Pre-course Meeting: A pre-course meeting will take place on Monday, September 7, 2020 at 9.30am, Amphi B. Attendance to this meeting is mandatory for all students. The general organization of the year and a description of the courses will be provided. Courses start on Monday, September 7, at 1:30pm.

Training Period: A mandatory full-time training period takes place from Monday, January 25 up to Friday, June 25. An information session about topics and locations for the training period will be organized in September. Basically, the goal is to research in a laboratory (anywhere on earth), write a report and make an oral presentation in the end. Training periods will be defended on June 28 and 29, 2021.

Schedule: Courses start on September 7 at 1:30pm. Autumn holidays are October 24-November 1. Winter holidays are December 26-January 3. Exams will be held at the end of each wave (for those courses with a final). Again, the detailed weekly schedule will be available on the Inria pad mentioned above. This pad will be updated on a regular basis, check it often.

Rules of the Game: To obtain their degree, CS Master students must complete 60 credits including the internship (30 credits) and four courses (5 credits each) in the above list of CR1 to CR19. To summarize, there are 50 mandatory credits out of 60 and 10 remaining credits that can be picked elsewhere. While a typical choice by many students is 6 CR courses and the internship, the extra courses for the 10 remaining credits can be chosen in other masters,  e.g.:
– CS courses in the M2 offered by Univ. Lyon 1
– courses from other ENS departments, often Mathematics ( or Complex Systems (

The diploma delivered by ENS Lyon is M2 Informatique Fondamentale, and computer science must remain at the heart of the curriculum. In particular, the training period must be oriented towards research in core computer science (possibly applied to other disciplines).

Formal Validation: To meet the quality requirements of our program, all course choices must be approved by the academic tutor and the head of the Master 2 program. Administrative registration to chosen courses is mandatory and takes place in late September, after a trial period.

Course validation: At the end of each course, there is an evaluation based upon a research presentation, or a written exam, or both. Many professors also give exercises during the span of the course. The research presentation consists of reviewing and synthesizing a research paper, and usually involves writing  a short report in addition to the oral presentation. Research presentations are time-consuming, hence it is expected that students have a balanced set of courses per each wave. Indeed, the main motivation for the waves is to help students organize their schedules and avoid having 6 research presentations to defend on the same week; instead, having 3 presentations in the first wave and 3 in the second wave is much more likely to succeed!
