KIS International School

What KIS International School does

KIS International School is a private, family-owned International Baccalaureate World School operating two campuses in Thailand. Founded in 1998 originally as Kesinee International School, the school delivers the complete IB continuum — Early Years Prep (ages 2-3), Primary Years Programme (ages 3-11), Middle Years Programme (ages 11-16), Diploma Programme (ages 16-19), and Career-related Programme (ages 16-19) — to a community exceeding 1,000 students from over 50 nationalities. The Bangkok campus has served the international school market since 1998 with roughly 800 students, while the Reignwood Park campus, opened in August 2024 as a 60-acre purpose-built facility in Pathum Thani, added day and boarding capacity for students aged 9-18 and introduced the only full IB boarding programme in Southeast Asia.

The school's core "technology" is the standardized IB curriculum framework itself, delivered through a 1:8 student-teacher ratio using international faculty and supplemented by third-party digital tools including Seesaw for parent-facing learning portfolios and the MAP adaptive assessment for grades 3 and above. KIS differentiates through implementation quality, an extensive dual-enrollment partnership network (SCAD, Embry-Riddle, ASU, Les Roches, Berklee, SUMAS, The Food School, KMUTT), and enrichment programs including a Golf Academy (CH3 partnership), Week Without Walls experiential learning, Duke of Edinburgh's Award, and ECAs. Accreditations span IB, CIS, ECIS, ISAT, ONESQA, College Board, and UCAS, and the Reignwood Park campus earned LEED Gold certification in November 2025.

KIS generates revenue almost exclusively from recurring tuition and fees across day and boarding programs, with pricing not publicly disclosed and quoted through the admissions office. The go-to-market is direct-to-consumer: rolling year-round admissions managed by a dedicated team of Senior Admissions Managers, Admissions Managers, an Agent Manager, and admissions officers/executives at both campuses, with campus tours and Early Years Open Houses as the primary conversion mechanism. The school also runs fee-generating KIS Camps and the affiliated KISPIRE Family Inspiration Center, but the IB tuition stream is the clear revenue anchor. University placement outcomes (191 offers across 21 countries, $26M+ in scholarships, average IB score of 35 versus a global average of 30 in the Class of 2025) serve as the principal demand-generation asset.
