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 READ 180® 's impact on students. Here’s the short version:

READ 180® is a reading program designed for struggling readers who are reading 2 or more years below grade level. It combines online and direct instruction, student assessment, and teacher professional development. READ 180® is delivered in 90-minute sessions that include whole-group instruction, three small-group rotations, and whole-class wrap-up.

The evidence for READ 180® covers students in 4th grade through 6th grade.

The outcomes examined include: alphabetics, comprehension, literacy achievement, and reading fluency. Here’s what the evidence suggests about READ 180® ’s impact on each outcome:

  • Alphabetics: No detectable impact
  • Comprehension: Positive impact (an average student would be expected to improve by 6 percentile points)
  • Literacy achievement: Positive impact (an average student would be expected to improve by 4 percentile points)
  • Reading fluency: Positive impact (an average student would be expected to improve by 4 percentile points)

The studies looking into READ 180® had student samples that had students who were White, Black, and Hispanic, were male and female, and were English language learners, and received free & reduced price lunch.
