Research

The Heggerty curriculum is backed by research and the science of reading

The National Reading Panel found that phonemic awareness instruction helped children of all levels improve their reading, including:

  • Normally developing readers
  • Children at risk for future reading problems
  • Disabled readers
  • Preschoolers, kindergartners,
    and 1st graders
  • 2nd through 6th graders (most of whom were disabled readers)
  • Children across various SES levels
  • Children learning to read English as well as other languages

Studies have shown that phonemic awareness is a foundational skill, essential for learning to read. As students learn to identify sounds through oral and auditory activities, they become phonemically aware. Engaging in phonemic awareness instruction develops students’ understanding of sounds, and that knowledge directly impacts their spelling and writing.

Phonological awareness difficulties represent the most common source of word-level reading difficulties.

First grade Phonological awareness continues to develop in typical readers beyond first grade.

Reading problems can be prevented if all students are trained in letter-sound skills and phonological awareness, starting in Kindergarten.
