High School

Moving confidently towards a bright future

High School (Grades 9 through 12) marks the end of students’ school journey. These are years of personal and academical growth, as students keep being challenged in their classes, but also start making plans for their future studies.

As an American School, CAISL offers all its graduating students the American High School Diploma, recognizing not only their academic achievements, but also their qualities as young citizens.

In Grades 11 and 12, CAISL also offers students the possibility to pursue the International Baccalaureate (IB) Diploma, together with the High School Diploma. About 80% of our students choose to do both, challenging themselves with high level classes and external assessments.

With both diplomas, CAISL students enter Universities worldwide, most of them going to the US or the UK or staying in Portugal.
 These all-important decisions are closely supported by our college counselors, who provide students and families guidance through the complex array of post-secondary education options available.

High Schoolers also participate in exciting programs such as Model United Nations, the National Honor Society and the Tri M Musical Honor Society, along with many other exciting opportunities in community service, arts and athletics.
By the end of Grade 12, students graduate confident and positive young adults, and learners for life.

Every day is a promising one in High School.
