**Why a ranking score?**

The ranking score highlights the companies that have the best performance on the HappyIndex®Trainees survey.

But this performance must be reliable and representative, so the participation rate in the survey is strongly taken into account.

**How is the HappyIndex®Trainees ranking calculated?**

Each trainee can spontaneously answer the HappyIndex®Trainees survey on ChooseMyCompany or on the occasion of a survey solicited by his employer.

This survey containing 18 questions allows to calculate 2 values:

- The average of the 18 questions, which is a grade / 5 and which is called "the survey's score"
- A recommendation rate, which is a % of students who answered "agree" or "strongly agree" to the question "I recommend my company to a friend to do an internship there"
- The participation rate in the survey is also calculated as follows: number of respondents* / headcount**

**The ranking score**is equal to the "survey's score" multiplied by 2, then weighted by participation rate and recommendation rate:

- If the participation rate is greater than or equal to 50%, then the coefficient is 1. As soon as this rate decreases, then the coefficient decreases and degrades the survey's score.
- If the recommendation rate is greater than or equal to 75%, then the coefficient is 1. As soon as this rate decreases, then the coefficient decreases and degrades the survey's score.
- The formula is
*2 × HappyIndex × participation rate × recommandation rate*

* About the number of respondents

If the survey is conducted in a solicited way by the employer, the respondents are those who took part in the survey proposed by the employer, open between 01/10 and 30/09

If the survey is conducted spontaneously, the respondents are those who spontaneously gave their opinion on ChooseMyCompany

** About headcount

If the ranking is France, then it is the number of trainees of more than 3 months welcomed each year in France between 01/10 and 30/09

This number is published on the company's page and can be modified freely by the employer directly in his back office (ask us here)
