According to the International Dyslexia Association, about 13-14% of the students in the United States qualify for special education. Roughly half of these students have a learning disability, or LD. Of those with LD, 85% experience primary deficits in reading and language. Overall, between 15-20% of the general population display symptoms of dyslexia, the most common language-based learning disability.
Fortunately, there is plenty of information on how to address the needs of these children. Strategies and resources to help children with learning disabilities are available on Reading Rockets and our sister site, LD OnLine.
