For us, diversity is an advantage. It develops and enriches.

We are tolerant toward every nationality, culture, and faith. We welcome children from near and far who seek a warm environment and an enriching multilingual community.

For us, school and family are one whole. Teachers and parents walk together on the path of children’s growth, sharing common values and visions for their development.

That is why the first step in our admissions process is a preliminary meeting with the family. During this conversation, we discuss the student’s individual educational goals and needs, while also understanding the parents’ vision for their child’s future development.

To evaluate the child’s readiness for adaptation and academic preparation, every student attends a mandatory trial day at our school. This gives the child the opportunity to experience the learning process, meet the team, and get to know future classmates. If the child feels calm and accepted, then the first step toward joining our school community has already been made.
