The International British Academy(IBA) was founded in 2001, with just 3 classrooms and 35 students at Km. 30 Gen. Aguinaldo Highway, Dasmariñas, Cavite. The school’s population quickly increased to 156, just 3.5 years after it started its operation and outgrew the Dasmariñas site. IBA moved to a new and bigger facility in Imus, Cavite in April 2005. As of school year 2015-2016, its population has grown to 424 students representing 34 different nationalities.

Three years after its registration with the Department of Education, IBA received its recognition as an NKP, Primary and Secondary school in Cavite.

IBA was registered with the Department for Education and Skills(DfES) of the United Kingdom(UK) in 2002 and was given the DfES No. 703/6439.

From October 2003-2007, International British Academy was registered at the University of Cambridge Center for International Examinations(CIE) as one of its Cambridge International Centers outside of the United Kingdom . CIE is a part of the University of Cambridge Local Examinations Syndicate (UCLES), a department of the prestigious university. This registration allowed IBA to accept examinees for the different qualifications offered by CIE.

Although no longer registered as an Examination Center for CIE, IBA continues to follow the University of Cambridge‘s IGCSE syllabi for many of its core courses in Year 10 and 11 since IGCSE is recognized worldwide as a reliable record of attainment which counts toward entry to universities and colleges around the world, including all British universities. IGCSE was introduced by the University of Cambridge International Examinations in 1988 as an international version of the UK GCSE, therefore, O Level grades are directly equivalent to the UK GCSE and the IGCSE grades; i.e. an A at O Level is equivalent to an A at GCSE and an A at IGCSE. Students graduating from IBA are still able to transition comfortably into the A level in the United Kingdom.
