Implementation of Three Language and Literacy Interventions in Project Upgrade

Project Upgrade was a two-year randomized controlled trial (RCT) to test the effectiveness of three different language/literacy interventions on preschool-age children’s language and emergent literacy skills.

The evaluation found significant impacts prior to school entry for two of the three interventions on children’s language and emergent literacy skills. For the two interventions where significant impacts were found, there were impacts on both students whose teachers had received the curriculum training in English (English dominant teachers) and students whose teachers received the training in Spanish (Spanish dominant teachers), but the impacts were generally larger for the students with Spanish dominant teachers.

After the experiment ended, we followed children from the original Upgrade study to determine whether the impacts of the interventions observed in the original study persist as children progress through their first, second, and third grade years of elementary school. This research brief describes the design of and findings from the original evaluation and the follow-up study.
