  • First year at ENSAI, a graduate school specialized in Statistics. Discover ENSAI's mission

ENSAI’s mission is to prepare its students for professions involving the collection and analysis of information, especially in the social and economic spheres but also for industry, life sciences, marketing, finance, health, and information systems.

The schooling lasts two years for civil servant statisticians, and three years for statistical engineering students.

Civil servant statisticians and statistical engineering students follow the same classes for the most part, sit the same exams and are marked together. However, in the second semester of the second year, the students choose their classes. Statistical engineering students make their choice on the basis of their intended third-year specialization and civil servant statisticians on the basis of their future career working in National Statistics for INSEE, the French National Institute for Statistics and Economic Studies.

Thanks to partnerships, engineering and civil servant students can obtain, under certain conditions, a licence (L3 level) in Applied Economics with the Paris Dauphine University, or a licence in Mathematics et Rennes 1 University. The cursus leading to the licence in Economics is done during the second year at Ensai.


The first-year core syllabus (in statistics, mathematics, computer science, economics, social sciences, management, and languages) provides an introduction to the basic knowledge and methods of reasoning required to obtain a good general culture in the areas involved. Teaching in the second and third years then builds on this knowledge and these methods, exploring them in greater depth.

For this reason, and given that a fair proportion of these subjects are new to most students, nearly all of the first year is devoted to the core syllabus.

However, since ENSAI’s students arrive via different selection routes, they have differing specific knowledge, and so the school provides teaching in mathematics, probability and statistics to distinguish those having specialized in mathematics on the one hand, and two different levels of economics courses that progress at different rates depending upon the students’ background (in mathematics, economics, Data Processing and Statistical Computing, or civil servant statisticians).

Internships for statistical engineering students

Students are required to go on three internships during their studies in order to be awarded an ENSAI statistical engineering diploma. They are also required to spend a minimum of four weeks abroad, either as part of these
internships, as a student in a foreign institution, or on a linguistic stay abroad.

At the end of their first year, students complete a company discovery internship. This starts in June and lasts for a minimum of four weeks. The aim is to allow students to discover the workplace and its social organisation.

Internships for statisticians in the Civil Service

At the end of their first year, statisticians in the Civil Service are required to go on a 8-week
internship in the National Statistics system to learn about the sort of work carried out. This can be completed in France or abroad within another European national statistics institution.

Tuition Fees

Annual tuition fees (in 2018/2019) are €1850 for statistical engineering students, and free for INSEE civil servant statisticians.

INSEE statisticians receive a brut sum of €1,550 per month throughout their studies. ENSAI awards scholarships to statistical engineering students on the basis of financial need.
