A new study from LXD Research looks at the 551 kindergarten students from 35 schools in two school districts in the Southeast that use Fastbridge for assessment, implemented Once, and provided both beginning-of-year (BOY) and end-of-year (EOY) data for the 2024-25 school year.

As a group, students started the year in the 19th percentile nationally, and, after Once tutoring, they ended the year in the 29th percentile nationally. If those students had made a year’s worth of growth (which is sadly not the norm for so many American students), their percentile growth would have been 0. So they advanced in rank 10 places (out of 100) over the course of the year.

But dive deeper into the report and you’ll learn a lot more. 

One thing every tutoring provider knows is that dosage matters!

Students who completed 80 sessions or more were seven times more likely to be at low or no risk by spring than those who completed fewer than 40 sessions.

80 sessions might sound like a lot, but it’s just 20 hours of instruction spread across the school year (less than 2% of the hours students are in school).

So why didn’t every student receive at least 80 sessions? In some cases the student was absent. But in others the school support staff member providing the instruction was absent or assigned to other duties. Tutoring only works when it’s actually delivered, and at Once we obsess over delivery metrics to ensure schools deliver as much as possible.

Please read the study, let us know what you think, and contact us if you think Once would be a good fit for your school or district.

And we’ve got more studies coming, so stay tuned!
