About us

The Board of Directors of Prime School International

Prime School International's leadership, headed by founders Dr. Edith Reina and Eng. Carlos Miguel Almeida, has been dedicated to educating youth in Portugal and Europe for over a decade. Dr. Reina's background in economics and her 13-year tenure as the Costa Rican Consul General in Portugal earned her recognition for promoting international diplomacy and commercial relations with Costa Rica. Eng. Carlos Almeida, a lead engineer at Skysoft, contributed to aerospace advancements, notably in Brazil.


Their vision for an institution merging diplomatic expertise with scientific knowledge materialized into Prime School, offering a curriculum addressing global challenges in diplomacy and aerospace science. This attracted educators passionate about preparing students for careers in diplomacy, aviation, and space exploration.


Driven by their commitment, Prime School began in Sintra, expanding to Estoril in 2018 and Lisbon/Alvalade in 2023. Historian Dr. Ana Magalhães Pereira and Eng. Francisco Saraiva joined, enhancing leadership. Melissa Ann's leadership at the Sintra campus created a nurturing environment for young learners.


Today, Prime School International, with three campuses and online services, is a leading international and boarding school. Guided by a devoted Board of Directors across Lisbon, Cascais, Estoril, and Sintra, the institution maintains high educational standards, prioritizing community welfare, and achieving ISO 9001 certification for educational quality in Portugal.



Locations and educational offerings of Prime School International

Prime School International, nestled in Portugal's renowned locales of Cascais, Estoril, Lisbon, and Sintra, is an integral part of the extensive global educational network linked with the University of Cambridge, spanning over 160 countries. Our campuses serve as not just educational hubs, but also as centers of global connectivity and innovative learning.


With a legacy spanning over 15 years, we celebrate the exceptional achievements of our alumni as they journey from childhood to adulthood with us. Currently, Prime School International thrives with over 400 students across three campuses: Sintra (ages 3 to 11), Estoril (ages 11 to 18), and the latest addition, Lisbon (ages 3 to 18).


From age 3 to 18, students dive into the Cambridge Curriculum, exclusively taught in English. For native Portuguese speakers, we offer a bilingual approach with classes conducted in both English and Portuguese, tailored to individual preferences.


Upon reaching the 9th grade (14 years old), students conclude the bilingual program and face a significant decision. They can continue with the renowned Cambridge pathway until the 12th grade, or opt for Technical Level 2 and Level 3 programs, focusing on practical education in fields like sports, art and design, and business.


At Prime School International, education goes beyond traditional methods. While our Cambridge Curriculum lays a solid academic foundation, it also paves the way to prestigious universities worldwide. Additionally, through our partnership with Prime Technical Institute, we offer continuity in technical education, providing a recognized pathway to technical universities globally.


Recently, we've introduced online learning options for students seeking alternative educational pathways.
