The Intercultural Language Teaching and Learning in Practice (ILTLP) Project is a large scale, national professional learning program designed to extend the understanding and practice of language teachers with regard to intercultural language learning. The latter is an orientation to language learning that underpins the National Statement and Plan for Languages Education in Australian Schools (MCEETYA, 2005). This paper describes the ILTLP Project, its design, goals, and outcomes. It offers a rationale for and a description of an intercultural orientation.
