UPSTART is a pilot project established by the Utah state legislature that uses a home-based education technology approach to develop the school readiness skills of preschool children. In its third year of operation during the 2011-12 school year, the project's implementation contractor -- the Waterford Institute -- enrolled 1,168 preschool children and provided them a game formatted program of early literacy instruction delivered by personal computers and the Internet, designed to prepare them academically for kindergarten. The 1,168 children enrolled in the third year cohort, hereafter referred to as C3, participated in the UPSTART program from October 2011 through June 2012. The evaluation of UPSTART's third year of implementation used a pretest-posttest control group design to assess the program's impact on developing the children's early literacy skills in preschool.
