Assumption College

What Assumption College does

Assumption College (โรงเรียนอัสสัมชัญ) is a private Catholic K-12 institution headquartered at 26 Soi Charoenkrung 40, Bangrak, Bangkok, Thailand. Founded in 1885 by the De La Salle Brothers (now the Gabrielite Brothers) and operating under the St. Gabriel Foundation network, it provides education from primary through secondary levels via the standard Thai national curriculum and a separate English Program (EP). Specialized academic tracks include Digital and Technology, Science-Mathematics, and Business Administration, supported by a Robotics Lab, an iMac Studio Lab, a VR learning program, an AC Smart Farm, and a CanSat/small-satellite engineering program that produced Team DAEDALUS, the World Champion at the Annual CanSat Competition 2026. International credentials are offered through Cambridge, IELTS, and HSK certifications, and the AC PATHWAY program provides higher-education advisory services.

The core technology stack combines Catholic Lasallian pedagogy with consumer-grade educational hardware (Apple iMac, robotics kits, VR) and a proprietary school information management system called SWIS Plus (SWIS PLUS). The business model is subscription/recurring tuition and fees paid by enrolled Bangkok families, with no publicly disclosed pricing and no third-party distribution. Go-to-market is event-driven, anchored by an annual Open House, the school's website, Facebook (AssumptionCollege1885), Instagram (Assumption_style), and a Line Official Account, supplemented by earned media coverage of student achievements.

Customer segments are Bangkok-based families seeking primary and secondary Catholic education, with the Parents and Teachers Association serving as a governance and engagement layer. Revenue and enrollment figures are not publicly disclosed, and the institution operates a single campus with affiliated entities (Assumption College Primary Department, English Program, Assumption Institute of Technology and Space, and the alumni association) forming a vertically integrated educational ecosystem.
