What Concordian International School does
Concordian International School is a private, non-profit international school founded in 2001 by Varnnee Chearavanont Ross, operating from a purpose-built campus on Bangna-Trad Highway in Samut Prakarn, on the eastern fringe of Bangkok, Thailand. The school delivers the full International Baccalaureate continuum — Primary Years Programme (PYP, authorized 2004), Middle Years Programme (MYP, authorized 2007), and Diploma Programme (DP, authorized 2008) — to approximately 1,100 students from Pre-K through Grade 12 under a trilingual instructional model delivered in English, Mandarin Chinese, and Thai. Concordian holds the unique IB authorization to deliver English-Chinese immersion in the primary years, with all three IB programmes taught through core instruction across the three languages rather than as a separate subject. The academic program is delivered by a faculty drawn from 25 countries (more than two-thirds holding master's degrees) on a wireless-enabled campus with 650 CCTV cameras and 24-hour security, and is supported by NACAC- and International ACAC-certified college counselling through the BridgeU platform.
The business model is direct-to-consumer tuition-based: families apply online or in paper form, attend school tours, complete entrance assessments and interviews, and pay recurring annual tuition (pricing not publicly disclosed). The primary customer segment is affluent expatriate and Thai-Chinese families in Bangkok and the eastern residential clusters (Bangna, Bearing, On Nut, Sri Nakarin, Eastern Seaboard), seeking internationally portable education for children aged 2–18. Revenue streams include core tuition and fees plus ancillary programs — the Concordian Summer School, After School Activities (ASA) / Creative Minds Academy (CMAs), and a Residency Boarding Programme — alongside Founder's and Talent scholarships. The school is governed by a Board of Trustees, licensed by the Thai Ministry of Education, quality-assured by ONESQA, and accredited by CIS (reaccredited February 2022) and NEASC.
Concordian's track record anchors its positioning: 17 consecutive graduating classes with a 100% Grade 12 graduation rate, an IB Diploma average of 37 points (Class of 2026) running ~4.7 points above the worldwide average, US$34.4 million in scholarships offered to 41 graduates in the Class of 2026, and admissions at 400+ distinct universities across the US, UK, Canada, China, Hong Kong, Australia, and Thailand since 2010. The school pursues partnerships that extend its value proposition beyond the campus, including a G9 exchange with Keystone Academy in Beijing, a China Scholarship Council relationship, and internship placements at Super Brand Mall Shanghai. No revenue, funding events, or ownership changes are publicly disclosed; the institution is privately held and has not raised external capital.
