High School

Academically, our High School students are critical thinkers and writers who are motivated to succeed. Students regularly demonstrate persistence, an ability to learn from their mistakes and have a global mindset that embraces inclusion and diversity. 

About The High School Curriculum

The academic program is a challenging and engaging curriculum designed to prepare students for entry to the top universities and colleges in the world. Students take courses in Social Studies, English, Spanish, Mathematics, Science, Physical Education and the Arts to foster a love of learning in a broad range of subjects. Students also take the PSAT Exam in grades 9, 10, and 11 which requires the same testing strategies needed to succeed in the SAT, which is the external exam that we prepare our students to take. 

As well, we offer the Costa Rican Bachillerato courses which prepare students for the MEP exams in their senior year and thus, qualify for university studies in Costa Rica.

Advanced Placement (AP) Courses

We also offer 20 Advanced Placement courses beginning in the Sophomore Year with AP World History. Our AP courses are the most rigorous courses offered in the high school and students freely choose, through an application process, to undertake these rigorous courses.

Technology In High School

The academic program is enhanced by our 1:1 laptop program, a model replicated by leading secondary schools worldwide. This program equips our students with the skills for effective communication, research, and individual projects. Our teachers integrate technology into a philosophy of “learn-first, tech-second,” in other words we want technology to be more than an expensive pencil, we want it to enhance the learning experience.

Outside Of The Classroom

Last year we had a record number of students enrolled in our Band and Choir programs. We also have an internationally recognized Model United Nations Club, a community minded National Honors Society, and we compete at AASCA sports events for boys’ and girls’ teams in Basketball, Track & Field, Soccer and Volleyball. Furthermore, students are encouraged to create leadership opportunities that reflect a commitment to contribute meaningfully to build community locally, nationally and globally.

We are very proud of our students and the leadership traits they demonstrate on a daily basis – empathy, self-confidence, integrity, enthusiasm, optimism, authenticity, perseverance, passion, and critical thinking.
