Our Mission


The mission of The Renaissance International School is to provide students with an international center of learning and culture that is open, supportive, and multidisciplinary, where children can develop and achieve their highest potential.


We are committed to offer students an education based on the research and resulting philosophies of Maria Montessori and Zoltán Kodály. We are a three-language immersion Montessori program with a diverse faculty and student community. 

Why do so many families choose Montessori?

Lessons are designed and given to each child when they are most ready to learn.

Social, emotional, and physical development is emphasized along with academic skills.

Freedom to move and choose activities fosters independence and self-confidence.

Current neurology and human development research consistently backs Montessori.

“We selected TRIS as our school because of its Montessori approach to learning and development. Having spent their entire matriculation in the Montessori setting, we recognized the value of continuing in this method of learning. My children immediately demonstrated a sense of familiarity and confidence in the environment. As students, they both thrived in learning how to take responsibility and learn to be engaged in their own growth process."

“Our daughter is entering 6th grade… wow!!! She plays flute and piano (begun at TRIS) and is keeping up with her French. She plays basketball and socially is thriving with friends and many adventures. We met up with another TRIS family in Ireland this Spring - the comfort and bonds of TRIS friendships live on. Sending lots of love and good wishes to the TRIS family. You know how much I miss you!"

Peace and Montessori Education
By Renee Hites March 4, 2026
In a world that often feels rushed and fragmented, Montessori education offers something rare: a place where children are truly seen. It is an approach built not just on academic achievement, but on the belief that education, real education, has the power to change the world. Maria Montessori developed her method in the early twentieth century, but her deepest conviction was not about reading or mathematics. It was about peace. She believed that if we want a more peaceful world, we must begin with the child. " Establishing lasting peace ," she wrote, " is the work of education ." In a Montessori classroom, peace is not simply a topic that is taught. It is something that is lived. Children of different ages work alongside one another, learning to collaborate rather than compete. They develop independence, not because they are left alone, but because they are trusted. They are given real work that matters, real choices that shape their day, and real consequences that teach them to think carefully about their actions. This freedom, however, is always balanced with responsibility. Children learn to care for their environment, to resolve conflicts with words, and to consider the needs of others as naturally as they consider their own. Grace and courtesy are woven into the fabric of every day, not as rules imposed from the outside, but as habits grown from the inside. Montessori also understood something profound about the child's relationship with the world itself. Through Cosmic Education, the sweeping story of the universe, the Earth, life, and human civilization, children come to see themselves not as isolated individuals, but as participants in something vast and interconnected. They learn that every living thing depends on every other, that the air we breathe was shaped by ancient organisms, that the words we speak carry the fingerprints of countless civilizations. This perspective cultivates humility, wonder, and a deep sense of responsibility toward the world and toward one another. What you will see today in our classrooms is a reflection of that vision. The quiet concentration, the purposeful movement, the children helping one another: these are not accidents. They are the fruits of an environment carefully prepared to bring out the best in each child. Montessori education does not promise to solve the world's problems. But it does promise to raise children who are capable of empathy, who know how to listen, who find meaning in contributing to something greater than themselves. And in that promise lies something quietly extraordinary: the possibility that the children in these rooms might one day help build the more peaceful world we are all hoping for.
Afternoon In Elementary
By Wellington Pontes Filho February 12, 2026
An Afternoon in Elementary is a wonderful opportunity for preschool and Kindergarten families to experience the Montessori Elementary environment and learn more about this exciting next step in their child's journey. This event is designed to help parents understand how Montessori Elementary builds naturally upon the foundation established in the primary years. In Elementary, children continue to grow as independent, confident learners while engaging with big ideas in math, language, science, and cultural studies through hands-on materials, collaborative work, and guided exploration. This year, our An afternoon in Elementary event was again a great success, bringing together children and their parents for a variety of engaging activities. These activities were led by Elementary students, with the support and supervision of Elementary staff and parent volunteers. The participants enjoyed the wonderful freshly baked French bread, explored the wonders of magnetism through experiments, and discovered a love of botany at the gardening and pot-decorating stations. There was great excitement during the math relay and while sewing geometric shapes. In Elementary, we also care for the health of both mind and body, which was reflected in the sports relay station. Creativity shone through our arts and crafts and face-painting stations. It was gratifying to see our Elementary students confidently engage with the younger students with empathy and warmth, guiding them through each activity and sharing their enthusiasm throughout the event. Elementary parent ambassadors were essential to the event's success. They warmly welcomed Primary families, shared information about our Elementary Montessori program, answered questions, and guided children between activity stations. Their support of the Elementary teachers helped create a smooth, welcoming, and engaging experience for all. We know that transitioning to Elementary can bring questions about readiness, independence, and academic expectations. An Afternoon in Elementary offers a space to see how children are supported socially, emotionally, and academically, and how the Elementary environment nurtures curiosity, critical thinking, and a love of learning. We want to extend a sincere thank you to our community for participating in the Afternoon in Elementary event . Their curiosity, enthusiasm, and joy made the event truly special. Warmly, Wellington Pontes-Filho Elementary Program Director
