Children from the ages of 3 to 18 attending ISSL enjoy an exceptional education.

The school operates with the internationally recognised[1] and demanding Cambridge IGCSE and A-Level programme of study.

This programme offers a broad choice of curriculum and has a reputation for developing successful students.

[2] ISSL has integrated the teaching of the national language and culture into their curriculum, with a department of dedicated and qualified Portuguese staff specialising in the teaching of their country's language and culture.

This will increase the opportunity for those attending the school to leave it fully bi-lingual.
