Mission

AOI is a Thailand-based education group inspired by Dr Arthit Ourairat’s belief in education that serves society.

Across a family of globally focussed international schools, AOI inspires students to reach high standards of academic excellence and holistic wellbeing. Our learners are future-focussed, innovative, and grounded in integrity and compassion as they prepare to become leaders for tomorrow.

Founder’s legacy

I believe that people are the key to developing strong nations, and that education plays a crucial role in fostering a prosperous society.

That belief gives AOI its centre: education that serves society, carried forward through schools that prepare internationally minded students in Thailand to contribute meaningfully to the world around them.

From Rangsit College and Rangsit University to BISP and the SBS schools, the legacy is institutional as well as personal: a conviction that schools can shape the people who shape society.
