This brief summarizes the results from Child Trends' evaluation of the Character Development Learning Institute (CDLI), drawing from interviews, program observations, and surveys of staff and volunteers from many of the 208 Ys that participated in the final phase of the CDLI (see Appendix 3 for a summary of Ys in each phase). Child Trends has served as the evaluation and research partner for the CDLI since 2017, when the CDLI debuted its framework for a small cohort of Ys in what they called the "Translate phase" (Redd et. al., 2017; Stratford et. al, 2018; Redd et. al., 2019; Lantos et al., 2019). The data presented here were collected from fall 2019 to spring 2020. Following a brief summary of key findings, we provide background on the CDLI, describe the study methods, and offer detailed findings on the outcomes of the study.
