Research

Once partnered with LXD Research to support educators in understanding the impact of Once tutoring in their schools. This report is based on LXD Research's review of BOY and EOY outcome data from three schools that implemented Once with all students (168 total) in Kindergarten. 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 made a year’s worth of growth (which is sadly not the norm for so many American students), their percentile rank would have remained at the 38th percentile. Instead, these students accelerated well past their national peer group. Here is the full Once-iReady Research Report for 23-24 that summarizes the implementation and presents outcomes from schools that provided both beginning-of-year (BOY) and EOY data.
