International Schools Services

International School Services

We have worked with International Schools Services (ISS) to help open and manage the school, as well as recruit top-notch teachers from all around the world.  ISS manage works with more than 500 international schools and thousands of educators each year, creating the largest global footprint in international education support. Since its inception in 1955, ISS has launched and managed more than 110 international schools; placed approximately 50,000 educators; and developed ground-breaking learning programs, such as the World Language Initiative and Level 5 Creativity & Innovation Hubs. With its headquarters in Princeton, USA, ISS currently owns or operates nearly 20 international schools around the world and promotes innovation and best practices for global education through its core services that include founding and managing student-centered, future-oriented schools. ISS staff has extensive experience in all aspects of international education, with most senior leaders having served as Heads of Schools across a variety of continents.

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 Common Ground Collaborative (CGC): United Lisbon joins a group of leading international schools around the globe in building a highly innovative learning ecosystem throughout Early Childhood, Primary and Middle School.
  • 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.
