Our History
Prime School International was one of the first schools to obtain the Cambridge Curriculum certificate in Portugal, together with the teaching equivalence of the Portuguese Ministry of Education. This curriculum is considered by the Group to be the best that fits in with its philosophy, besides its international recognition and great prestige for its student-centered approach. Nowadays, we also teach students the American High School Diploma, from grade 10 to grade 12, in Estoril upon request.
We have been following this teaching method since 2005, adding to the value of 21st-century education, and the investment in the future of our planet through our students. We started with Sintra Campus and now, besides the Sintra (College Infanta D. Maria de Portugal), we do have the Estoril Campus (International Anglo American School), where we teach the same curriculum - the Cambridge Curriculum.
Our educational community has attracted talent from all over the world and is considered one of the best schools that, through research, and innovation, prepare students aged 3 to 18 years. Prime School has the distinct advantage of a multiculturally inclusive environment. Our pedagogy addresses the emotional, social, ethical and academic needs of students in an integrated learning format. Our curriculum sets a global standard for education which both challenges and inspires our students.
The Prime School network of schools aims to contribute to the creation of a better world through education, research and innovation. At Prime School International, we believe that every student has the potential to discover and reach their full potential through our Educational Project.
Our students enter the world's best universities, subsequently contributing to the creation of new industries and job opportunities. Attending Prime School is a passport to the future, creation, determination and commitment in short make the difference.
That is why we celebrate academic achievement alongside social, physical and emotional well-being.
At Prime School, we value people’s personal growth, honesty, truthfulness, critical thinking, tolerance, diversity, creativity, determination, self-reliance, and lifelong learning.
Vision
We believe that the future can manifest itself with realities not yet foreseen, as we live in a dynamic and globalized world that is evolving at the speed of light. We believe that we need to prepare students for a world with professions that do not as yet exist, and for the challenges that permit humanity to develop its full potential. By better preparing students to develop a working capacity with mental resources, mental flexibility, reasoning, and communication, thinking orientation to problem-solving, resilience, and empathy, we firmly believe we are empowering them to be citizens of the future. Prime School curricula are your child's passport to a well-rounded and outstanding global education.
