Waterford Raises Student Achievement in Both Reading and Math

Children using Waterford consistently achieve more than a year of growth beyond expectations. Through engaging books, characters, songs, and interactive activities, children build literacy and math skills that last.

Evidence and Research

PreK students who participated in Nevada’s UPSTART program had strong early literacy and math outcomes. The program’s effects were large enough to have a substantive impact on children’s learning and development, with a 42% return on investment. Benefits were similar for dual‑language and monolingual learners.

Children in Indiana who were randomly assigned to use a 15‑minute‑a‑day computer‑adaptive reading program ended kindergarten with stronger reading scores than peers receiving only teacher‑led instruction. Higher scores were observed across all backgrounds, indicating that adding adaptive technology can give young learners extra support in learning to read.

Children using UPSTART’s reading software scored higher in letter knowledge and phonological awareness than those using math software, even after accounting for prior skills and district differences. The study shows that computer‑based early literacy instruction can effectively strengthen foundational reading skills for rural preschoolers.

PreK children across five states who used Waterford’s computer‑assisted literacy program scored significantly higher overall and in blending, letter sounds, and letter recognition subskills than peers using the math/science program. Benefits extended across demographic groups, including multilingual learners and children experiencing poverty, showing CAI’s potential to strengthen early literacy skills.

Children in South Dakota and Wyoming who used Waterford’s computer‑assisted literacy program during the summer before kindergarten scored higher in overall literacy—especially blending and letter recognition—than peers using the math/science program. Benefits held for children experiencing poverty and for students of color, showing strong, equitable summer learning gains.

Rural preschoolers who used Waterford Upstart’s Summer Learning Path before kindergarten scored significantly higher on measures of early math skills. The adaptive, at‑home program helped address limited early‑education access and pandemic disruptions. Results show technology‑based summer learning can strengthen school‑readiness math skills for rural children.

Nevada preschoolers randomly assigned to the Upstart math program scored higher in math concepts and applications than those randomly assigned to the reading program, both after PreK and again in kindergarten. Multilingual and non-multilingual learners benefited equally. Results show early, at‑home, technology‑based math instruction can strengthen school‑readiness skills.

Preschoolers in rural Utah who were randomly assigned to use a computer‑adaptive reading program scored higher in overall literacy and across multiple reading skills than peers assigned to use a math/science program. Benefits held across all demographic groups, showing computer‑assisted instruction can strengthen early literacy and support kindergarten readiness.

UPSTART continues to strengthen preschoolers’ early literacy without hindering social development. Children using the program had statistically significant positive effects compared to control children on measures of early literacy. Increased program usage was associated with significantly higher literacy outcome scores, making consistent participation especially important for the most at‑risk families.

UPSTART continues to help preschoolers build strong early literacy skills that last into kindergarten and first grade. In 2018–19, 87% of children graduated, and those who met usage goals showed stronger outcomes. Maintaining consistent participation is especially important for supporting at‑risk families, who are more likely to miss usage requirements.

UPSTART children scored higher in key literacy skills than matched peers, and those benefits continued into kindergarten and first grade. When compared to students who attended public and private PreK, only UPSTART students had significantly positive literacy results at kindergarten entry. UPSTART’s individualized design drives its strong results.

The UPSTART Summer program helped rural rising first graders avoid summer reading loss, especially in letter naming and phonics. Results suggest UPSTART is most effective for these foundational early reading skills and can help prepare young students for entry into first grade.
