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)
