Located in privileged locations across Portugal - Cascais, Estoril, Lisbon, and Sintra - Prime School International stands out as a prominent member of the extensive global educational network of Cambridge International, present in over 160 countries. Our schools in Portugal have been globally recognized over the years, not only as centers of internationally renowned education but also as hubs of global connection and innovation. From ages 3 to 18, students have the option to pursue two paths: the Cambridge Curriculum, taught exclusively in English, or a bilingual approach, which values the Portuguese language.

Upon reaching the 9th year (14 years old), students face a crucial decision. They can either continue on the prestigious Cambridge pathway or opt for the Prime Technical Route 2 and 3, which emphasizes practical and technical education, with various options such as sports and hospitality being the most chosen. At Prime School International, education goes beyond traditional teaching. Both our Cambridge Curriculum and our technical offerings not only establish solid academic foundations but also open doors to top global universities.

Join us in building a future of limitless opportunities and unparalleled success. In addition to our schools, Prime School International has examination centers in various locations across Portugal and around the world.
