The RAND Corporation is conducting a multiphase evaluation of the initiative, including an implementation study of the four pillars that underlie Big Lift--The Big Lift Implementation Study: Final Report--and a series of annual descriptive analyses focused on the outcomes of children who received Big Lift services. The first report, Big Lift Participation and School Entry Indicators: Findings for the 2016-2017 Kindergarten Class, focused on the early education experiences (prior to kindergarten entry) and kindergarten readiness of the 2016-2017 kindergarten class. This Technical Appendix provides details of data analyses described in the second report in the series of outcome studies, in which we follow up on the 2016-2017 kindergarten class by presenting data on their reading outcomes measured at the end of kindergarten and start of first grade. We also describe the experiences and outcomes of the 2017-2018 kindergarten class measured at kindergarten entry. (author abstract)
