The home literacy environment (HLE) is a key contributor to children’s early literacy development. A broad conceptualization of the HLE includes four aspects representing parent-child literacy interactions, available resources for the child, parental characteristics, and parents’ educational interests and beliefs. Although there have been many parental surveys of the HLE, they have narrowly focused on the frequency of shared book reading or have only added the frequency of code-related activities without addressing the manner in which parents interacted with their child during these activities. Drawing from experimental and correlational literature on evidence-based strategies related to interactive reading and child engagement, we developed a more extensive HLE measure intended to better capture the frequency and nature of HLE interactions inclusive of shared reading, language interactions, and code-related learning opportunities. We report on measurement characteristics, including psychometric features and predictive validity findings. We discuss challenges remaining to best characterize the HLE among diverse populations.
