International Accreditation and Memberships

It is of utmost importance to us to ensure highest quality in our educational programs. This is achieved through the implementation of rigorous standards and employing faculty and leadership with a long-standing experience and successful track record in international education. To spark a regular reflection how we can still advance and innovated the education at United Lisbon, we measure ourselves at highest external standards set by leading global educational institutions such as:

  • The International Baccalaureate Organization (IBO): United International School Lisbon is a candidate school* for the Diploma Programme. This school is pursuing authorization as an IB World School. IB World Schools share a common philosophy- a commitment to high-quality, challenging, international education- that we believe is important for our students.
  • The New England Association of School’s and Colleges (NEASC): We have embarked on the process of receiving accreditation from NEASC, which will be completed once the school starts operating.
  • The International Primary Curriculum (IPC): United Lisbon International School is now the first international school in Portugal joining a group of more than 1000 schools in over 90 countries offering the International Primary Curriculum and the International Early Years Curriculum.
  • The Mediterranean Association of International Schools (MAIS): United Lisbon is a member of the network of international schools in the Mediterranean that fosters partnerships and creates opportunities for teacher engagement and student learning beyond the school itself.

* Only schools authorized by the IB Organization can offer any of its four academic programmes: the Primary Years Programme (PYP), the Middle Years Programme (MYP), the Diploma Programme (DP), or the Career-related Programme (CP). Candidate status gives no guarantee that authorization will be granted. For further information about the IB and its programmes visit http://www.ibo.org.
