Learning another language is considered a key 21st century subject, something that all students should begin in elementary school. However, most school districts in Illinois do not offer students the opportunity to learn another language in elementary school. There are effective and high quality programs available to learn another language that are also mutually beneficial to English learners (ELs). District leaders in charge of planning curricular programs have choices about which programs are offered and are tasked with considering the many needs of the districts they serve. The purpose of this study was to learn about the decision making of school district leaders in Illinois to better understand what evidence they use when offering foreign language programs of instruction. This qualitative case study used data from three school districts in Northern Illinois. A slide deck for the purpose of professional learning is included at the end of this study to assist district leaders in their decision making when implementing language programs.
