Even though their initial training ends at the end of the second year at Ensai, civil servant students from Insee ( The French National Institute for the Study of Statistics and Economics), can still follow, after having one year of work experience, their training to achieve the Statistical Engineering degree at Ensai.

At the end of their two years, these students are certified civil servants within the body of Insee attachés. These civil servant students go on to careers at Insee, in the management of statistics for ministers or in public establishments disposing of a statistical department recognized by the management of Insee. In addition, they participate in the conception and statistical reproduction of their work. Also they manage work and its execution, all while contributing to the analysis and distribution of the results.

Beyond other fields of work centered around statistical engineering and social-economic information systems, the career of an Insee attaché can allow the practice of management, marketing, and communication. The executives of Insee follow a diverse professional path, be it in Paris, other parts of France or abroad.
