Phonemic awareness is one of the foundational skills that helps children become successful readers. It is the ability to hear, identify, blend, segment, and manipulate the individual sounds—or phonemes—in spoken words. Research reviewed by the National Reading Panel found that phonemic-awareness instruction improves children's reading and spelling, with benefits that can persist beyond the period of instruction.

Why does this matter when a child encounters a word they have never seen?
To decode an unfamiliar word such as ship, a child needs to recognize that the printed letters represent individual sounds:
sh → /sh/
i → /ĭ/
p → /p/
The child then blends those phonemes:
/sh/ /ĭ/ /p/ → ship
A child with strong phonemic awareness understands that spoken words are composed of individual sounds that can be blended and separated. When systematic phonics instruction connects those sounds to letters, the child gains a strategy for figuring out unfamiliar words instead of relying on pictures, context, guessing, or memorization. The National Reading Panel specifically identified blending as necessary for decoding unfamiliar words. (NICHD)
Current evidence-based guidance from the Institute of Education Sciences likewise gives strong evidence to teaching children awareness of speech sounds and how those sounds connect to letters, followed by explicit instruction in decoding and word recognition. (Institute of Education Sciences)
This is why I place such importance on early phonemic-awareness instruction. We aren't simply teaching children sounds—we are giving them tools they can use to unlock words they have never encountered before. As words become more complex, that strong foundation continues to support decoding, spelling, fluency, and ultimately reading comprehension.
