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 Phonological Awareness Training’s impact on students. Here’s the short version:

Phonological Awareness Training is a general practice aimed at enhancing young children’s phonological awareness abilities.

The evidence for Phonological Awareness Training covers students in pre-kindergarten.

The outcomes examined include: phonological processing. Here’s what the evidence suggests about Phonological Awareness Training’s impact on each outcome:

  • Phonological processing: Positive impact (an average student would be expected to improve by 27 percentile points)

The studies looking into Phonological Awareness Training had student samples that were in urban areas in Washington, had students who were White, Black, and Asian, and were male and female.
