American International School of Bucharest

What American International School of Bucharest does

The American International School of Bucharest (AISB) is a not-for-profit NGO operating an English-language international school on a 10-hectare purpose-built campus at 196 Pipera Boulevard, Voluntari (northern Bucharest), Romania. Founded in 1962 as the American School of Bucharest with six students and two teachers, AISB has grown to 850+ students from 60+ nationalities and 280+ faculty and staff from 23 countries, offering a continuous educational pathway from age 2 (EC2) through Grade 12. The school is authorized as an IB World School across all three programs (PYP for Early Learning through Grade 5, MYP for Grades 6-10, Diploma Programme for Grades 11-12) and is a founding member of the 28-school Global Impact Diploma network, which offers an alternative Grades 11-12 graduation pathway featuring a semester-long internship and culminating Impact Project.

The school's academic model combines the IB framework with a Reggio Emilia-inspired Early Learning Center (opened 2017), specialist teaching in art, music, PE, digital literacy, and languages (including EAL and mother-tongue programs in 30+ languages), and a multi-tiered system of learning and wellbeing support. Co-curricular offerings exceed 70 activities across athletics, performing arts, robotics (FLL/VEX), Model UN, and student journalism. Recent graduates have been accepted at Dartmouth, UCL, Edinburgh, King's College London, Warwick, Bocconi, Purdue, UBC, University of Amsterdam, and Leiden; AISB reports a 100% IB Diploma pass rate in 2025 with an average score of 34 against a world average of 30.

Revenue is generated almost entirely through recurring annual tuition (€7,810 for EC2 half-day to €28,050 for Grades 9-12), supplemented by a €1,000 annual building fee, one-time application (€250) and registration fees (€800-€3,500), and a competitive scholarship program funded through an annual Gala and Friends of AISB donors. The school holds dual international accreditation (NEASC and IBO), College Board testing authorization, KSCPC Safe School certification, and memberships in CEESA, CASE, ISTA, ISCA, and the International Women's Association. Governance is provided by a nine-member Board of Trustees drawn from current and former parents, with the Board Chair appointed by the US Ambassador; day-to-day operations are led by School Director Rachel Caldwell and a leadership team spanning academics, admissions, finance, technology, athletics, and people and culture. As an NGO, surplus is reinvested into campus, programs, and scholarships rather than distributed.
