The Bay Area Foreign Language Program (BAFLP), one of nine regional sites of the California Foreign Language Project, offers ongoing, year-round professional development programs for world language educators. In addition, its leadership program prepares selected educators to assume leadership positions at their school sites, building capacity for sustainable change. Demographic data from the program reveal increased opportunities for educators to strengthen their standards-based instructional practices. Findings also indicate that the leadership program is successful in terms of participant experience, allowing educators to gain leadership skills and lend their expertise back to improving the program. Aligned to the Standards for Foreign Language Learning in the 21st Century, BAFLP's model can offer guidance to school districts in crafting effective and sustainable professional development programs.
