Choosing an au pair from multiple candidates can feel overwhelming—you're not just hiring childcare, you're inviting someone into your home and trusting them with your family's daily life. A structured decision matrix removes emotion from the process and ensures you're comparing apples to apples across all your candidates. Here's how to build and use one that actually works.
Why You Need a Decision Matrix
Reviewing five or ten au pair applications in your head creates decision paralysis. You'll remember that one candidate had great references but forget what the other said about her experience with toddlers. A decision matrix forces you to score every candidate on the same criteria, making trade-offs visible and defensible—especially important if you're deciding with a partner.
Identify Your Non-Negotiable Criteria
Before you start evaluating, list the absolute requirements for your situation. These typically include:
- Age range and visa eligibility for your country
- Minimum childcare experience (months or years, specific age groups)
- Language fluency (yours, or a language you want your children exposed to)
- Availability and start date alignment
- Willingness to commit to your contract length (usually 12 months)
- Valid CPR/first aid certification, or willingness to obtain it
Any candidate who doesn't meet these should be eliminated before you build your full matrix. No point scoring someone on personality if they can't legally work in your country.
Build Your Scoring Categories
These eight categories cover what matters most to host families:
- Childcare experience (0-25 points)
- Prioritize direct experience with your children's specific ages over general childcare
- Communication skills (0-15 points)
- Can they articulate ideas clearly in conversations or written submissions?
- References quality (0-20 points)
- Contact at least two previous host families; look for specific stories, not just "great"
- Reliability and responsibility (0-15 points)
- Punctuality, handling of prior commitments, how they describe their reliability
- Cultural fit and personality (0-10 points)
- Does their lifestyle align with yours? (Active vs. relaxed, formal vs. casual, values match)
- Problem-solving ability (0-10 points)
- How do they describe handling difficult situations with children or in previous roles?
- Physical and mental wellness (0-5 points)
- Any health concerns disclosed? Realistic expectations about the role?
Total possible: 100 points. Adjust weights based on your priorities—if language skills matter more, bump that category up.
Score Honestly, Not Optimistically
When evaluating each candidate, score based on evidence, not potential. A 19-year-old with only babysitting experience shouldn't score the same as someone with two years as a live-in au pair, even if the younger candidate seems eager. Reference calls are your best tool here: ask previous host families about actual performance, not just general impressions.
Look for red flags:
- Vague answers about why they left previous positions
- Inconsistencies between resume and interview
- Unwillingness to discuss payment expectations or house rules upfront
- Poor communication during the application process itself
Calculate Weighted Scores
Once you've scored all candidates, multiply each category score by its weight. If childcare experience is worth 25 points and a candidate scores 18, that's 18 points in that category. Add all weighted scores for a final total per candidate.
This removes subjective impressions: the candidate who felt "warm" in an interview might actually score lower than the one who impressed you less personally but has stronger credentials.
The Final Conversation
Before you hire, conduct a final call or video interview with your top 1-2 candidates. This isn't about re-scoring—it's about gut-checking that your matrix assessment reflects reality. Ask questions directly about scenarios specific to your family: "If one child doesn't want to go to bed and the other is hungry, how would you handle it?"
Trust the matrix, but don't ignore serious doubts that surface here.
Making the Offer
Once you've decided, move quickly. Strong candidates get multiple offers. When you contact your choice, provide a written offer letter that covers wages, start date, working hours, time off, and house rules. This prevents miscommunication later.
Platforms like Mercoly help you compare and find trusted au pair placement providers in one place, so you can access vetted candidates and make confident hiring decisions faster.
Frequently Asked Questions
Q: How many reference checks should I do per candidate? Call at least two previous host families; a third is ideal if the candidate has longer work history. Ask specific questions about challenges and day-to-day performance rather than general impressions.
Q: What's a typical salary range for an au pair? In the US, wages typically range $195–$215 per week; in the UK, expect £80–120 per week. Rates vary by location, experience, and local regulations—always research your country's au pair requirements.
Q: How long should my decision process take? Plan 2–3 weeks from application deadline to offer. This allows time for phone interviews, reference calls, and sleep on your decision without losing candidates to other host families.
