From 2005 to 2009, The American Council on the Teaching of Foreign Languages (ACTFL) OPI/ILR Workshops were held in the Center for Language & Technology then known as the Language Learning Center. Training was done for speakers of the following languages: Chinese (Mandarin), Korean, Tagalog, Ilokano, Cebuano, Thai, Lao, Khmer, Vietnamese, Kurdish-Sorani, Persian Farsi, Arabic, Samoan, Slovak, Marshallese.   In addition workshops for two other projects, Diagnostics Helps and CCT, were held involving the following languages: Persian Farsi, Arabic, Korean, Chinese, Chavacano, Tausug and Cebuano. Several participants were involved in both the OPI training and the Diagnostics Helps and CCT projects.
