Excellence in Global Education

Explore the academic excellence offered by Prime School International, strategically situated in prestigious locales across Portugal - Cascais, Estoril, Lisbon, and Sintra. As a prominent member of the esteemed global educational network Cambridge International, spanning over 160 countries, our institutions have garnered international acclaim over the years.

At Prime School International, we provide a comprehensive educational journey from early childhood at age 3 through to adulthood at 18.

During the foundational years from 3 to 13, encompassing primary and early secondary education, students are presented with two distinctive pathways: the Cambridge curriculum, exclusively delivered in English, or a bilingual approach integrating Portuguese, fostering linguistic proficiency across subjects.

Distinguished by its innovative approach, education at Prime School International transcends conventional paradigms. Both our Cambridge curriculum and technical programs forge robust academic fundamentals, paving the way to esteemed global universities.

As students progress from ages 14 to 16, entering Year 10, they encounter a pivotal juncture: to pursue the esteemed Cambridge trajectory with globally recognized assessments like IGCSE, or to embrace the Prime Technical Curriculum. This specialized curriculum emphasizes practical and technical education, offering specialized tracks including Sports Management, Art and Design, Business, Hospitality, and Informatics.

Upon reaching the ages of 17 and 18, during Year 12 to Year 13, students are empowered to tailor their educational experience. They may opt for A Levels or explore more specialized pathways. The latter option encompasses diverse fields such as Sports Management, Art and Design, Tourism, Media Production, Theatre, and Performing Arts, preparing students for tertiary education focused on applied skills.

In addition to our physical campuses, Prime School International extends its reach through online support via our educational hubs, fostering connectivity within our international community across Portugal and globally. Embark on a journey of boundless opportunities and unparalleled achievement with us at Prime School International.
