What is an academic indicator of reading disability established by the National Reading Panel Report?

The correct choice highlights phonological deficits as a well-documented academic indicator of reading disability, as established by the National Reading Panel Report. Phonology refers to the way sounds function in a language, and being able to recognize and manipulate these sounds is critical for developing reading skills, particularly in early literacy development.

Research shows that individuals with reading disabilities often experience significant difficulties with phonological processing, which can manifest as challenges in blending sounds, segmenting words into their constituent sounds, and recognizing rhymes. This phonological awareness is foundational for decoding words and understanding the relationship between spoken and written language.

While vocabulary, comprehension skills, and writing are also important components of literacy, the specific focus on phonological deficits establishes a clear link to the underlying phonemic awareness needed for reading. Phonological processing problems are consistently identified as a core characteristic of reading disabilities, making this the most accurate academic indicator according to the National Reading Panel.
