CAISL meaning in International ?

The Carlucci American International School of Lisbon (known as CAISL) is a prominent private international school in Linhó, Sintra, a wealthy suburb of Lisbon on the Portuguese Riviera. Founded in 1956, CAISL is the oldest American school in the Iberian Peninsula and the only U.S. State Department school in Portugal. It is named in honor of Frank C. Carlucci III, former U.S. Ambassador to Portugal and U.S. Secretary of Defense. Hillary Clinton, at the time First Lady of the United States, officially inaugurated CAISL's current campus in Linhó in 1998.

CAISL operates as a dual American and International Baccalaureate (IB) program and is one of Portugal's most expensive schools. CAISL's student population is largely international, with most students connected to diplomatic missions and embassies in Lisbon, followed by Portuguese nationals, and a sizable minority of Americans. CAISL has numerous partnerships with institutions, such as the prestigious Gulbenkian Foundation, to support research initiatives into teaching methods, philanthropic outreach, and to host international conferences and cultural exhibitions. In 2016, Hewlett-Packard (HP) awarded CAISL with the HP Award for Innovation in Education. CAISL alumni have gone on to hold influential positions, both abroad and in Portugal, and have included Grammy Award-winning artists, Presidents of Portugal, Yamaha Artist-awarded concert pianists, and world-renowned journalists.
