The following qualitative study examined how Reading First Literacy Coaches refined their literacy coaching to meet the cultural and linguistic needs of Hispanic English language learners (ELLs) in 30 elementary schools located along the US Mexico Border. Data were gathered from the coaches through written surveys and a focus group. Findings from the coaches' practices identified three themes: 1) Coaches understood bilingual programs and the theory underlying such instruction; 2) Coaches supported teachers of ELLs by sharing their knowledge and experiences about ELLs; and 3) Coaches faced challenges in meeting the needs of teachers of Hispanic ELLs. This study is an addition to the literature that describes and contextualizes the work of instructional coaches. It has practical implications for schools seeking to build the capacity of teachers of ELLs. Guidance is suggested related to hiring coaches with special dispositions and the professional development of existing coaches.
