The CLS Program provides opportunities for American college and university students to study languages and cultures essential to America's engagement with the world. 

Each summer, American undergraduate and graduate students enrolled at U.S. colleges and universities across the country, spend eight to ten weeks learning one of a dozen languages at an intensive study abroad institute. The CLS Program is designed to promote rapid language gains and essential intercultural fluency in regions that are critical to U.S. national security and economic prosperity.

CLS Spark, an initiative of the CLS Program, provides opportunities for American undergraduate college and university students to study Arabic, Chinese, Korean, Japanese, and Russian virtually at the beginning level. 

Designed to leverage best practices in online language learning, CLS Spark provides students with the opportunity to study critical languages virtually when they may not have access to studying these languages on their campuses.

The Critical Language Scholarship (CLS) Program is a program of the U.S. Department of State with funding provided by the U.S. Government and supported in its implementation by American Councils for International Education.
