All of inlingua’s proprietary materials are created and developed at our Pedagogical Services Center in Bern, Switzerland. They are unique and regularly updated, and undergo a rigorous development process, including piloting at inlingua centers prior to publication. Your materials will include a textbook, workbook, verb book, and audio CDs. There is a progress test every five units, and your instructor will receive a Trainer Resource Pack that includes lesson planning guidelines, communicative activities, and additional training resources.
