Welcome to the International English Center

The International English Center (IEC), at the University of Colorado Boulder, was established in 1975. It offers students from all parts of the world a unique opportunity to learn the English language in a stimulating academic atmosphere, which is at the same time friendly and welcoming. The IEC is fully accredited by the Commission on English Language Program Accreditation (CEA). CEA was established to promote excellence, assure quality, and recognize programs that meet accepted standards in curriculum, faculty and student services. The IEC is also a member of the consortium of University and College Intensive English Programs in the U.S. (UCIEP), and English USA (formerly known as the American Association of Intensive English Programs). IEC faculty are professional and experienced instructors who specialize in the teaching of English as a Second Language (ESL). They are required to have M.A. or Ph.D. degrees. Many have experience teaching intensive English in the U.S. and overseas to adult students from many language backgrounds.
