Dyslexia is a specific learning disability that affects language.
A child with dyslexia will have difficulty reading accurately and fluently.
Spelling will be poor. Most children with dyslexia have weaknesses in phonological processing. Many also have weaknesses in rapid naming.
Most standardized, norm-referenced tests that are used to test for learning disabilities are also used to evaluate children for dyslexia.
Is the school telling you something that just doesn't sound right? You need to educate yourself about dyslexia and how kids with dyslexia learn to read.
The word, dyslexia has always been recognized as a learning disability in federal law. See the definition of "specific learning disability" in the federal law and special education regulations.
But, the label is not important. It is essential that your child gets the proper instruction so he can learn to read.
