with babies, toddlers, school-age children and complex households.
What matters to us is not making assumptions about somebody because of their nationality. It is understanding the individual candidate.
What ages have they cared for? Have they worked sole charge? Can they manage a busy school routine? How do they approach household responsibilities? Have they travelled with families? How strong are their references? How do they communicate? What kind of household brings out their best work?
And, crucially: Are they right for this particular family?
Experience Creates a Different Kind of Expertise
There are skills that can be taught in a classroom. There are others that are developed by doing the job repeatedly, in real homes, with real children and real families.
Knowing when a toddler is becoming overtired. Learning how to organise a household so mornings stop feeling chaotic. Understanding when a parent wants an update and when they simply need everything handled. Packing for children who are travelling internationally. Managing different school collection times. Remembering which uniform is needed tomorrow. Keeping calm when the day’s carefully planned schedule suddenly disappears.
These abilities don’t always produce impressive lines on a CV. But families notice them very quickly.
That is practical expertise. And in private households, it can be extremely valuable.
Credentials and Experience Shouldn’t Be Opponents
The point is not that credentials don’t matter. Nor is it that the highly qualified professionals described at the top end of the nanny market are somehow less capable.
The stronger point is that credentials and chemistry answer different questions.
Formal education can bring valuable knowledge of child development, learning, safeguarding and specialist care. Years of private-household experience can bring judgement, confidence, adaptability and practical understanding.
Neither automatically guarantees an excellent match for a particular family.
That’s why recruitment cannot simply be a CV-matching exercise.
A candidate who is perfect for one household may be completely wrong for another. The objective is to understand what the family genuinely needs and then evaluate the whole person against that role.
What Families Should Look For
When interviewing a nanny or nanny-housekeeper, look beyond the headline qualifications.
Ask about real situations. How did they manage a difficult transition with a previous child? What did a normal day look like in their last position? What happened when plans changed unexpectedly? Which responsibilities did they take ownership of without being asked? How did they communicate with parents? Why did previous roles end? What type of family environment do they work best in?
Then verify the answers through references and appropriate checks.
You’re not simply looking for somebody who can describe excellent childcare. You’re looking for evidence that they can deliver it consistently – and for someone with whom your family can build a workable, trusting relationship.
The Modern ‘Mary Poppins’
Perhaps that’s what people really mean when they talk about finding a ‘Mary Poppins.’
Not somebody who magically does everything. And certainly not somebody expected to work without boundaries.
But a professional who brings competence, warmth, judgement and calm into a household.
Someone who understands the children. Someone who understands the parents. Someone who knows what their role requires and takes genuine ownership of it. Someone the family can trust.
That quality cannot be reduced to a university name, a certificate or the number of languages listed on a CV. Nor can it be assumed because of someone’s nationality or background.
It has to be demonstrated.
Finding the Right Person, Not the Perfect CV
Many families begin their search looking for the perfect CV. In our experience, that’s rarely how the best placements happen.
The right qualifications and experience can get a candidate onto the shortlist, but chemistry cannot be written on a piece of paper.
Sometimes the candidate who appears perfect isn’t the right fit. Sometimes the person you weren’t initially sure about becomes the obvious choice after ten minutes in the room.
That’s the unpredictable – and very human – part of nanny recruitment.
You are not hiring a CV. You are hiring a person who may become part of your family’s everyday life.
At House of Yaya, our role is not to find the candidate with the longest CV. It is to understand what a family actually needs and identify experienced professionals whose background, personality, working style and practical capabilities fit that household.
For families specifically looking for an experienced Filipino nanny or nanny-housekeeper, our specialism gives us a detailed understanding of the international experience many candidates bring – while ensuring that every candidate is considered as an individual.
Because ultimately, exceptional private childcare isn’t about credentials or chemistry alone. It’s about finding someone who has the right knowledge, the right experience and the ability to put both into practice when your family needs them.
The CV starts the conversation. The meeting reveals the person. What happens in the home is what builds trust.
