This study investigated the impact of home literacy environment (HLE) on the acquisition of English as a second language (L2) and reading skills in Chinese-speaking kindergarten children. The sample was 354 kindergarten children (mean age: 60.37 months, SD = 7.25; 186 boys, 52.5%) in Hong Kong, China. Mothers completed a questionnaire measuring family socioeconomic status (SES), parent-directed HLE, and child-initiated HLE in learning English. Children were assessed on their English language and reading skills: phonological awareness, letter knowledge, vocabulary, word reading, and rapid naming. After the role of family SES was controlled, child-initiated HLE instead of parent-directed HLE was found to uniquely predict phonological awareness, letter knowledge, and rapid naming, which jointly contributed to English word reading. Family SES was also a significant correlate of cognitive-linguistic skills and English language skills. The findings highlighted the importance of child-initiated HLE in promoting children's English language learning as L2.
