[2] The International School of Zanzibar was founded by parents from foreign countries as a play area for their children.

It is a community school catering to both local and foreign families, especially those interested in the Cambridge International curriculum.

In principle the International School of Zanzibar follows the British National Curriculum including the administration of IGCSEs and AS/A-Level exams (the school is an accredited Cambridge Examination Centre that also accepts private candidates[3]).

In 2021 the school graduated its first Year 13 class, and those students have gone on to study in the UK, Switzerland, and Tanzania.

These include Tanzanian (46%), Germany (7%), the United Kingdom (6%), Italian (5%), Egyptian (4%), Finnish (3%), and Spanish (3%).
