This study explores strategies in four communities with unusually high rates of enrollment among low-income immigrant families and negligible (or nonexistent) gaps in enrollment between children of immigrants and children of US-born parents. We focus on children's involvement in state-funded preschool initiatives, also known as prekindergarten, in Dearborn, Michigan; Atlanta, Georgia; King County, Washington; and Houston, Texas. These communities are situated within diverse preschool and immigration policy contexts and represent a mix of old and new immigrant destinations, homogeneous and heterogeneous immigrant populations, and countries of origin. We selected these communities to provide a range of perspectives, seeking to identify common themes and key strategies as well as site-specific adaptations to preschool enrollment barriers. Understanding how to reduce barriers to preschool access for immigrant families is key to informing preschool programs and policies in states and communities nationwide. The analyses in this study are based on individual and group interviews with parents and stakeholders. Between November 2016 and February 2017, we spoke with 134 parents from immigrant families and 106 stakeholders across the four study sites. (author abstract)
