Research

Once partnered with LXD Research to support educators in understanding the impact of Once tutoring in their schools. Here is the full Once-iReady Research Report for 2023-2024 that summarizes the implementation of Once and presents outcomes from three schools that used the i-ReadyⓇ literacy assessment and provided beginning-of-year (BOY) and end-of-year (EOY) literacy data for 168 kindergarten students enrolled in the Once program. At the beginning of the year, the students' median rank nationally was at the 38th percentile (i.e., they scored worse than 62% of the nation’s kindergarteners), but by the end of the year, their median rank was at the 67th percentile (i.e., better than all but 33% of the nation’s kindergarteners). If these students had only made a year’s worth of growth (which, sadly, so many American students do not even achieve), they would have kept pace with the rest of the country and their percentile rank would have remained at the 38th percentile. Their jump to the 67th percentile reflects a pace that accelerated well past their national peer group.
