Why Prime · independent since 2003

An independent Cambridge school, still led by the people who built it.

Since opening its first campus in 2003, Prime has remained faithful to the vision on which it was founded: to provide an outstanding international education while ensuring that every child is known, valued and supported as an individual.

Our leadership team remains actively involved in the daily life of the school, working closely with students, families and staff to foster a culture of excellence, care and ambition. This personal approach ensures that every student is encouraged to grow in confidence, develop their talents and fulfill their full potential.

Our story

How Prime began.

In 2003, Dr. Edite and Eng. Miguel founded Prime School International in Lisbon, with a clear conviction: that Portugal deserved a school to stand alongside the best in the world, not by copying them, but by building something distinctly its own.

British academic rigour, Portuguese warmth, and a school committed to developing character, not only delivering results.

That conviction became three campuses and one continuous Cambridge pathway from age 3 to A Level, with graduates now at Oxford, Cambridge, LSE, Imperial and leading universities across more than 30 countries. And through every year of growth, one thing hasn't changed: Prime is still independent, and still led by the family that started it.

Mission & values

We exist to inspire confident, compassionate and intellectually curious young people who are ready to thrive in a changing world. We believe education should achieve far more than academic success—it should shape character, broaden horizons and create opportunities that transform lives.

Excellence
Cambridge rigour, externally examined, held to an international standard, not assessed only in-house.
Integrity
We say what we mean and we keep what we promise.
Respect
Every child known as an individual, not reduced to a result, ranking or label.
Innovation
Evidence-led teaching, and progress followed closely for each student.
Community
A school small enough to feel personal, with families from many nationalities.
What we're built on

Three guiding principles.

Every decision at Prime, academic, pastoral, operational, comes back to three founding ideas. They are what makes the school recognisable at any age and on any campus.

01
British academic
rigour

The full Cambridge pathway, from Early Years to A Level. Analytical thinking, academic discipline and independent enquiry are built systematically from age 3, with external assessment at key stages.

02
Every child followed
closely

Each students' progress is monitored individually across subjects and wellbeing. Support is delivered early on. Parents follow it through a secure portal, no child quietly slips behind.

03
Portuguese
warmth

British educational excellence meets the warmth and hospitality for which Portugal is known for. We combine high academic standards with a deeply personal approach, where every child is recognised as an individual and every family is welcomed with care, respect and genuine support. For international families, Prime offers not just an outstanding school, but a community in which to belong.

Pedagogical excellence

Educators who inspire.

At the heart of Prime School International’s success is a highly qualified and experienced teaching team. 

We invest significantly in recruiting, developing and retaining outstanding teachers from Portugal and around the world. Our educators bring extensive classroom experience across British, Portuguese, German and international educational systems, and many hold advanced qualifications in their subject areas. Beyond their academic credentials, they share a deep commitment to education and to inspiring every student to achieve their full academic and personal potential.

01
Individual Profile

Every student begins their journey at Prime with a comprehensive academic and developmental profile. By understanding their strengths, needs, interests and aspirations from the outset, we can shape a learning experience that is both personal and purposeful.

02
Real-Time Monitoring

Our AI-supported monitoring system provides continuous insight into each student's academic progress and personal development across every subject and area of pastoral care.

Dedicated mentors, tutors and school psychologists support each student’s academic and experience. No child is left unseen.
