30 Years Proudly Delivering a Nationally-Leading, Prime Multilingual Education

At St. Peter’s International School, we are dedicated to building futures through competitive, high-quality education that prioritises the child’s integral development.

St. Peter’s is surrounded by the stunning sea and mountain views of Palmela, Setubal, just 30 minutes from Lisbon. As a top-ranked school in Portugal, local and overseas entrants aged 4 months to 18 years enjoy a bespoke education that enables them to flourish in a holistic, bilingual learning environment.

Our expansive 37,000 sqm campus is an idyllic educational setting for 1,500 children and young adults in our student body, all of whom are supported with specific learning objectives to guide their path towards discovery. Across the school’s fully-equipped indoor and outdoor spaces, children receive interactive lessons to support all aspects of their development.

St. Peter's International School offers the Portuguese curriculum from Preschool to Secondary, but also provides the option of an international education. We deliver the Cambridge curriculum from Grade 7 (Lower Secondary & IGCSE), and the globally-recognised International Baccalaureate Diploma Programme for senior students. Starting in September 2023, we will provide the choice to follow the Cambridge International Curriculum for Grades 1 and 5. We will gradually expand this offering to include the remaining years of the Cambridge Primary curriculum in subsequent years.

Mission & Values

St. Peter’s is an international school that provides a competitive, high-quality response to the needs of a diverse population. Its fundamental principles are centred on the integral development of the child and emphasise academic and professional success based on attitudes, practices and values that contribute to the growth of the individual.

Our mission is to develop autonomous and well-rounded students, enabling them to maximise their full potential through exceptional learning and personal development, preparing them for the future, whatever it may hold.

St Peter’s core values are centred on the integral development of each student, valuing academic and personal success, based on Rigour, Responsibility and Respect of the individual, the community and the world.


Educational Philosophy

In a world that is constantly changing and in a society that advances at an ever-increasing pace, education has taken on a leading role with a heightened sense of social responsibility. Our educators strive to instil key principles in our student body. They cultivate a positive learning environment in which children are encouraged to become people of integrity. We expect students to be rigorous, respectful and responsible and are committed to helping them attain academic excellence, relevant knowledge, and life-long social and relationship skills.


Given the cosmopolitan nature of our school in Setubal, the English language holds significant importance in our educational setting. It is incorporated into the curriculum starting from Kindergarten all the way through Secondary School. Furthermore, the acquisition of other languages such as Spanish and Mandarin Chinese is also crucial. These languages enable students to develop a profound comprehension of the foundations of Western civilization and provide exposure to diverse worldviews and cultural realities. This facilitates a transdisciplinary assimilation of knowledge and values, while also fostering enhanced competitiveness in the job market.

At the Secondary School level, students continue their tuition with the International Baccalaureate Diploma Programme – a two-year academic programme recognised by the most renowned universities around the world as the pre-university approach that best prepares young adults for entry into higher education. On the other hand, we aim to develop an appreciation of the various art forms by encouraging creativity. It is also our ambition to promote healthy lifestyles, physical activity and sports while instilling safe conduct in our students so that these elements can be practised in their daily lives.

Finally, in accordance with our guiding principles, we reiterate the great importance we give to fostering values and affections that instil a cognitive, moral and aesthetic sensibility in our students. As such, by exploring the critical spirit of every learner, we aim to promote responsibility, autonomy, citizenship and solidarity in each member of our student community.

History - 30 Years of Experience

St. Peter's International School was founded in 1993, fulfilling the dream of Isabel and Armando Simão, who aspired to create a distinguished educational institution in Portugal.

The Simão family has always pursued the mission of building self-reliant, critical, creative students, who have the necessary skills and abilities to perform well at a personal, social and professional level, thus allowing them to pursue their studies, and actively integrate into a rapidly changing and increasingly globalized society.

In 2019, as the school celebrated its 25th anniversary, St. Peter's International School joined the Inspired Education Group, becoming a part of this world-leading group of premium schools and embracing a global community.
