Aon Best Employers–About the Certification

About the Aon Best Employers Certification

Aon Best Employers certification recognizes leading employers that are reinventing the workplace for now and the future. Looking at the health of organizations from the inside, we certify extraordinary employers using the most objective measure possible – employee opinion.

Creating Amazing Employee Experience

Our research shows that extraordinary employers are creating an amazing employee experience by excelling on four measurable “people factors”. Aon Best Employers surpass other organizations on these critical factors and create sustainable competitive advantage.


Employees speak positively about their employer, intend to stay and are motivated to exert extra effort at work.


Employees see that the organization is highly adaptive, innovative, inclusive and responsive to the changing needs of its customers.

Engaging  Leadership

Leaders are deeply connected with employees to drive engagement, communicate a clear vision and exert strong personal values.

Talent Focus

The organization is focusing on attracting and retaining great talent and accelerating people's potential to the extraordinary.

Being certified as an Aon Best Employer means you created a workplace where people feel heard, highly connected and empowered to do their best, every day.

How to Get Certified?

Conduct an Employee Engagement Survey

The methodology used to determine an organization's qualification as an Aon Best Employer is an integral part of Aon's employee engagement methodology. You will work with Aon culture and engagement survey experts to conduct an employee engagement survey that works best for you:

Rapid Engagement*

Cost-effective, ready to use online survey


Tailored Engagement*

Custom survey allowing additional flexibility for survey design and timing

* Please contact one of our consultants if you want to get more details about these two options.

Aon will analyze your results by country/market, region or globally

Using survey data collected from employees, the four indices mentioned above are calculated for each organization at country level and then compared to relevant Aon thresholds. Aon sets the top quartile thresholds for the four indices annually, using data from its global employee research database.

To be recognized as an Aon Best Employer, your organization must be top quartile for engagement as well as top quartile for 2 out of 3 of the other indices (1)
