Given the need to enhance the academic language and early literacy skills of young children from low-income homes and the importance of the home literacy environment in supporting children's development, the purpose of this qualitative study was to better understand the home literacy environment of low-income African-American and Latino mothers of preschool children living in the United States. Specifically, research aims were to examine home literacy environment practices, beliefs and influential factors as well as to compare the home literacy environment of African-American and Latino, specifically Puerto Rican, families. Semi-structured interviews were conducted with 10 African-American and 10 Puerto Rican mothers. Data were analysed using the consensual qualitative research method. Twelve themes were identified: provision of educational materials, engagement with books, focus on print, implicit language opportunities, focus on other pre-academic skills, social interactions with books, influence of school, influence of other adults, parents' reading interest/ability, child's reading interest, parents' commitment to child's success and family stressors. Few differences emerged between African-American and Puerto Rican mothers. Implications for language and literacy intervention development are discussed.
