ISB was founded in 1996 in a rented building with a total of just 17 students to meet the needs of the English-speaking community. Within a couple of years, the school had grown in both size and scope. In order to serve an increasingly mobile international community, the curriculum gradually took into consideration the practices and requirements of a number of different systems.
In 2001 the School became the first CIE Exam centre of Romania in order to run IGCSE examinations. The step of becoming a CIE exam centre and the school offering an IGCSE and AS/A level programme has further influenced the multicultural outlook of teachers and students.
Despite separating the Primary School to a different campus in 2003, rapid expansion saw enrolment grow to around 350 students by 2004. This encouraged the school to seek new premises, so a purpose-built campus opened in 2008 in a green area in the eastern part of Bucharest. Ever since, ISB has offered on these premises a state-of-the-art learning environment, on-site sports facilities and a conference hall as well as a cafeteria.
Our School has been fully accredited by CIS (Council of International Schools) since August 2012. ISB is an IB World School authorized to offer the Diploma Programme from September 2017 onwards. Due to the support of an exceptionally close community, the future of ISB promises to be an exciting one.
