SISB Schools Marks 25 Years of Educational Excellence
SISB Schools celebrates its 25th anniversary, reflecting on its growth from a small campus in Bangkok to a network of six schools across Thailand, offering a blend of Singaporean and international curricula. The institution highlights its commitment to holistic education and the achievements of its graduates, while introducing a new sister school, Marina Singapore International School, set to open in 2027.

SISB Schools is celebrating its 25th anniversary this year, marking a quarter-century of educational excellence and nurturing future leaders. Founded in 2001 with just 35 students in Bangkok, the school has grown into a network of six campuses across Thailand, offering a blend of Singaporean and international curricula.
## From Humble Beginnings to Educational Leadership
The journey of SISB Schools began with a vision to bring the strengths of Singapore's education system to Thailand. Co-founder and Governing Board Chair Kelvin Koh shared that the school was established by a group of parents who wanted to provide students with a strong foundation in mathematics, science, and languages, including English, Chinese, and Thai.
Over the years, SISB expanded its academic offerings, becoming an official International Primary School Examination (iPSLE) center in 2006. The school later introduced the Cambridge IGCSE and International A/AS Levels, followed by the International Baccalaureate Diploma Programme (IBDP) in 2019. This evolution has given students greater flexibility in shaping their academic paths.
Today, SISB operates six campuses, including four in the Bangkok Metropolitan Region and two in Chiangmai and Rayong. The school's holistic approach to education emphasizes co-curricular activities, helping students discover their strengths and reach their full potential.
## Celebrating Achievements and Future Opportunities
The impact of SISB's educational journey is evident in the achievements of its graduates. The Class of 2026 received over 250 university offers from more than 90 institutions worldwide, showcasing the strong foundation built during their time at SISB. These accomplishments reflect the school's commitment to preparing students for global opportunities.
Looking ahead, SISB is introducing Marina Singapore International School, a new sister school set to open in August 2027. Located within the Supalai Community Living Hub in Rangsit, the school will initially serve students from Nursery 1 to Primary 4, with plans to expand up to Grade 12. This new chapter builds on SISB's 25 years of experience, aiming to make quality education more accessible to future generations.
As SISB celebrates its Silver Jubilee, it invites the community to join in honoring its past while embracing the opportunities of the future.
