2026
Almost there . . .
At MummyNanny, our mission is to empower Mummies with the knowledge to make informed decisions while also celebrating the hardworking Nannies who consistently deliver exceptional care. To achieve this, we've developed a transparent and balanced ranking system based on two main criteria:
|
1.
|
Truncated Total Evaluation Score |
|
After each job, Mummies are invited to evaluate their Nanny's service across three areas:
Cooking (5 points max)
Baby Care (5 points max)
Mummy Care (5 points max) This gives a maximum of 15 points per job. To ensure fairness and reflect consistent quality, we calculate a Truncated Total Evaluation Score by summing the Nanny's highest evaluation scores within the evaluation period. |

Average Evaluation Score:
13.4
A Nanny who receives scores of 15, 13, 15, 13, 11, 13, 15, and 12 across 8 jobs within the evaluation period will have a Truncated Total Evaluation Score of 84 (if we take the 6 highest scores). |

|
This approach:
Rewards Nannies who stay active throughout the year
Encourages consistent, high-quality service
Reflects input from multiple Mummies (not just one or two)
Gives room for improvement, without punishing early learning or one-off mistakes We intentionally moved away from using Average Scores only, as Mummies expressed difficulty trusting rankings based on a small number of high-rated jobs. This method helps build confidence through demonstrated, ongoing excellence. |

Job Portfolio Counting RulesTo maintain ranking integrity and ensure evaluations reflect breadth of performance across different families, we apply the following rule: "One job portfolio per unique family per ranking cycle" If a Nanny is hired multiple times by the same family within a single ranking cycle, thereby creating multiple job portfolios, only the job portfolio with the highest evaluation score is considered in the rankings. This ensures that ranking points accurately represent verified performance across diverse family contexts, rather than repeated engagements with the same family. However, if a Nanny is rehired by the same family in a subsequent ranking cycle, this constitutes a new job portfolio, as it demonstrates sustained trust and satisfaction over time. Annual ranking cycle example: If Nanny A works for Family B in January 2024 and is rehired by the same family in June 2024, only the higher-scoring portfolio between the two engagements will be counted in the 2025 rankings. If Family B rehires Nanny A again in 2025 (for the same baby or a different child), this would count as a separate job portfolio in the 2026 rankings, as the jobs occurred in different calendar years. Note: Job portfolios are included in rankings based on the year the job ended. For annual global rankings, jobs completed in 2024 are considered in the 2025 rankings, jobs completed in 2025 are considered in the 2026 rankings, and so on. For country rankings, the same principle applies across the 4-year evaluation window. |

Profile Strength |
|
We also evaluate the completeness and credibility of a Nanny's profile. A strong profile helps Mummies better understand who the Nanny is and what they can expect. We assess the following elements:
Personal introduction and languages spoken
Personal photos for connection and trust
Annual job statistics
Preferred and past job locations
Sleeping preferences
Types of food prepared
Job packages offered
Payment structure
Best qualities
Unique username for easy recognition Each completed item earns 1 point. These are normalized to a maximum of 15 points for Profile Strength. A high Profile Strength score indicates an informative, trustworthy, and up-to-date profile, making it easier for Mummies to compare options and choose with confidence. |
TESTING AND FEEDBACK
We tested several ranking approaches, including one based solely on Average Evaluation Score. This would highlight Nannies who only took on a few jobs but earned perfect ratings. For example, a Nanny who completed just one job lasting several months and received a perfect 15-point evaluation would appear at the top of the rankings under this method.
While it sounds fair, this method had drawbacks:
Mummies found it misleading and did not reflect a Nanny's overall performance—how can you trust a profile with only one or a few high-scoring evaluations?
Nannies felt it unfairly favored those who completed fewer jobs per year, rather than those who served many families consistently and reliably.
Based on this feedback, we refined our system to recognize both performance and professionalism over time. We also considered job duration. While some Nannies may take longer jobs, the average confinement job on our platform lasts about 28 days. Since most Nannies can take up to 6–8 jobs per year (with a 14-day break between each), our truncation method (top 6 scores) provides a fair reflection of their work.
FINAL METRICS
Our ranking system is based on:
Truncated Total Evaluation Score. Reflects performance across multiple jobs and feedback from different Mummies.
Profile Strength. Reflects transparency, credibility, and effort put into presenting a trustworthy profile.
The global rankings consider the Nanny's 6 highest evaluation scores within the past calendar year. For the country rankings, we consider the Nanny's 24 highest evaluation scores within the last 4 years for jobs within the specified country.
This dual-metric approach strikes a fair balance—giving Mummies the information they need, and giving Nannies credit for consistent, reliable, and quality care. We are always evolving, and this system will continue to improve with feedback from our community.
