This article provides school-based consultants with an overview of the English language learner (ELL) student population and common programs available to ELL students (such as English-only programs, pull-out English as a second language [ESL], content-based ESL, transitional bilingual programs, maintenance bilingual programs, and two-way or dual language bilingual education programs). Past and current research examining bilingual education programs and guidelines and recommendations for the application of bilingual education knowledge to consultative practice with school personnel and culturally and linguistically diverse parents are discussed. Because of the paucity of research regarding school-based consultation related to bilingual education issues, guidelines and recommendations are presented within the larger framework of multicultural and cross-cultural consultation. Recommendations for future research regarding school-based consultation related to bilingual education issues are provided.
