The American Council on the Teaching of Foreign Languages (ACTFL) enthusiastically endorses and supports the goals of the Language Flagship initiative to develop and recognize the professional language proficiency of our nation’s future leaders. Language Flagship programs are a national model for establishing proficiency outcomes, designing instruction to target benchmarks, and systematically assessing progress towards those targets. The chapters contained in this volume examine the challenges, complexities, opportunities, and successes of the Language Flagship Initiative’s innovations for language instruction in post-secondary education.
