It has two units, a pre- and primary school division, covering from maternelle (preschool and infant classes) and elémentaire (junior classes), in a building on Foxrock Avenue in Foxrock, and a secondary school, comprising collège (junior cycle secondary) and lycée (senior cycle secondary), at the Eurocampus in Clonskeagh,[5] shared with St. Kilian's Deutsche Schule, to which they moved in 2001.

The initial mission of the Lycée français international Samuel Beckett is to provide schooling for French-speaking students living permanently or temporarily in Ireland.

Today, the school's bilingual educational project attracts students of many nationalities.

Another sign of the school's European openness is the special program of study visits set up in recent years.

They stay with host families and prepare for English language certification (usually Cambridge) while continuing their studies.
