In 2005, the Monterey Institute of International Studies became an affiliate of Middlebury College, one of the country's top liberal arts colleges. The new partnership ensures that the Institute can continue to grow and extend its educational mission, in cooperation with a larger institution also renowned for its expertise in international education, language teaching and cultural studies.

Middlebury offers its students a broad curriculum embracing the arts, humanities, literature, foreign languages, social sciences, and natural sciences.  The undergraduate college is enriched by its other programs. Every summer, the main campus in Vermont is transformed into an institution single-mindedly devoted to the study of nine foreign languages and cultures.

There is also an overseas dimension to Middlebury College. The C.V. Starr-Middlebury Schools Abroad are located in Belo Horizonte, Berlin, Bordeaux, Buenos Aires, Concepcion, Cordoba Ferrara, Florence, Getafe, Guadalajara, Hangzhou, Irkutsk, La Serena, Logroño, Madrid, Mainz, Montevideo, Moscow, Niteroi, Paris, Poitiers, Xalapa, Santiago Segovia, Temuco, Tucumán, Valdivia, Valparaiso and Yaroslavl. These schools enroll more than 300 undergraduate and graduate students who seek to further their foreign language skills and immerse themselves as fully as possible in the host culture through academic study as well as direct experience.
