Home for Global Students

from 14- to 18-year-olds

Boarding Prime School is boarding day school for boys and girls aged 13 to 18 years, where fundamental traditions combine with innovative educational thinking. Academic excellence underpins life at the school, and boys are encouraged to aspire to the highest possible standards and exceed their expectations. We are also renowned for our strengths in science,, and sport. At Prime School, we believe that a complete and balanced education produces fully rounded boys. From age 13 to 18, it’s a continuity of education that enriches and prepares them for diverse and rewarding adult life. Life at Prime School is very rich and, from their earliest years, boys and girls are encouraged to take advantage of the wide range of opportunities open to them. 


The boarding school is set in a beautiful and extensive estate in the heart of Cascais - Lisbon. With easy access to Lisbon, Sintra, Estoril and Lisbon Airports, is ideally located for Portuguese and international students alike.

Academic life

Our highly qualified teaching staff are selected on their ability to communicate and inspire. The result is a vibrant, stimulating environment, where boys and girls can be happy, grow in self-confidence, thrive academically and make the most of the extensive opportunities on offer. Our curriculum is structured to provide breadth, balance and extend learning well beyond national requirements, and offers boys and girls a varied choice pic of subjects. Our academic success is demonstrated by a long history of impressive examination results at IGCSE, A Level.

 Sporting tradition

In line with our enviable sporting tradition, we aim to inspire a lifelong interest in the sport, promoting teamwork, wellbeing, fitness and, most of all, enjoyment. 


Prime School has a long-established reputation for excellence in sciences.

Strong community

As soon as boys and girls arrive at Boarding Prime School, they are welcomed into a genuinely caring community, where individuals and individuality are Prime School valued. At the center of this community are the boarding houses – boarders soon feel that their boarding house is a ‘home away from home’ during their time at the school. Boys and girls enjoy regular house trips and events throughout the year. The Secondary School and advanced levels operate independently on the same campus but join together to provide continuity of education from 13 to 18 years of age, and the warm, inclusive culture with which Boarding Prime School has become associated extends across both school.

Prime Boarding includes all meals and lodging, trips, and academic fees.
