Since 1959, the American Language Institute (ALI) has been providing English language instruction, assessment, and resources to support the academic and professional success of non-native speakers of English pursuing a degree at USC. The ALI offers English language courses for those students who want to improve their English as well as those who are required to take classes as a result of taking the International Student English (ISE) exam. The ALI is also responsible for testing and providing English language instruction for the university's international teaching assistants.
