IEC History

The International English Center opened its doors in 1975. It was one of the few Intensive English Programs (IEPs) in the state of Colorado at that time. The IEC prides itself on the dedication of its faculty and staff to the students and on its high standard of teaching.  The IEC is accredited by the Commission on English Language Program Accreditation (CEA) and is a member of the Consortium of University English Programs (UCIEP) and the American Association of Intensive English Programs (AAIEP).

The International English Center welcomes students from countries all over the world. Students from Asia, the Middle East, North and South America, Europe and Africa have attended the IEC since the mid-seventies. Over the years, responding to shifting economic and political situations around the world, the IEC has adjusted to the change in student populations. At different times, we have had an influx of students from Iran, Venezuela, the Gulf Arab States, Japan and South Korea to name a few.

The IEC is proud to celebrate our 40th anniversary in fall 2015.
