New Interchange is the world's most successful ESL series for adult and young adult learners at the beginning and intermediate levels. What makes New Interchange so successful is that it takes students from beginning to intermediate levels of proficiency and offers them a multi-skills syllabus integrating themes, grammatical structures, functions, and vocabulary. New Interchange emphasizes student interaction on high-interest topics with a focus on both fluency and accuracy.

New Interchange has four levels: Intro, 1, 2, and 3. The course components for each level consist of a Student's Book, Workbook, Teacher's Edition or Teacher's Manual, and Audio Program. In addition, a Video Program and CD-ROM provide supplemental practice.
