Evidence of Efficacy

Get Our White Paper

This retrospective correlational study of struggling readers showed a statistically significant positive correlation between use of the Sonday System and students' reading scores. The gap between struggling readers and normally developing readers decreased during the study. The promising evidence found in the results of this study meets the Tier 3 level of the Every Student Succeeds Act (2015). Contact us for a copy of the evidence-based research.
