Learning
Breadth of knowledge, balance of studies, and active participation.
CAISL educates students from age 3 through Grade 12, the final year of High School. As an American international school, we combine best practices from American education with the rich perspectives of a multicultural community representing over 60 nationalities. Learning extends beyond the classroom through regular visits to historical and natural sites in the Lisbon area.
The American education system offers students a broad and balanced academic experience from the early years through high school. At CAISL, this means students engage with all major areas of knowledge throughout their educational journey, allowing them to explore interests, develop strengths, and build a strong academic foundation.
All students graduate from CAISL with an American High School Diploma. In Grades 11 and 12, students may also choose to pursue the International Baccalaureate Diploma Program (IB DP). Both diplomas are widely recognized by universities around the world.
While knowledge can be gained through books and exams, true education requires applying learning to real-world challenges and working collaboratively with others. At CAISL, our curriculum reflects this belief by offering a rich and balanced program of academics, arts, and athletics that encourages students to strive for both individual growth and collective excellence.
