Welcome to Parsimony’s blog, where we help K-12 educators identify evidence based ways to maximize student outcomes.

This blog post is part of our What Works Clearinghouse review series. The What Works Clearinghouse (WWC) is an initiative by the Institute of Education Sciences (IES) which is the independent statistics, research, and evaluation arm of the United States Department of Education. WWC estimates the effectiveness of programs by evaluating the quality and quantity of evidence for that program.

This week’s blog post is about the evidence behind Ready, Set, Leap!® ’s impact on students. Here’s the short version:

Ready, Set, Leap!® is a comprehensive preschool curriculum that focuses on early reading skills, such as phonemic awareness, letter knowledge, and letter-sound correspondence using multi-sensory technology that incorporates touch, sight, and sound. Teachers may adopt either a theme-based or a literature-based teaching approach.

The evidence for Ready, Set, Leap!® covers students in pre-kindergarten.

The outcomes examined include: early reading/writing, general mathematics achievement, oral language, phonological processing, and print knowledge. Here’s what the evidence suggests about Ready, Set, Leap!® ’s impact on each outcome:

  • Early reading/writing: No detectable impact
  • General mathematics achievement: Negative impact
  • Oral language:  No detectable impact
  • Phonological processing: Positive impact (an average student would be expected to improve by 2 percentile points)
  • Print knowledge: No detectable impact

The studies looking into Ready, Set, Leap!® had student samples that were in urban areas in New Jersey, had students who were White, Black, and Hispanic, and were male and female.
