In September 1980, Mrs Susan Farrow founded the British School of Madeira in Funchal to nurture the education needs of children of English residents living in Madeira as well as Portuguese students that wished to enrol in this private school, which offered British education

On March 21, 1985, we received a royal visit from the Duke of Edinburgh, husband of Queen Elizabeth II, joined by Princess Alexandra of Kent during their visit at Madeira Island.

The school provided the British curriculum (Scottish version) in conjunction with part of the official Portuguese Programme. It was officially recognized by the Secretaria Regional de Educação of Madeira (SRE), the British Consulate and the Scottish Qualifications Authority (SQA).

Given the sharp increase in interest in international education in Madeira Island, the school felt the need to move to better and larger facilities.

Students leaving British School Madeira could transfer to any Portuguese school through a Certificate of Study Equivalence awarded by SRE and to any English-language school anywhere in the world.

Sharing Foundation starts to implement its mission and acquires British School and changes the name to Madeira Multilingual School. During the academic year, Madeira Multilingual School began the authorization process to become an IB World School.

After three years as a candidate school, we were the second school in the country to achieve accreditation to offer two IB Programmes: (Primary Years Programme (PYP) and Middle Years Programme (MYP).

In the year 2018/2019, the school began a transformation process and started using the new name – International Sharing School. This name was officially implemented in the year 2018/2019.

With this new acquisition, Sharing Foundation started its mission by offering the IB programmes to International families who live in the Lisbon Metropolitan Area.

As an IB candidate world school, ISS started to offer all IB Programmes (PYP, MYP and DP) to students from 3 to 18 years of age, also welcoming students in our Foundation Programme from 4 months-old to 2 years-old. This was an exciting time for our school as we were starting to make our mark on the educational landscape in Lisbon and Portugal.

After two years of candidacy, we finally received the status of becoming an IB World School. During the IB verification meeting, the team recognised our hard work and authorised our Taguspark Campus to offer the Diploma Programme to our local and international community between the ages of 16 and 18.

Oeiras Campus is a fully authorized IB Continuum School and offers three programmes of IB; (PYP) Primary Years Programme, (MYP) Middle Years Programme and (DP) Diploma Programme.

We open a new building fully dedicated to the MYP and DP.

Our school was nominated as one of the 10 Must-Watch International Schools in Europe by the International Advisory Board of the K-12 Digest Magazine, composed of several specialists in the education sector around the world.
