Utah Preparing Students Today for a Rewarding Tomorrow (UPSTART) is a home-based preschool program developed and provided by Waterford to prepare preschool children for school and future academic success. The Evaluation and Training Institute (ETI), the external evaluator of UPSTART since 2009, has prepared this report for the Utah State Office of Education (USOE) to document UPSTART's impact in its 6th year of implementation (Cohort 6/2014-2015 program year). The evaluation of UPSTART's sixth cohort moved from using a nonequivalent control group seen in previous years to a pre-test/post-test design with a statistically matched control group to assess the program's impact on developing children's early literacy skills in preschool. Our research findings cover two areas, how the program was implemented and what types of impacts it had on children's literacy. (author abstract)
