AIT International School (AITIS) sits inside the Asian Institute of Technology (AIT) campus at 58 Moo 9, Km. 42, Paholyothin Highway, Khlong Nueng, in Khlong Luang District. Founded in 1974 to serve AIT staff and postgraduate-student families, it is Pathum Thani's longest-running international school and has been open to the wider public since 2007. All instruction is in English on an American-based curriculum modified to international standards, with Thai language classes offered for both native speakers and newcomers. Annual tuition runs roughly THB 400,700 to 873,800 depending on grade, per the site's own existing Pathum Thani schools guide. AITIS remains small, close-knit and deeply tied to Pathum Thani's international academic and research community.

AITIS suits families relocating specifically for AIT or nearby Thammasat University who want a familiar, American-style curriculum and a small, close-knit school community with more than fifty years of history in the same location. Because the school has historically prioritised places for AIT staff and student families, applicants joining the university or institute directly should apply early. Families wanting a full IB pathway instead should look at KIS International School Reignwood Park; families wanting a lower-cost bilingual route should look at Satit Bilingual School of Rangsit University (SBS Rangsit) or Sarasas Witaed Rangsit.
AITIS is inside the AIT campus at 58 Moo 9, Km. 42, Paholyothin Highway, Khlong Nueng, Khlong Luang. Most families live on or near the AIT campus itself, within walking or short motorbike distance, with easy access to Thammasat University Hospital nearby. Pathum Thani has no rail-transit station within easy reach of this specific campus, so most families drive or use campus transport; confirm current arrangements directly with the school.
