In March 2019 Book Harvest engaged HighScope Educational Research Foundation to conduct a longitudinal Randomized Control Trial (RCT) evaluation of Book Babies. The goal of this two-site longitudinal study was to examine the impact of the five-year Book Babies intervention on parents' reading practices, children's literacy and language skills, and kindergarten readiness. The evaluation study concluded in 2020. This is the final report, which was produced after the lead principal investigator transferred her affiliation to the University of North Carolina at Chapel Hill.
