@IESResearch There is also promising evidence that the program positively impacted writing productivity and receptive communication immediately after the intervention and writing conventions 3 years after the intervention.

@IESResearch Based on those two studies, there is moderate evidence that Reading Recovery® positively impacted student achievement in literacy immediately after the intervention.

@IESResearch The WWC reviewed 62 studies for this intervention report. Two studies meet WWC standards and are summarized in this report. These two studies included 7,171 students in the United States and United Kingdom.

Trained Reading Recovery® teachers deliver the tutoring in daily 30-minute sessions over the course of 12 to 20 weeks. The results are summarized in an intervention report released today by @IESResearch, updating an earlier report from 2013.
