Although biliteracy plays a vital role in academic achievement, there has been little research on the unique needs of female and male English language learners. Becoming biliterate is a complex process, compounded by other variables such as 1st-language background, class, culture, and gender. Among these variables, gender has been the least examined and reported for English language learners in the United States. This exploratory quantitative study investigates the interplay between gender and biliteracy in a diverse urban school district. The quantitative data demonstrate gender variations across all years and grade levels and on both English and Spanish assessments.
