Trinity International School

Trinity International School is located at 30 Sukhumvit Soi 36, Khlong Tan, Khlong Toei, Bangkok 10110. It sits in the Sukhumvit area, a well-connected part of the city, with Thonglor BTS station at the entrance to Soi 36, making it accessible for families using public transport. The neighbourhood is a mix of residential streets and commercial amenities, offering convenience for commuting parents.

The school offers education from Kindergarten (ages 3+) through Grade 12. This covers early years, elementary, middle school, and high school levels, with age-appropriate curricula for each stage.

TRIS is a co-educational day school. It does not provide boarding facilities.

The school provides Learning Support for students who require extra help, with teachers and support staff working with parents to meet individual needs. Students with limited English proficiency can join the ESL program until they are ready to join mainstream classes.

TRIS follows the American (California) curriculum and is accredited by the Western Association of Schools and Colleges (WASC), a U.S.-based body.

The school is affiliated with the Seventh-day Adventist Church and incorporates values education based on Adventist principles.

The school day runs from 07:30 to 15:00, with student arrival between 06:45 and 07:25. Students begin the day in homeroom with the national anthem, attendance, and announcements, and have scheduled breaks and a lunch period during the day.

TRIS operates its own van service for transporting students to and from school.

Trinity follows an American curriculum based on the California Department of Education’s K‑12 standards, with content adapted to support Math and Science through a partnership with UC Berkeley’s GEMS program. From Kindergarten through Grade 12, students follow this American-based program, integrating values education rooted in Seventh‑day Adventist principles. Early grades (K–5) focus on foundational literacy, numeracy, and values such as honesty and respect, while middle and high school include Advanced Placement (AP)‑level coursework in subjects like Calculus, Physics, Chemistry, and more. The curriculum also includes an English as a Second Language (ESL) program to support students not yet fluent in English, including summer school, until they can move into mainstream classrooms. Overall, TRIS provides a structured academic progression from early years to Grade 12 that combines U.S. academic standards with holistic character development and technical enrichment.

While the school states that lessons emphasize collaborative learning, critical thinking, and practical application within its California-aligned curriculum, there is no direct mention of a dedicated “SEL” program, staff, or formal initiative focused explicitly on social and emotional learning.

Trinity offers “Learning Support”, where teachers, learning support staff, and parents collaborate to tailor support for each student’s needs. However, the school does not publicly detail the types of special educational needs it supports or confirm whether it operates as a specialist SEN school.

The school provides English as an Additional Language (EAL) support through its English as a Second Language (ESL) program. This program is designed to help students with limited English proficiency improve their language skills, with smaller class sizes and tailored instruction to support their transition into mainstream classes.

There is no specific information on the school site regarding mental wellbeing programs, dedicated staff like counsellors, or wellbeing-focused initiatives.

The website does not publicly share details about safeguarding policies, child protection measures, or how these are enacted within the school community.
