As a nonprofit organization, International Schools Services (ISS) works with more than 500 international schools and thousands of educators each year across its suite of services, 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; developed ground-breaking learning programs, such as the World Language Initiative and LEVEL 5 Creativity & Innovation Hubs; processed about 15,000 school supply orders annually; and stewarded over 75 schools.

With its headquarters in Princeton, NJ, USA and locations in China and Bahrain (starting in the 2018-2019 school year), ISS currently owns or operates nearly 20 international schools around the world and promotes innovative best practices for global education through its core services that include: founding and managing student-centered, future-oriented schools; recruiting world-class educators; providing cutting-edge professional learning opportunities; sourcing essential school supplies; and stewarding school foundations. Our team has extensive experience in all aspects of international education, with most senior leaders having served as Heads of School across a variety of continents.

A Little History

ISS-founder-Arthur-Sweetser International Schools Services (ISS) was founded in 1955 by Arthur Sweetser. During his career as a US Government emissary, Sweetser championed global collaboration and peace by supporting the formation of both the League of Nations and the United Nations.

With his vision of a more connected world, Sweetser held international education in high esteem. He was a seminal figure in the growth and development of international schools, helping to found The International School of Geneva, the United Nations School (UNIS), the International Baccalaureate (IB), and ISS.

Today, ISS carries on Sweetser’s innovative spirit in our multifaceted support of international education. We are committed to creating world-class schools that educate students to be thoughtful, imaginative global leaders. Our schools showcase the very best practices in modern education, and at the same time embrace their local cultures.
