Lexia LETRS Training Tied to Kentucky Student Reading Gains
Event summary
- Independent Kentucky study links Lexia LETRS professional learning to improved student reading outcomes across 574 elementary schools
- Schools with higher concentrations of LETRS-trained teachers saw up to 4.26% growth in 'Proficient' students vs. 2.90% in lower-participation schools (2023-2025)
- Study analyzed data from 7,000+ educators and administrators engaged in LETRS training through Kentucky Reading Academies
- Lexia reports 698,000 educator enrollments supporting 9.4 million students nationwide
The big picture
This study provides empirical validation for Lexia's LETRS professional development model at a time when states are increasingly adopting science-of-reading frameworks. The findings come as education technology companies face growing scrutiny to demonstrate measurable academic outcomes. With 1 in 3 US school districts already using Lexia solutions, this data could accelerate adoption in remaining markets.
