The Dallas County Community College District offers an intensive English program called the American English and Culture Institute (AECI) for international students preparing to study in American colleges and universities or planning to work in fields where English is the primary language. The AECI is a year-round program of English and culture study that is offered in ten-week sessions and divided into proficiency levels of one through five. Students who score higher than 117 but less than 197 on the computer-based TOEFL or who score higher than 430 but less than 530 on the paper-based TOEFL will be considered for the AECI.
