EXAMS AND SYLLABUS
The exams and coefficients are the same for statistical engineering students (civilian) and INSEE civil servant student statisticians.
Except for the interview (oral exam), the examination subjects are based on the programs for the entrance exams for ENS in social sciences (CPGE B/L).
The 4 written exams are taken from the group of inter-ENS social science exams (B/L).
The written compositions in social sciences and mathematics are common to all ENS.
The written exam with the sociology or economics option and the written language exam are specific to ENS Paris Saclay.
Shortlisted (eligible) candidates have two oral exams at ENSAI:
- An interview (30 min.) which aims to evaluate the candidates general knowledge and quality of reflection, as well as the candidates’ motivation to become a statistician (engineer or civil servant). The format and evaluation method can be consulted by clicking on the links above
- A mathematics oral exam (30 min.) which has two parts and tests knowledge from the BL preparatory classes’ curriculum:
- one exercise drawn at random by the candidate, prepared for 30 min., and presented to the jury for 15 min.
- one exercise, without preparation time, on a different topic than the previous one, which allows the jury to evaluate the candidates’ reactivity in real-time, followed by questions from the jury, for a total of 15 min.
Either way, every candidate has a question about probability/statistics, either as the main prepared presentation or as the secondary unprepared activity. Both of these exercises are done on the (white)board and calculators are not allowed.
For all the exams, except the language test, all scores below 5/20 automatically eliminate the candidate.
