Founded in 1992, The Renaissance International School (TRIS) is an independent, non-sectarian Montessori school. Our full-day, year-round program provides individualized education in mixed-age classrooms for toddlers through middle school.
TRIS’s passionate and dedicated educators deliver an exceptional education, guiding students to become compassionate, confident, and creative global citizens prepared to excel in high school, college, and beyond.
TRIS’s Montessori program combines a rigorous academic foundation with music, fine arts, and immersive French, Spanish, and English instruction by native speakers. All students, regardless of background, thrive in our language immersion. Preschoolers participate in bilingual immersion (English/Spanish or English/French), progressing to trilingual immersion (English/Spanish/French) in elementary and middle school. This approach enables students to confidently understand, speak, read, and write in all three languages.
The TRIS program empowers children to think critically, explore deeply, and apply knowledge meaningfully. By adapting to each student’s learning pace and strengths, our educators foster confidence, independence, and a lifelong love of learning—preparing children for success in school and beyond.
TRIS classrooms are purposefully designed to inspire independence, curiosity, and creativity. Personalized curricula encourage students to explore deeply and develop a lasting passion for discovery.
We are truly honored by the trust our community places in us. Thanks to this support, TRIS was voted Best Montessori School in the East Bay in the 2025 Bay Area Parent “Best Of” Awards.
