WWC synthesis of two randomized controlled trials (RMC Research Corporation, 2003; PCER Consortium, 2008) covering "540 preschool children enrolled in 38 preschools in New Jersey." All domain ratings were "No discernible effects."

"Based on these two studies, the WWC considers the extent of evidence for Ready, Set, Leap!® to be medium to large for oral language, print knowledge, and phonological processing, and small for early reading/writing and math."
