A number of reports in the US have highlighted the country's need for improved second language skills for both national security and economic competitiveness. The Language Flagship program, launched in 2002, aims to raise expectations regarding language proficiency levels at the post-secondary level and to address structural gaps in the curricula of many L2 programs. This federally funded program provides opportunities for US undergraduate students in any specialization to reach a professional level of competence in a targeted second language by graduation. This volume highlights innovative practices that enable students to achieve this goal - even those with no exposure to the second language prior to university. This book explores the rationale and history of the federal program and showcases models and strategies of existing Flagship programs.
