The INCAE Business School (Spanish: ''Instituto Centroamericano de Administración de Empresas, INCAE'') is a private business school. INCAE was founded in 1964 with the support of the United States government and other Central American countries.  The institution has a close affiliation with Harvard University, as it had played a part in its foundation. The Francisco de Sola campus in Managua, Nicaragua was the first to be established (1964), the Walter Kissling Gam campus in Alajuela, Costa Rica was the second established in 1984. The latter was made the main campus following the lack of government support during the 1980s; in fact the Managua campus was actually closed for most of this time. It then reopened in 1990 after democracy was restored in Nicaragua; however, the main campus remained in Alajuela.
