Assumption College (AC)

What Assumption College (AC) does

Assumption College (AC) is a private Catholic boys' secondary school in Bangkok, Thailand, operating under the Saint Gabriel Foundation Thailand — a nonprofit religious foundation managing 18+ educational institutions. Founded in 1877 by French Abbot Father Émile August Colombet and officially established as Collège De L'Assomption on 16 February 1885, the school provides secondary education for students in Mathayom 1-6 (Grades 7-12, ages 12-18) through a portfolio of 7 specialized lower-secondary programs and 11 upper-secondary tracks spanning science, mathematics, engineering, health sciences, digital technology, business administration, art & design, sports, and future skills, with both Thai-language and English-medium instruction.

The school delivers instruction through a Montfortian values-based curriculum integrated with STEAM and project-based learning, supported by proprietary facilities including the DREAMS Maker Space (aerospace, electronics, mechanics, 3D modeling, aviation training, and metaverse studios), the AC Counseling and Wellbeing Center (3 consultation rooms, 2 professional psychologists), the Martin de Tours Library (Dewey Decimal system, self-service borrowing), and computer/robotics laboratories. AC also operates an Assumption College Primary Section established in 1965 at Sathorn, and maintains international academic partnerships with institutions in the UK, China, New Zealand, and France. Performance signals include a World Champion title at the Annual CanSat Competition 2026 (Team DAEDALUS), multiple national Olympiad medals, and a 2026 volleyball championship.

The school generates revenue primarily through tuition and fees for its secondary programs, one-time application fees (1,000 baht per applicant), and donations routed through the alumni-managed Fund for Assumption College. It markets through its website, social channels (Facebook, Instagram, Line@), annual Open House events, and earned media coverage. As a nonprofit foundation-operated institution, AC is not venture-backed or publicly traded, and revenue is not publicly disclosed.

Broad incumbents

• Ruamrudee International School: Established international school in Bangkok offering IB and American curricula. Competes with AC for Bangkok families seeking premium international education, but operates as a co-educational day school with broader curriculum scope.
• NIST International School: Large IB World School in Bangkok with strong STEM and technology programs. Comparable to AC in terms of Bangkok location, premium positioning, and emphasis on preparing students for top international universities.
• Shrewsbury International School Bangkok: Premium British-curriculum international school in Bangkok. Targets the same upper-tier Bangkok family market as AC's English Program, with similar emphasis on Cambridge/IGCSE qualifications and university preparation pathways.
• Harrow International School Bangkok: Premium international school in Bangkok serving affluent Thai and expatriate families. Competes with AC for the same Bangkok premium-family segment but offers co-educational, British boarding-school model at higher tuition levels.

Direct peers

• Saint Gabriel's College: Brother Catholic boys' secondary school in Bangkok under the same Saint Gabriel Foundation Thailand network. Operates with the same Montfortian values-based curriculum and similar governance structure, making it the closest comparable peer to Assumption College.
• Bangkok Christian College: Historic Catholic boys' secondary school in Bangkok founded in 1897. Shares similar student demographic (Thai Christian/boys), private secondary education model, and historic brand positioning in Bangkok's elite private school market.

Emerging players
