Dyslexia is a neurologically based learning difference that presents a range of symptoms that cause reading, spelling and in some cases comprehension challenges. Some subtypes of dyslexia are more easily recognized (and more common) than others. Recognizing a child's dyslexia subtype makes it easier to match a remediation or approach that would meet these challenges.
Students with dyslexia can have a few different dyslexia subtypes and mild to acute levels of that subtype. Experts differ in their view of how many different subtypes there are, but agree on the main subtypes. However, a dyslexia subtype means that the student's weakness is most pronounced in that area - this indicates that remediation of the most difficult area is a good starting point.
The Feifer Assessment of Reading (FAR) is an evaluation program that addresses four specific subtypes:
