According to the Alabama Dyslexia Resource Guide, "Dyslexia impacts between 10% and 20% of children in Alabama schools."
Excerpt from the Introduction in the Alabama Dyslexia Resource Guide:
You may find the Dyslexia Resource Guide in the Alabama Reading Initiative's section of the Alabama State Department of Education's web site (click on the tab at the top of this blog). Be sure to check the data stamp on the document to see which version you are downloading. This document has been revised numerous times and will likely continue to be a work in progress, as we strive to make it the best resource possible for Alabama teachers and administrators.
