This randomized controlled study evaluated the effectiveness of the Lexia Core5 Reading intervention on students aged 4-6 in Northern Ireland. Ninety-eight primary school students with weaker reading skills were randomly placed in either a treatment group that received the Core5 intervention or a control group that did not. Core5 users experienced significantly greater gains than the control group in standardized measures of blending and non-word reading.
- Core5 users demonstrated significantly greater gains on measures of blending and non-word reading than control group students
- In the treatment group, student gender and English as a first or additional language were not predictive of blending scores indicating the program was successful across subgroups.
- Analysis of a 2-month follow-up indicated that gains in blending, non-word reading, and phoneme segmentation were maintained in the treatment group.
