Today in the U.S., more than 4 million elementary and secondary students require language assistance, and growth of the English-language learner (ELL) population is expected to continue. Thus, school staffs must be prepared to meet challenges that will arise because of the changing population and an increase of ELLs. School districts that are prepared to manage population changes will be able to offer more effective instruction and services and avoid difficult transition periods that affect teachers, administrators, and students and their families. Cultural proficiency will be an integral component for shaping a school environment to enable ELLs to perform optimally. This article describes how Wescosville Elementary School, a suburban school near Allentown, Pennsylvania, prepares for an increase in ELLs by incorporating culturally proficient instruction.
