The CPRE/CRESP evaluation of Reading Recovery was one of the largest and most rigorous studies of an educational intervention ever conducted. It found treatment effects that are among the largest observed from an instructional program. The study therefore offers strong evidence of the impact of Reading Recovery on the reading skill of struggling 1st graders. In addition, it demonstrates the feasibility of effectively scaling up an intervention.
The study also revealed that some schools' Reading Recovery programs are more effective than others, and that differences in teachers' instruction and in schools' embrace of the program may contribute to variation in school-level impacts.
