The study examines the role that university English to Speakers of Other Languages (ESOL) programs play in shaping inservice teachers’ work with English Language Learners (ELLs). The findings reveal that the ESOL endorsement program contributed positively to Wheatland Elementary teachers’ preparation for their transition to becoming a district ESL site. The results show that there was an increase in an appreciation of the use of students’ first language to facilitate comprehension of content and promote bilingualism. These results suggest that well-planned university programs influence even very experienced teachers and those who may be ambivalent toward ESOL endorsement mandates, and policies that limit the requirements for those seeking state ESOL endorsement may be ill advised.
