CIENS offers all PSL students, regardless of their major, two PSL Weeks per year.

Each PSL Week (list available on the PSL website) features intensive courses spread over five days, totaling approximately 30 hours of instruction. The courses are taught by both academics (primarily CIENS faculty members) and practitioners in strategic affairs. The first-semester PSL-Week (late November) is dedicated to emerging areas of conflict (cyber, outer space, information warfare). The PSL-Week in the second semester (early March) is dedicated to major nuclear issues.

Alongside the coursework, students apply their new knowledge in a “Serious Game” (crisis simulation).
