Since their early studies in CSi students are taught in two languages: Portuguese and English, following the English National Curriculum modified to cater for each student´s needs. There is a great emphasis on the learning of mathematics and science, these subjects are embedded throughout the curriculum.




Our commitment lies in creating an international culture, we aim to captivate the students interest in other languages and cultures.

The Arts and Sports component is given great importance, the school carefully plans several curricular and extra-curricular activities both in and outside its own facilities.


Given the current scenario of economic and cultural globalization in which we live, learning a second language becomes essential, mainly the English language.

In the CSi, bilingual education provides the socio-cultural education in two languages, English and Portuguese.

It has an appropriate curriculum to encourage the development of cognitive, emotional, physical and social needs of each age group, adapted to the needs of all students. With qualified and trained teachers of bilingual learning, the Colegio Santiago Internacional offers to its educational community the possibility of acquiring a second language and the ability to use it fluently.

The CSi offers a rigorous curriculum taking into consideration the needs of each individual student with differentiated and individualized learning. We use information technology to better differentiate within the lessons.

The CSi believes that both students and professionals that make up the team of the College should take advantage of training and continuous assessment. This defines life as an ongoing process of learning. It is therefore understandable that the teaching and learning are part of a plan of development training for all ages.
