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 Early Risers’s impact on students. Here’s the short version:

Early Risers is a multi-year prevention program for elementary school children demonstrating early aggressive and disruptive behavior. The intervention model includes two child-focused components and two parent/family components. The Child Skills component is designed to teach skills that enhance children’s emotional and behavioral self-regulation, positive peer relationships, and academic success.

The evidence for Early Risers covers students in kindergarten through 2nd grade.

The outcomes examined include: academic achievement, emotional/internal behavior, external behavior, and social outcomes. Here’s what the evidence suggests about Early Risers’s impact on each outcome:

  • Academic achievement: Positive impact (an average student would be expected to improve by 3 percentile points)
  • Emotional/internal behavior: No detectable impact
  • External behavior: Positive impact (an average student would be expected to improve by 4 percentile points)
  • Social outcomes: Positive impact (an average student would be expected to improve by 7 percentile points)

The studies looking into Early Risers had student samples that were in urban and rural areas in Minnesota, had students who were White and Black and were male and female.
