Program Description

Early Reading Intervention (ERI) is a supplemental reading intervention for kindergartners who are at risk for reading difficulties. Students receive 126 30-minute daily lessons in groups of 3 to 5. These focus on phonological awareness, phonics, writing, and spelling.

Program Outcomes

Two studies compared ERI to ordinary school-designed services, also to groups of 3 to 5 students at a time. The two studies had very different outcomes. In comparison to controls, one found statistically significant positive outcomes, with an average effect size of +0.39. This study qualified ERI for the ESSA “Strong” category. The other study found no differences, for an average effect size across the two studies of +0.20.
