Editorial Review
Lexia Core5 is a science-of-reading-aligned adaptive program for pre-K through grade 5 that provides structured phonics, word recognition, and comprehension instruction with real-time screening data and teacher alerts for at-risk students. Its evidence base is among the strongest in the EdTech sector, with multiple randomised controlled trials showing significant reading gains, and the curriculum is explicitly aligned to the Science of Reading framework. The fully paid model requires district investment, but the outcomes data make it one of the most defensible literacy tool purchases available.
