Who We Are

Our Story

Our language school has been teaching French as a foreign language (FLE) since 1979. We offer a wide range of French training to companies and individuals. Whether for FLE training or to learn beginner French, the Ardevaz SLS offers a tailor-made formula.

Our goal is to offer our students an ideal environment to learn French in the best conditions. Our reputation for excellence has been forged over time thanks to the quality of our French courses and also to a team of teachers who know how to provide personalized attention to the needs and difficulties of each student. Many of our students extend their French courses in our school.
