This study examined the family language policies (FLP) of Korean American parents and how the language practice, management, and ideology components of their FLP and demographic variables predict maintenance of the home language. Results of a large-scale (N = 480) survey show that different sets of FLP and demographic variables contributed to a model that predicted retention of oral versus literacy skills. Child gender, age of English exposure, and parental attitudes toward bilingualism were strong predictors of oral and literacy skills in the home language. Whereas length of settlement and language-practice patterns predicted maintenance of oral skills, language-management strategies were required for retention of literacy skills.
