UPSTART is a federally funded i3 validation project that uses a computer-based program to develop the school readiness skills of preschool children in rural Utah. Researchers used a randomized control trial design to evaluate the impact of the program in advancing children's early literacy skills. Preschoolers in the experimental group were randomly assigned to the UPSTART Reading software, while control group students were assigned to UPSTART Math. Standardized early literacy assessments were administered prior to program commencement and upon completion. Results revealed that there was a significant difference in children's mean scores on measures of letter knowledge and phonological awareness, after controlling for prior knowledge, missing pre-test data, and children's school district between those who participated in UPSTART Reading and those in the comparison group. There were no differences between the two groups on assessments measuring vocabulary and oral language or listening comprehension.
