Because trust is built over time

Read the testimonials of parents who have chosen our school to support their child's development and success.

Enrolling Alyssa in your Montessori school was one of the best decisions of my life. During her three years at collège and lycée, I saw her blossom, gain self-confidence and develop a joy of learning that brightens up her everyday life. Today, she is doing brilliantly in her final year, with an academic level worthy of the best schools, but above all with deep human values: respect, autonomy and sharing.

Alyssa's mum
Secondary school student - November 2025

We particularly appreciated the fact that he was able to regain confidence in his abilities surrounded by caring but demanding people. It wasn't easy for us to choose an independent school. But we quickly became convinced that it was the right choice. Today, we have a son who is happy to have achieved his goal and to see his future as an adventure to be lived rather than a burden.

Pupils in their second to final year of secondary school - June 2021

Our son started at the Montessori School in Bailly at the age of 2 and a half. Here he is at the age of 18, back at the Athena Montessori International High School in Bailly, well in his head as a young adult, confirmed in his worth and in tune with his attentive teachers. For everyone, schooling should be a pleasant experience that builds both self-confidence and learning. Thank you to the whole team who support the adults of tomorrow.
