SABIS^® is an organization that manages schools worldwide. In the year 2007-2008, approximately 40,000 students were enrolled in SABIS^® schools. The distinguishing mark of these schools is their implementation of the SABIS^® Educational System, a unique system that offers a rigorous, internationally oriented, college-preparatory curriculum for students aged 3 to 18+ focusing primarily on the core subjects of English, Mathematics, Sciences, and World Languages.

The first school in what has since become the SABIS^® School Network is the International School of Choueifat.
It was founded in 1886 in the village of Choueifat, a suburb of Beirut, Lebanon. Now, the SABIS^® School Network consists of Member and Associate Member schools that operate in the private and public sectors. These schools all implement the SABIS^® Educational System, although each of them remains financially and administratively independent.
