Independent evidence to support literacy improvement
The Education Endowment Foundation (EEF) recently commissioned a large-scale, randomised controlled trial to test the impact of Lexia® Core5® Reading with groups of Year 2 pupils across multiple regions of England.
The study explored how Core5 could:
- Support struggling readers in making accelerated progress.
- Help disadvantaged pupils close the attainment gap.
- Be implemented alongside existing school provision with positive feedback from staff.
With a high evidence security rating, and the intervention deemed very low cost to implement, the trial provides trusted, independent insight into the role of adaptive technology in supporting reading development.
