Polytechnics represent only 10% of administrators today, against a little over 16% in 2008. This is explained by the low feminization of the school. Conversely, the number of graduates from HEC Paris has been maintained over ten years.
This is one of the side effects of the Copé-Zimmermann law, this 2011 law which imposed quotas for women on boards of directors. Graduates from very large French schools are not as numerous in these high governing bodies of the CAC 40 as in the past. Between 2008 and 2017, the proportion of directors from Polytechnique, ENA, HEC, or ENS rose from 36% to 26%, remarks Michel Ferrary, professor of human resources management at the ‘University of Geneva. In number, these graduates who were 200 in 2008 are now only 149.
