The "State-Funded Preschool in the Last Frontier: Alaska's Pre-Elementary Grant Program" study examined the implementation of Pre-Elementary Grant (PEG) programs in Alaska, the characteristics of PEG districts and the students served, and the student outcomes related to participating in state-funded preschool, including participating in a PEG program. Based on analyses of documents, interviews, and administrative data, the study found that PEG districts served a higher proportion of Alaska Native students, English learner students, and students in rural remote schools than did non-PEG districts and that these differences increased between 2016/17 and 2018/19 as more districts received funding. The study findings have important implications for Alaska's efforts to expand preschool and might also be of interest to other predominantly rural states that are considering similar efforts. Specifically, the implementation findings can help practitioners, program directors, and state agency staff members in Alaska provide more targeted support to districts and modify the grant program in future years. This document presents the following four appendixes that accompany the study: (1) About the study; (2) Methods; (3) Supporting analysis; and (4) Interview and document analysis.
