Welcome to Trinity International School, home of the TRIS Lions!

Thank you for visiting our school’s website. We hope you find it informative and we welcome you to visit us and experience the vibrant and nurturing atmosphere on our campus for yourself.

Founded in 2003, TRIS is a K-12, Seventh-Day Adventist international school in the heart of Bangkok.  Our curriculum is American and based on the California Common Core State Standards and offers Advanced Placement (AP) courses. We are proud to be accredited by WASC, ONESQA, and the Ministry of Education of Thailand.

As a school, we are committed to providing a high-quality and affordable Christian education to our diverse community of students.  Here at Trinity, we appreciate our diversity.  Our students learn Adventist values while respecting all faiths.  Our varied abilities, belief systems, multicultural heritage, and economic backgrounds allow our students to better understand how to function with dignity and respect in an increasingly global society.   

Trinity is a vibrant place to learn and grow.  Our community is welcoming. Our teachers are dedicated and nurturing.  Our students are kind, compassionate, and respectful.  I hope after browsing our website, you and your family will consider joining our community.

Sincerely,

“Ms. Jannet”
