Level 1 modules aim at (1) covering a large area of computer science research, and/or (2) giving a solid background for some theoretical and technical level 2 modules. A module takes place on a semester (resp. half a semester) and approximatively corresponds to 75 hours per student: 50 (resp. 25) hours of lessons and exercices and 25 (resp. 12.5) hours of personal works. It provides 6 (resp. 3) ECTS.

The M1 modules listed below are offered by ENS Paris (timetable) and ENS Paris-Saclay (timetable). They can be located at ENS Paris or ENS Paris-Saclay (Cachan campus). The list below includes a title, a teacher in charge, a university and a link to a description. As for level 2 modules, this list may evolve every year.

Subject to the approval of the Study Director, other courses can be integrated in the M1 study plan, in particular ENS Paris-Saclay L3 courses and MPRI M2 modules (both count as MPRI ECTS) as well as Paris Diderot M1 modules (external ECTS).
