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!"

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
