ISS-Oeiras - International Sharing School
Lorem Ipsum Dolor

Why choose International Sharing School Lisbon? 

We empower children to live an extraordinary life through education. Together, we help every child feel settled in their local community today – and equip them with the multicultural awareness, English and Portuguese skills to flourish, no matter where their future leads.

We aim for excellence every day

As an IB World School, we offer the International Baccalaureate (IB) curriculum in English from age 1 to 18, beginning a lifelong love of learning that endures long after graduation. 

  • The IB is recognised by leading universities for nurturing inquisitive, knowledgeable young people with strong principles and communication skills.
  • Many of our teachers are IB experts who assess students from other schools across Europe and use their expertise to inspire our students to achieve their best. 
  • Our students achieve above the world average in both the Middle Years Programme (MYP) and the Diploma Programme (DP).
  • We offer a wide range of subjects at Diploma level which helps our students select subjects that match their passions and chosen university pathways.

Our community is one global family

In a multicultural world, working with people from different backgrounds is an essential skill for success. We nurture our global family by celebrating everybody’s heritage and understanding everybody’s perspective. 

  • We are home to students from over 50 nationalities allowing us to explore the world from different perspectives – and creating a community built on mutual understanding and respect.  
  • Many of our teachers speak Portuguese, Spanish, French and Russian giving our students the confidence to express themselves and be understood while they’re working on their English.
  • Our teachers get to know every student as an individual making sure they feel seen, heard and valued. In fact, many of our graduates say they really miss their teachers! 
  • Through our school house system every student finds a group to belong to with peers to welcome them and friendships that stretch across age groups. 
  • Our inclusion and SEN teams help every student participate regardless of their ability, background, personal circumstances, or developmental needs.

Our students think like entrepeneurs

We nurture learners who explore with curiosity, act with initiative, and achieve with courage – helping our students develop the real-world skills to solve real-world problems. Explore how entrepreneurship grows with your child at every stage of their learning.

  • Project-based learning transforms our lessons into challenges encouraging students to research and collaborate more deeply, leading to better academic outcomes.
  • Learning outdoors gives our students the space to learn interactively and the freedom to think creatively – all while supporting their physical and mental wellbeing.
  • Our students enjoy diverse experiences every day. From performing arts to Model United Nations, our Sharing Star programme enriches our daily timetable.
  • We offer inspiring entrepreneurial programmes from building an EV race team or working with CERN scientists to volunteering at local animal shelters and care centres.
